6) µVision Software Packs Download and Install Process: 1) Start µVision and open Pack Installer:

1. Connect your computer to the internet. This is normally needed to download the Software Packs.

2. Start µVision by clicking on its desktop icon.

3. Open the Pack Installer by clicking on its icon: A Pack Installer Welcome screen will open. Read and close it.

4. This window opens up: Select the Boards tab: Select Infineon XMC1200 Boot Kit and then select the Packs tab as shown: The Packs tab is now filtered to list only the relevant Pack to the Boot Kit.

5. Note “ONLINE” is displayed at the bottom right. If “OFFLINE” is displayed, connect to the Internet before continuing.

6. If there are no entries shown because you were not connected to the Internet when Pack Installer opened, select Packs/Check for

Updates or to refresh once you have connected to the Internet.

2) Install The XMC1000 Software Pack: The Packs tab should be selected by default.

1. Initially, the Software Pack ARM::CMSIS is installed by default. These contain system headers and source files.

2. Select Infineon::XMC1000_DFP and click on Install. This Software Pack will download and install to C:\Keil_v5\ARM\Pack\Infineon\XMC1000\ by default. This download can take two to four minutes.

3. A Software Pack status is indicated by the “Up to date” icon:

TIP: If you click on the Devices tab, you can select the processor you are using and only the relevant Packs are displayed.

3) Install the CMSIS-RTOS Blinky MDK 5 Example:

1. Select the Examples tab.

2. Select CMSIS-RTOS Blinky as shown:

3. Select Copy as shown here:

4. The next window opens up: Select Use Pack Folder Structure and unselect Launch µVision:

5. Type in C:\MDK. Click OK to copy the RTX_Blinky project.

6. This will copy to C:\MDK\Boards\Infineon\XMC1200 Boot Kit\. Pack Installer creates the rest of the directory tree after C:\MDK\.

TIP: The default directory for copied examples the first time you install MDK is C:\Users\<user>\Documents. For simplicity, we will use the default directory of C:\MDK\ in this tutorial. You can use any directory you prefer.

7. Close the Pack Installer. You can open it any time by clicking on its icon.

8. Select Yes when Reload Packs? box is displayed. This updates the µVision Pack database.

4) Install the Blinky5, RTX_Blinky5 and DSP5 examples from Keil.com:

1. Obtain the example software zip file from www.keil.com/appnotes/docs/apnt_263.asp.

2. Unzip this into the directory C:\MDK\Boards\Infineon\XMC1200 Boot Kit\.

3. Blinky5, DSP5, PWM_Blinky, RTX_text and RTX_Blinky5 folders will be created:

TIP: An Update icon means there is an updated Software Pack available for download.

TIP: If you look in C:\Keil_v5\ARM\Pack\Infineon\XMC1000_DFP\1.0.2\Boards\Infineon\XMC1200 Boot Kit, you will find another RTX_ Blinky. This is the read-only version that you downloaded for backup purposes. Use only the projects you copied over from the Examples tab to the directory you chose: in this tutorial we have used C:\MDK.

The next page has a few notes on Software Packs Maintenance plus how to test the J-Link debug connection:

11) Call Stack + Locals Window: Local Variables: The Call Stack and Local windows are incorporated into one integrated window. Whenever the program is stopped, the Call Stack + Locals window will display call stack contents as well as any local variables belonging to the active function. If possible, the values of the local variables will be displayed and if not, the message <not in scope> will be displayed.

1. Stop the program and open the Call Stack and Locals window by clicking on its tab.

2. Shown below is the Locals window for the main function when the program counter is in the Delay function. This program spends most of its time in Delay() so it will probably nearly always stop there.

3. Click on Step Out (Ctrl-F11) . Only the main() function will be displayed since the program has exited Delay().

TIP: The contents of the local variables are displayed as well as names of active functions. Each function name will be displayed as it is called from the function before it or from an interrupt or exception. Exactly which local variable that will be visible or not depends on precisely where you stop the program.

When a function exits, it is removed from the list.

The last called function is at the top of this table.

This table is active only when the program is stopped.

4. Click inside the body of the Disassembly window.

5. Click on the Step In icon or F11 until you re-enter Delay():

6. Variables will update as appropriate.

7. Click on the StepOut icon Ctrl-F11 to exit the Delay function to return to main().

8. Remove any breakpoints when you are done. You can click on them individually or Ctrl-B and select Kill All.

TIP: You can modify a variable value in the Call Stack & Locals window when the program is stopped.

TIP: If the Disassembly window is in focus, using Step will cause steps at the assembly code level. If a source file is in focus, steps will be at the C or C++ level.

Call Stack: The list of called functions is displayed when the program is stopped. This is very useful for debugging when you need to know which functions have been called and are stored on the stack.

9. Set a breakpoint in the SysTick Handler function near line 27 in Blinky.c. Click on RUN if necessary.

10. The program will very soon stop executing.

19) Creating your own MDK 5 project from scratch: (without DAVE) All examples provided by Keil are pre-configured. All you have to do is compile them. You can use them as a template for your own projects. However, we will start an example project from the beginning to illustrate how easy this process is. Once you have the new project configured; you can build, load and run a bare Blinky example. It will have an empty main() function so it does not do much. However, the processor startup sequences are present and you can easily add your own source code and/or files. You can use this process to create any new project, including one using RTX.

Install the Infineon Software Pack for your processor:

1. Start µVision and leave in Edit mode. Do not be in Debug mode.

2. Pack Installer: The XMC1000 processor series Pack must be installed. This has already been done on page 4.

3. You do not need to copy any examples over.

Create a new Directory and a New Project:

1. Click on Project/New µVision Project…

2. In the window that opens, go to the folder C:\MDK\Boards\Infineon\XMC1200 Boot Kit:

3. Right click in this window and select New and create a new folder. I called it BlinkyNEW.

4. Double click on BlinkyNew to open it or highlight it and select Open.

5. In the File name: box enter Blinky. Click on Save.

6. This creates the project Blinky.uvproj in C:\MDK\Boards\Infineon\XMC1200 Boot Kit\BlinkyNEW.

7. As soon as you click on Save, the next window opens:

Select the Device you are using:

1. Expand Infineon and then XMC1000 Series, then expand XMC1201 and then select XMC1200-TO38x0200 as shown here:

TIP: Processor icons in green are from the Software Packs. Grey icons are from MDK 4.7x.

2. Click OK and the Manage Run Time window shown below bottom right opens.

Select the CMSIS components you want:

1. Expand all the items and select CMSIS/CORE and Device/Startup as shown below. They will be highlighted in Green indicating there are no other files needed. Click OK.

2. Click on File/Save All or select the Save All icon:

3. The project Blinky.uvproj will now be copied to Blinky.uvprojx.

4. You now have a new project list as shown on the bottom left: The appropriate CMSIS files you selected have been automatically entered and configured for the processor you chose. There are no user source files yet.

5. Note the Target Selector says Target 1. Highlight Target 1 in the Project window.

6. Click once on it and change its name to XMC1200 Flash and press Enter. The Target selector name will change.

What has happened to this point:

You have created a blank µVision project using MDK 5 Software Packs. All you need to do now is add your own source files.

TIP: Other components such as File System, Graphics, Network and USB are part of Keil Middleware in MDKpro. Consult Keil tech support.

Compile and Run Your RTX BlinkyNEW Project:

1. Build the files. If there are errors or warnings please fix these before continuing.

2. Program the Flash:

3. Enter Debug mode: Click on the RUN icon.

4. No LEDS will blink. This program does not use them.

Add the two global variables countA and countB to the Watch 1 window.

5. Right click on countA and select Add countA to… and select Watch 1.

6. Right click on countB and select Add countB to… and select Watch 1.

7. These two variables will be displayed in Watch 1 and will be incrementing as shown here:

Congratulations: Your First RTX program is running correctly !

TIP: counter and SystemCoreClock are left over from previous steps.

Open the System and Threads Viewer:

8. Select Debug/OS Support and select System and Threads Viewer. the following window opens up: You probably have to drag into the middle of your screen.

9. The various elements will be updating in real-time as your RTX program is running.

10. Note the idle daemon is running most of the time. You can change this ratio if you want to.

11. Set a breakpoint in each thread.

12. Each time you click on RUN the program will advance to the next thread repeatedly.

13. The active thread will display Running in the State column.

This ends the exercise creating your own RTX Blinky project. You can easily add more threads and modify the timing. When you are finished, stop the program and leave Debug mode. Obtain the Keil Getting Started MDK 5 manual: www.keil.com/mdk. It contains valuable information of using RTX. Extensive help files are included with MDK 5. So far, we have created projects from scratch or a fundamental beginning. The next section deals with creating projects using Infineon DAVE.



23

PART C: Creating projects with Infineon DAVE and MDK 5: This document uses DAVE 3.1.10 to create both a Blinky and an RTX_Blinky project. Please install DAVE to your computer in the usual manner. This action will install the correct J-Link USB drivers. Select Help/Check for Updates to make sure you have the latest software.

You must have downloaded the XMC1000 Packs into µVision as shown on page 4.

21) Blinky using DAVE: We will create a µVision project using DAVE to blink the two LEDs on the Boot Kit board. Two PWMs will be created and configured: each one blinks one LED. DAVE will then create a µVision project and µVision will then import it.

Start DAVE and create a DAVE project:

1. Start DAVE by clicking on its icon:

2. Select File/New/Dave Project and this window will open:

3. Select DAVE CE Project: Always select CE.

4. In Project Name box enter Blinky as shown here:

5. Select Next > and the Target Selection Page opens:

6. Select XMC1200-TO38F200 or the processor you are using as shown in the Target Selection window:

7. Confirm Add/Update startup files is enabled.

8. Click on Finish. DAVE will create your project.

9. The Blinky project will be displayed in the DAVE C/C++ Projects window as shown below.

10. Expand some of the elements.

11. You will see a Main.c and two CMSIS startup files.

12. Double click on Main.c, it will open in a window.

13. You can see DAVE has created a template Main.c with an int main(void) function but not much else.

14. If you open the startup files found in the Startup folder, you can see startup_XMC1200.s which contains processor initialization code and system_XMC1200.c contains mostly clock settings.

TIP: DAVE dynamically saves all your work as you progress into your default workspace: C:\DAVE3_workspace. You can manually save your work with File/Save or Ctrl-S.

15. We will next create two PWMs to blink the LEDs.

Configure PWM /0:

1. Right click on PWMSP001/0 and select UIEditor. This window opens up: 2. Set Start to Start during initialization: 3. Set CCU4 Resolution to 32000 nsec. 4. Set PWM freq to 1 Hz: 5. Select the Signal Configurations tab and set

the Output Level to Passive High. 6. Leave all else at their defaults.

Connect PWM /0 output to GPIO Port Pin P0.0:

1. Right click on PWMSP001/0 again and select Manual Pin Assignment and the next window opens up.

2. Select Resource to pin_directoutput and Port Pin number P0.0/ #17 as shown below:

3. Select Solve And Save and then Close to assign this pin.

Configure PWM /1:

1. Right click on PWMSP001/1 and select UIEditor and a similar window opens up. 2. Set Start to Start during initialization: 3. Set CCU4 Resolution to 32000 nsec. 4. Set PWM freq to 1 Hz: 5. Select the Signal Configurations tab and set the Output Level to Passive Low. This puts PWMMSP001/1 180 º out

of phase with PWMMSP001/0. When one LED is on, the other will be off. Connect PWM /1 output to GPIO Port Pin P0.7:

1. Right click on PWMSP001/1 again and select Manual Pin Assignment and the next window opens up. 2. Select Resource to pin_directoutput and Port Pin number P0.7/ #24 as shown below:

Note: P0.0 is no longer listed. DAVE knows you have already assigned Pin 0.0 so it removes it from the list.

3. Select Solve And Save and then Close to assign this pin. 4. The PWMs are now completely configured. All we need do is Build the project and export it into µVision 5.

TIP: If your entries do not seem to work: ensure they are accepted by pressing Enter or clicking on another element.



26

Generator Package Description (gpdsc) File: DAVE produces a complete µVision project and in addition a gpdsc file. This file is used to start, import and configure the appropriate files into µVision.

Configure DAVE to create a gpdsc file: (you only have to do this once in DAVE for all your projects)

1. In the DAVE main window, select Window/Preferences and this window opens up:

2. Expand Dave and select DAVE CE Preferences as shown here:

3. Select Generate gpdsc file as shown:

4. Click on OK.

Generate the Code:

5. Click on the Generate Code icon or select DAVE/Generate Code.

6. The appropriate files will be created and a progress bar will be displayed.

7. The C/C++ Projects window will display the files in this project.

8. Blinky.gpdsc will be visible in the window as shown below right:

TIP: If you do not want another instance of µVision running, close the running instance(s) before double clicking on the gpdsc file. Running multiple instances of µVision is permitted but a conflict with the J-Link Lite might arise in this case. Import into µVision:

1. Close µVision running. See the TIP: above.

2. Double click on Blinky.gpdsc and a new instance of µVision will be started.

TIP: At this time you can shut DAVE down if you prefer. It is not needed again unless you want to add or modify any settings that must be done in DAVE. Otherwise, µVision can work stand alone with the files DAVE created for it.

On the next page, we will configure µVision, build the project, program it to Flash and run it.

22) Create an RTX_Blinky project using DAVE and MDK 5: We will create a µVision project using DAVE to blink the two LEDs on the Boot Kit board. RTX is used. We will use direct software control of Ports 0.0 and 0.7 to blink the LEDS using two simple threads. DAVE will then create a µVision project and µVision will then import it. It is easy to add additional threads.

TIP: It is useful in DAVE to click on Help/Check for Updates and also DAVE App Updates.




3. Select DAVE CE Project: Always use DAVE CE.

4. In Project name box enter RTX_Blinky as shown here:





9. The Blinky project will be displayed in the C/C++ Projects window as shown below.




13. You can see DAVE has created a template main.c with an int main(void) function but not containing much else.

14. If you open the startup files, you can see startup_XMC1200.s which contains processor initialization code and system_XMC1200.c which contains mostly clock settings.

TIP: DAVE dynamically saves all your work as you progress with your workspace. You can manually save your work with File/Save or Ctrl-S.

15. On the next page, we will create and configure the two IO ports to blink the LEDs.



31

DAVE Apps:

Dave includes Apps that you can graphically configure to create programs to suit your needs. We will use the RTOS001 App and two instances of the Software Controlled IO App IO004 to create our demonstration program. TIP: You can also create a project with the RTOS App and implement RTX using µVision as described on page 20.

TIP: Your version numbers listed for each App might be different from the ones shown in the screens here. Always use the versions shown or later only.

In this project, RTX RTOS files are supplied by DAVE.

Apps available are listed in the App Selection View.

1. Scroll through them to see your options.

2. If you hover your mouse over an App, a description of it will display as shown in this window.

3. We will use two instances of the App IO004 to blink each LED on and off directly through the GPIO ports.

4. Enter io in the Search filter as shown here: Press Enter to make it active.

Create Two IO ports to Control the LEDs:

6. Under the heading I/O Ports/Software Controlled I/O App, double click on IO04 as shown here:

7. This will be added in the S/W App Connectivity View.

8. Double click again on the same IO04 App.

9. The second instance will now be added:

10. Your S/W App Connectivity View will contain the two IO Apps. There are two instances of IO04 (denoted by /0 and /1)

Create the RTX RTOS001 Instance:

11. Enter rtos in the Search filter as shown here: Press Enter to make it active.

12. Double-click on RTOS001. This will be entered in your project.

13. The clock CLK002/0 is inserted automatically by DAVE.

14. Your completed App Connectivity View will look like the one below. You can move the icons around.

15. The next steps will configure the IO and RTOS Apps.

TIP: To use the RTX that comes with µVision, do not create an RTOS001 above. In the Manage Run-time Environment select RTX. See page 35 under Manage RTE in step 6.

TIP: App Help: Select Help and click on Help Contents. On the left click on DAVE Apps. A listing of the Apps will open.



32

Configure IO004/0: 1. Right click on IO004/0 and select UIEditor. This window opens up: 2. Enable Output Enable as shown here: 3. Set Default Output level to High: This will cause the

LEDs to blink alternatively. 4. Leave all else at their defaults.

Connect IO004/0 output to GPIO Port Pin P0.0: 5. Right click on IO004/0 again and select Manual Pin

Assignment and the next window opens up. 6. Select pin in the Resource box. Select P0.0/ #17 in

the Port Pin Number box as shown below: 7. Select Solve And Save and then Close to assign this

pin. Configure IO004/1:

1. Right click on IO004/1 and select UIEditor and a similar window to the one above opens up. 2. Enable Output Enable as shown above the same way you configured IO004/0. 3. Unselect Default Output level/ High. This will cause the LEDs to blink alternatively.

Connect IO004/1 output to GPIO Port Pin P0.7:

4. Right click on IO004/1 again and select Manual Pin Assignment and the Manual Pin Assignment window opens. 5. Select Resource to pin and Port Pin number P0.7/ #24 similar to the above screen. 6. Select Solve And Save and then Close to assign this pin. 7. The IO ports are now configured.

Configure RTOS001/0:

1. Right click on RTOS001/0 and select UIEditor, The window that opens has four tabs:

2. We can use the default values. 3. Click on each tab to view the selections available.

Leave everything at their default values. 8. It is possible to modify the same settings in the file in

µVision. It is best to make any modifications inside DAVE rather than from µVision.

9. RTX is now completely configured. All we need do is Build the project and export it into µVision 5. We will need to add an application source code to Main.c.



33

Generator Package Description (gpdsc) File: DAVE produces a complete µVision project and in addition a gpdsc file. This file is used to start, import and configure the appropriate files into µVision.

Configure DAVE to create a gpdsc file: TIP: You need set the Generate gpdsc bit only once for all your DAVE projects.



3. Select Generate gpdsc file as shown:

4. Click on OK.

Generate Code.




4. Blinky.gpdsc will be visible as shown in the screen below right:

.

Import into µVision:

1. Close µVision. This prevents multiple instances from opening.

2. Locate the file Blinky.gpdsc as shown here:

3. Double click on Blinky.gpdsc and a new instance of µVision will be started.

TIP: If you do not want another instance of µVision running, close the running instance(s) before double clicking on the gpdsc file. Running multiple instances of µVision is permitted but a conflict concerning the J-Link Lite might arise in this case. On the next page, we will configure µVision, add source files, build the project, program the Flash and run it.

4. You can optionally close DAVE now. We will not need it.

23) PWM Controlled Blinky using DAVE We will create a µVision project using DAVE to blink one LED on the Boot Kit board. A PWM App will be used and configured: it blinks the LED (slowly changing the brightness). Also, a Counter App will be used to count the PWM pulses. An interrupt on the count match toggles between increasing and decreasing the brightness intensity of the LED. DAVE will then create a µVision project and µVision will then import it.




3. Select DAVE CE Project: Always select CE.

4. In Project Name box enter PWM_Blinky as shown here:





9. The Blinky project will be displayed in the DAVE C/C++ Projects window as shown below.




13. You can see DAVE has created a template Main.c with an int main(void) function but not much else.

14. If you open the startup files found in the Startup folder, you can see startup_XMC1200.s which contains processor initialization code and system_XMC1200.c which contains mostly clock settings.

TIP: DAVE dynamically saves all your work into the default workspace: C:\DAVE3_workspace. You can manually save your work with File/Save or Ctrl-S.

15. We will next create two PWMs to blink the LEDs.



39

DAVE Apps:

DAVE includes Apps that you can graphically configure to create programs to suit your needs. These are programs DAVE uses to create the source code files that will become part of your µVision project.

1. Apps are listed in the App Selection View.

2. Scroll through them to see your options.

3. If you hover your mouse over an App, a description of it will display.

4. We will use one instance of the App PWMSP001 to blink the LED on and off.

5. We will use one instance of the App CNT001 to count the number of PWM pulses.

6. We will use two instances of the App NVIC002 to react on interrupts on the PWMSP001 and CNT001.

Create the Apps:

1. Enter pwm in the Search filter as shown here:

2. Under the heading PWM Generation, double click on the App PWMSP001 as shown here:

3. This will be added in the S/W App Connectivity View. 4. Enter cnt in the Search filter. 5. Under the heading Signal Capture, double click on the App

CNT001. 6. The Apps Shareability window will open. Select

app/ccu4global/0 as shown below on the right: 7. Click on OK. 8. Enter nvic in the Search filter. 9. Under the heading NVIC (Nested Vectored Interrupt

Controller), double click on the App NVIC002. 10. It will be added to the S/W App Connectivity View. 11. Double click again on the same NVIC002 App. A second

instance of it will be added. 12. Your S/W App Connectivity View will be similar to the

one shown below: You can move your Apps around. 13. Note there are two instances of NVIC002 (denoted by /0

and /1), a Capture/CompareUnit 4 and a CLK002/0 clock App.

14. These last two Apps are automatically inserted by DAVE.



40

Configure PWMSP001/0:

1. Right click on PWMSP001/0 and select UIEditor. The window below opens up: 2. First, in the Timer Configuration, set CCU resolution units to usec. 3. Then set CCU4 Resolution to 10. 4. Set PWM freq to 100 Hz 5. In the Interrupts area, enable Period Match: Enable at initialization. 6. Select the Signal Configurations tab and set the Output Level to Passive High. 7. Leave all other settings at their defaults.

Connect PWMSP001/0 output to GPIO Port Pin P0.0:

1. Right click on PWMSP001/0 again and select Manual Pin Assignment and the next window opens up. 2. In the Resource column, select pin_directoutput and Port Pin number P0.0/ #17 as shown below: 3. Select Solve And Save and then Close to assign this pin.



41

Configure CNT001:

1. Right click on the App CNT001/0 and select UIEditor. The window below opens up. 2. Set Event Count Match to 400. 3. In the Interrupts area, select Count Match to Enable at initialization as shown below:

Add User Labels to the NVIC002:

1. Right click NVIC002/0 and select Add User Label. 2. Enter PWM_Period and click OK. 3. Right click NVIC002/1 and select Add User Label. 4. Enter CountMatch and click OK. 5. Your apps will now look like this with labels attached:

They are probably in different physical locations.

Configure NVIC002/0 (PWM_Period):

1. Right click NVIC002/0 (PWM_Period) and select UIEditor and the window below opens:

2. Set the Preemption Priority to 2. 3. Select Enable interrupt at initialization. 4. Set the User defined interrupt handler to PWM_Period_Handler. 5. Press Enter or click away to ensure this handler is accepted.

Configure NVIC002/1 (CountMatch):

1. Right click NVIC002/1 (CountMatch) and select UIEditor.

2. A similar screen opens. 3. Set the Preemption Priority to 3. 4. Select Enable interrupt at initialization 5. Set the User defined interrupt handler to

CountMatch_Handler. 6. Press Enter to ensure this handler is accepted.



42

Configure Signal Connections: One of the advanced features of DAVE3 is the option for the user to connect signals between different DAVE Apps. An important use for this feature is the connection of an event signal with the interrupt signal of an NVIC (interrupt) App.

PWMSP001/0 Signal Connections:

1. In the S/W App Connectivity View Right click on PWMSP001/0 and select Signal Connection. The window below opens:

Connect NVIC002/0

2. In the first Signal column, select Period Match Interrupt. 3. In the App column, select the NVIC002/0 App to connect to. 4. In the second Signal column, select Interrupt Node. 5. Click Solve and Save. Do not select Close yet. We are not quite done.

Connect CNT001/0

6. A new signal row will be created. 7. In the first Signal column, select PWM Status. 8. In the App column, select CNT001/0 to connect to. 9. In the second Signal column, select Input as the Signal. 10. Click Solve and Save. Your window will like the one below. If not, please make any changes and Solve and Save. 11. Click Close.

CNT001/0 Signal Connections:

1. In the S/W App Connectivity View, right click on CNT001/0 App and select Signal Connection. The window below opens.

2. In the first Signal column, select Event Count Match Interrupt. 3. In the App column, select NVIC002/1 (Count Match) to connect to. 4. In the second Signal column, select Interrupt Node as the Signal. 5. Click Solve and Save. Your window will look like the one below. If not, please edit and Solve and Save. 6. Click Close.

At this point, all the Apps we need for the PWM_Blinky project are now configured.



43

Generator Package Description (gpdsc) File: DAVE produces a complete µVision project and in addition a gpdsc file. This file is used to start, import and configure the appropriate files into µVision. DAVE must be configured to generate this gpdsc file.

If you did this task on page 26, you do not need to repeat it. Jump to Generate the Code below:

Configure DAVE to create a gpdsc file: (you only have to do this once in DAVE for all your projects)



3. Select Generate gpdsc file… as shown:

4. Click on OK.

Generate the Code:




8. PWM_Blinky.gpdsc will be visible in the window as shown below right:

9. You are ready to import this into µVision.

Import into µVision:

1. Close any instances of µVision. See the TIP below.

2. Double click on PWM_Blinky.gpdsc and a new instance of µVision will be started.

TIP: If you do not want another instance of µVision running, close any running instance(s) of µVision before double clicking on the gpdsc file. Running multiple instances of µVision is permitted but a conflict with the J-Link Lite might arise in this case. TIP: At this time you can shut DAVE down if you prefer. It is not needed again unless you want to add or modify any settings that must be done in DAVE. Otherwise, µVision can work stand alone with the files DAVE created for it.

On the next page, we will configure µVision, add some source code to PWM_Blinky.c, build the project, program it to Flash and run it.

Add Application Code to Main.c:

Under Source Group 1, double click on Main.c in the Project window to display it. The code below is contained in the file Main.c or PWM.txt in C:\MDK\Boards\Infineon\XMC1200 Boot Kit\PWM_Blinky.

1. Add the following variable declarations below line 13 after #include <DAVE3.h>:

#include "XMC1200.h" float LED_duty = 0; enum bright {up, down}; enum bright LED_bright = up; uint32_t PWMerrorcount = 0; uint32_t CNTerrorcount = 0; uint32_t CountVal; PWMSP001_TimerRegsType TimerVal;

2. Add these two handler functions that have been declared for the DAVE Apps near line 27 before main(void): void PWM_Period_Handler(void) { status_t status; switch (LED_bright) { case up: {if (LED_duty > 99) LED_duty = 0; LED_duty++; } break; case down: {if (LED_duty < 1) LED_duty = 100; LED_duty--; } } status = PWMSP001_SetDutyCycle(&PWMSP001_Handle0, LED_duty); if (status != DAVEApp_SUCCESS) PWMerrorcount++; } void CountMatch_Handler(void) { status_t status; switch (LED_bright) { case up: LED_bright = down; LED_duty = 100; break; case down: LED_bright = up; LED_duty = 0; } status = CNT001_Stop(&CNT001_Handle0); if (status != DAVEApp_SUCCESS) CNTerrorcount++; status = CNT001_ResetCounter(&CNT001_Handle0); if (status != DAVEApp_SUCCESS) CNTerrorcount++; status = CNT001_Start(&CNT001_Handle0); if (status != DAVEApp_SUCCESS) CNTerrorcount++; }

3. Uncomment the declaration of the variable status in main. 4. Add these lines after DAVE_Init(); which is near line 70:

status = PWMSP001_Start(&PWMSP001_Handle0); if (status != DAVEApp_SUCCESS) PWMerrorcount++; status = CNT001_Start(&CNT001_Handle0); if (status != DAVEApp_SUCCESS) CNTerrorcount++;

5. Add these lines inside the while loop: status = PWMSP001_GetTimerRegsVal((PWMSP001_HandleType*)&PWMSP001_Handle0, &TimerVal); if (status != DAVEApp_SUCCESS) PWMerrorcount++; status = CNT001_GetEvtCountValue((CNT001_HandleType*)&CNT001_Handle0, &CountVal); if (status != DAVEApp_SUCCESS) CNTerrorcount++;
