Integrated Development Environment IDE combines an editor, project manager, code development tools and a debugger into a single, intuitive environment for code development and in-system debug.

IDE (cont.)

A --Standard Windows® Menus and Toolbars provide optimum access to all IDE features including the editor, debugger, customizable tool menu and online help.

B --Project Window offers clear visibility and easy management of all files associated with design project.

C --Source Editor Window helps create programs using the language-sensitive, full featured editor. Debugging assembly or C language programs with the source in full

view is supported. Useful debug features, such as breakpoint markers and program counter location, dramatically speed debugging.

D -- Output Window conveniently displays the assembler output and listing file.

E,F -- Register Windows and Memory Windows help in examining and directly modifying memory, register and Flash contents during debugging. These flexible windows are automatically updated each time program execution stops, and values that changed are highlighted.

Compiler & Cross Compiler

Compiler: Compiler is a software program which converts programming

language to machine understandable code .C -.obj

Cross-Compiler: A cross compiler is a compiler capable of creating executable code

for a platform other than the one on which the compiler is running. Cross compiler tools are used to generate executables for embedded system or multiple platforms.

8

Assembler and Disassembler

Assembler: Assembler is a software or a tool that translates Assembly language to

machine code. So, an assembler is a type of a compiler and the source code is written in Assembly language. Assembly is a human readable language but it typically has a one to one relationship with the corresponding machine code.

.asm- .obj

Disassembler :

A disassembler is a Computer program that translates machine language into assembly language the inverse operation to that of an assembler.

.obj -- .asm

Library and Linker

Library is an order specially formatted program collection of the object codes such that a linker can use required ones directly for linking with another newly developed source file. library manager helps in creating libraries

Linker - Linker creates an absolute object module from other modules it takes object modules created by an assembler and a complier or it takes object modules created by an RTOS. It takes only the needed object modules from the library. An absolute object file has all code and data at the fixed non-re locatable addresses.

Object to Hex Converter- It converts object files to Hex files

Debugger

Debugger provides for menu and commands as follows:

(a) Start or stop debugging

(b) Performance analyzer( to find execution time for the functions and for the specified addresses ranges and display in the performance analyzer window

(c) Break points - Open a dialog box for the break points insertion or deletion and break points settings, enable or disable current line break point, kill all break points and disable all break points

(d) Go( run and execute) up to next break points

(e) Step and step over by Executing one step into function and executing single step

over a function

(f) Step out of current function

12

Simulator

A simulator helps debugging and thus in the development of the tested system before the final target system is readied.

It is used during the development phase.

A simulator does target debugging. It selects a specific microcontroller version in the family and specific peripherals for simulation.

It simulates the hardware performance for the software to be embedded in that without actually employing the specific device (micro controller)

13

Device Programmer

Device Programmer allows the selection of the device and then uses the Hex file for burning the codes using a ribbon cable that connects to device

Device Programmer burns the code from the Hex file record of the absolute object file for an application. Burning means putting the codes in PROM.

14

Emulator

Emulator is a hardware which duplicates the features and functions of a real system, So that it can behave like an actual system.

Microcontroller application codes for robot. Robots interfaces with difference sensors and get the different inputs at different instances. Similarly it generates different outputs for the motors as per the input received.

An emulator can emulate the I/O’s in the robotic application during development phase.

15

In Circuit emulator

It has RS232C COM port to interface with the PC.It emulates 8051 system.

An emulator has emulating circuit for target system I/O’s.

Emulator and ICE emulate the inputs and control the outputs and emulate serial ports and timer of an application without actually building a circuit with an 8051 target version installed in that.

In circuit emulation can also refer to the use of hardware emulation, when

the emulator is plugged into a system in place of yet to be built chip.
