Emulator

Using REAL ICE

Install the Latest SoftwareInstall the MPLAB®IDE software onto your PC using the MPLAB IDE CD-ROM or download it from www.microchip.com/MPLAB. Check the latest Release Notes for additional information. DO NOT run the MPLAB IDE program at this time.

Configure USB CommunicationsConnect the MPLAB REAL ICE™ In-Circuit Emulator to a PC USB port via a USB cable. If the drivers do not install automatically, follow the steps in the HTML file at C:\Program Files\Microchip\MPLAB IDE\REAL ICE\Drivers (for 32-bit OSs) or C:\Program Files(x86)\Microchip\MPLAB IDE\REAL ICE\Drivers 64 (for 64-bit OSs).

Connect to Target Device

Use the supplied loopback test board to verify that the emulator is functioning properly: 1. Disconnect the emulator from the PC.2. Plug the standard driver board into the emulator pod.3. Plug the loopback test board into the pod’s logic probe socket.4. Connect the loopback test board to the standard driver board

using the modular cable.5. Reconnect the emulator to the PC.6. Launch MPLAB IDE, then select “REAL ICE” from the Debugger

or Programmer menu.7. Select Debugger>Settings or Programmer>Settings, Status tab,

and click Run Loopback Test to verify the emulator is working.8. After verfiying the emulator operation, disconnect the loopback

test board from the emulator.

1. In MPLAB IDE, select “None” from the Debugger or Programmer menu.

2. Attach the emulator to the target as shown to the right. Remove USB power first if switching to HS communications. 3. Connect power to the target board.

Configure MPLAB IDE1. Find currently-supported devices in the release notes in

Help>Release Notes>MPLAB REAL ICE Emulator Release Notes or at www.microchip.com/dts.

2. Select your device: Configure>Select Device.3. Select the MPLAB REAL ICE in-circuit emulator as a debugger

(Debugger>Select Tool>REAL ICE) or as a programmer (Programmer>Select Programmer>REAL ICE).

4. When using the emulator as a debugger, select “Debug” on the toolbar to reserve program memory and RAM space:

High-Speed Connectionat Target

Correct

*Target device must be running with an oscillator for the emulator to function as a debugger.**If the device has AVDD and AVSS lines, they must be connected for the emulator to operate.

• Do not use capacitors on MCLR – they will prevent fast transitions of VPP.

• Do not use pull-ups on PGC/PGD – they will divide the voltage levels since these lines have 4.7 kΩ pull-down resistors in MPLAB REAL ICE.

• Do not use multiplexing on PGC/PGD – they are dedicated for communications to MPLAB REAL ICE.

• Do not use capacitors on PGC/PGD – they will prevent fast transitions on data and clock lines during programming and debug communications.

• Do not use diodes on PGC/PGD diodes on – they will prevent bidirectional communication between MPLAB REAL ICE and the target PIC® MCU.
