Explorer 16/32 Development Board User's Guide - Developer Help
Once the PKOB has been selected in the IDE, the device should operate as a
normal programmer/debugger tool. Information on how to use the IDE to perform
programming and debug operations can be found within the MPLAB Help
documentation.
When using the PICkit On Board circuit, make sure that no other ICSP based
programmer/debugger tool is attached to the PIM microcontroller simultaneously,
through the RJ11 jack JP1, or the 6-pin inline header footprint J14. The PICkit On
Board circuit, JP1, and J14 all share access to the same PIM microcontroller's ICSP
interface pins, so interference/contention (albeit current limited by series resistors) is
possible if more than one programming/debug tool is simultaneously connected.
Similarly, if an external programmer/debugger tool will be used instead of the PKOB
circuit, it is recommended to unplug the USB connection on J18, so as to ensure
that the PKOB circuit is held in reset and does not interfere or contend with the
external programmer/debugger tool.
Differences from Classic Explorer 16 (Rev 5.1 and earlier)
The Explorer 16/32 Development Board design was developed from the popular
Explorer
/DM240001)). For details and schematics of the classic Explorer 16 board design,
see the Explorer 16 Development Board User's Guide (http://ww1.microchip.com
/downloads/en/DeviceDoc/50001589b.pdf).
The Explorer 16/32 Development Board can be distinguished from the classic
Explorer 16, by the silk screen and PCB copper layer revision numbers. The
Explorer 16/32 board has the text "EXPLORER 16/32" prominently printed in the
upper right quadrant of top side of the PCB, and will have board revision number of
at least 6.3 (printed on the bottom side copper layer, in the upper middle of the
PCB). The classic Explorer 16 Development board instead shows silk text "Explorer
16 Development Board" on the top right quadrant of the board, and will have PCB
revision number 5.1 or lower printed on the bottom side copper layer.
The Explorer 16/32 Development Board was designed to maintain as much
backwards compatibility with existing Explorer 16 based firmware projects as
possible, while still modernizing and improving several aspects of the design. Some
of the key differences in the new board include:
USB female Type-C (supporting both host and device modes) and USB female
A connectors have been added. It is no longer necessary to use the AC164131
(http://www.microchip.com/AC164131) USB PICtail Plus daughter card when
designing USB applications.
PICkit on board (PKOB) circuit added – Allows one to get started using the
