ELECTROSTATIC WARNING
The PIC32-MX460 board is shipped in protective anti-static packaging. The board
must not be subject to high electrostatic potentials. General practice for working
with static sensitive devices should be applied when working with this board.
BOARD USE REQUIREMENTS
Cables:
Depends on the used programming/debugging tool. It could be 1.8
meter USB A-B cable to connect
PIC-ICD2
or
PIC-ICD2-POCKET
to USB host on PC
or RS232 cable in case of
PIC-ICD2-TINY
or other programming/debugging tools.
You will need a serial cable if not for programming, than for configuring the board.
You will also need a USB OTG cable.
Hardware:
Programmer/Debugger – most of Olimex programmers are
applicable, for example
PIC-ICD2, PIC-ICD2-POCKET, PIC-ICD2-TINY
or other
compatible programming/debugging tool.
!!!Warning!!!
When you want to program this microcontroller with PIC-ICD2,
PIC-ICD2-POCKET or PIC-ICD2-TINY, before connecting the programmer to your
target board, you should first connect the programmer to your computer and open
MPLAB. There, first from menu Configure – Select Device – choose the
microcontroller you are about to program, then from menu Programmer – Select
Programmer – choose MPLAB ICD 2, wait while MPLAB is downloading operation
system, and after ICD2 is connected – check in menu Programmer – Settings –
Power – there is option – Power target circuit from MPLAB ICD 2 – this option
should be forbidden, you could not select it. Now it is safe to connect the
programmer to your target board.
