SECTION 2
SETTING UP THE PIC-P26J50
DEVELOPMENT BOARD
This section helps you set up the PIC-P26J50 development board for the first time.
Please consider first the electrostatic warning to avoid damaging the board, then discover the
hardware and software required to operate the board.
The procedure to power up the board is given, and a description of the default board behavior
is detailed.
2.1 Electrostatic Warning
The PIC-P26J50 development board is shipped in a protective anti-static package. The board
must not be exposed to high electrostatic potentials. A grounding strap or similar protective
device should be worn when handling the board. Avoid touching the component pins or any
other metallic element.
2.2 Requirements
In order to set up the PIC-P26J50 proto board, the following items are required:
- The PIC-P26J50 development board itself
- miniUSB - USB cable
Or
- 3,3 V external power supply
Note: The board is not delivered with an ICSP debugger/programmer, which is needed if you
want to reprogram it. Remember that the connector on the board is mini ICSP (6 pin). You
may use a pair of the following devices for this purpose:
- Olimex’s PIC-ICD2-POCKET + Olimex’s PIC-ICSP
- Olimex’s PIC-KIT3 + Olimex’s PIC-ICSP
Or any compatible PIC programmer with 0,05’’ step ICSP connector.
Also, a host-based software toolchain is required in order to program/debug the PIC-P26J50
board.
Our suggestion is to use Microchip’s MPLab IDE.
