OTHER TRACE METHODS – SPI OR I/O PORT TRACE
The Explorer 16 board does not have the connections to perform either SPI or I/O Port
trace. Therefore, it must either be modified or a different board must be used that allows
access to the required device SPI and Port pins.
The PIC24FJ128GA010 device and code from the beginning of this tutorial will be used
in this section. Although this device has built-in (Native) trace capability, you may wish
to use the other types of trace for speed or pin resource reasons.
For devices that do not have Native trace capability, SPI and I/O Port trace are the only
forms of trace available. The procedures shown here can be modified to use with other
Microchip devices supported by the MPLAB REAL ICE in-circuit emulator.
4.15.1
Using SPI Trace
The Explorer 16 board does have a place for connecting with the PICkit 2. This
connection can be populated to provide connection to six of the eight high-speed
communication pins. The remaining two pins - to the SPI pins SCK and SDO - will have
to be hard-wired from two additional connector pins to the appropriate SPI pins on the
device. See Section 2.4.2 “High-Speed Communication Connection” for details.
Note:
The Explorer 16 silkscreen label for pin 1 of the PICKIT2 connector is
incorrect. This is actually the location of pin 6.
You may also choose to use a target board of your own design that allows for access
to the necessary debug and SPI pins. Either way, a hardware connection between the
target board and the emulator ’s high-speed connector is required. See
more information.

HARDWARE SETUP
To set up the hardware to use SPI Trace, do the following:
1. Obtain Microchip’s Performance Pak, which contains the emulator high-speed
communication boards and cables, if you have not already done so.
Note:
High-speed communications is required to use SPI Trace.
2. Modify or create a target board, as specified above, so that it accommodates the
high-speed connector.
3. Using an unpowered emulator and target board, insert the high-speed driver
board into the emulator and the high-speed receiver board into the target board.
Communication” for reference.
4. Power the emulator, and then the target board.
