·         Device Support List

1.1      Debugging Considerations

For low pin-count devices (8 to 28 pins), a Header board is usually required. See the Header Board Specification (DS51292) or Header help file (hlpHeader.chm) for a list of available headers by device.

For high pin-count devices (40 to 100 pins), a Header board may be available, but is not required. See the Header Board Specification (DS51292) or Header help file (hlpHeader.chm) for a list of available headers for a particular device.

PICkit 2 does not support the optional header for the following devices at this time:

dsPIC33F

PIC24F/H

NOTE: To connect PICkit 2 to a debug header board requires the AC164110 RJ-11 to ICSP Adapter.

NOTE: PICkit 2 reserves 64 bytes less flash memory than the MPLAB ICD 2 for the following devices:

PIC18F2682

PIC18F2685

PIC18F4682

PIC18F4685

2      Other Support

See the Readme for MPLAB X IDE.htm for other support information.

None.

6      Known Problems

The following is a list of known problems. For more information on operation, please see the on-line help file for the PICkit 2. Bolded prefix represents internal tracking numbers.

6.1      General Issues

·         Do not change the selected device in the Project Properties when PICkit 2 is actively selected as the Debugger. Doing so may cause PICkit 2 to hang at the next debug operation. Deselect PICkit 2 as the Hardware tool (e.g. select the Simulator) before changing the device, and then reselect PICkit 2 as the Hardware tool afterwards to ensure proper operation.

·         The Programming Executive (PE) for PIC24H and dsPIC33F parts may fail on certain programming ports of certain 44-Pin devices. Known problems exist with using the PGC3/PGD3 port on the following devices:

PIC24HJ16GP304, PIC24HJ32GP204, dsPIC33FJ16GP304, dsPIC33FJ32GP204, dsPIC33FJ16MC304, dsPIC33FJ32MC204

If a “PE Error” is frequently encountered in the MPLAB X IDE Output Window, try using a different PGC/PGD programming port pair on the device.

·         To use the PICkit 2 as a debugger, two 4.7KW pull-down resistors are needed on pins ICSPDAT and ICSPCLK for units with a black pushbutton. Units with a red pushbutton have the pull-down resistors already internal to the unit.

·         Freeze Peripherals for PIC16F devices are not supported at this time.

·         PIC18F2520 MCUs: Table Read Protect (EBTRx) will not work unless Code Protect (CPx) is enabled. Also, once Table Read Protect is enabled, you cannot perform a Verify on the protected block.

ICD2-81

MPLAB PICkit 2 fails to program/verify the PIC24FJ128GA010 device when user code does runtime flash erase /write operation. It appears the device is executing code before the full programming cycle is complete.

For PIC24F devices during a programming/verify operation (or subsequent verification operation) of user code that performs self-writes and/or self-erases to program space, a verify sequence may fail if the code execution occurs within the first execution cycles following reset.

Workaround: Place a delay in your code before the code section that performs the self-write and/or self-erase.

The specific delay value may need to be adjusted, but 100 ms would be a conservative value to start

out with. Here is a C language example that illustrates the workaround:

int main (void)

{

// Place 100 ms delay here before any self-write/self-erase code

. . .
