Using the Microchip development tools to program the Wi-FIRE board will cause the boot loader to be erased. To
use the board with the MPIDE again, it is necessary to program the boot loader back onto the board. The boot
loader HEX file can be found at www.digilentinc.com. To reprogram the bootloader, use the Microchip IPE which
comes with the MPLAB X tool set. The bootloader cannot be easily reprogrammed directly with the MPLAB X IDE.
12 Pinout Tables
The following tables show the relationship between the chipKIT digital pin numbers, the connector pin numbers,
and the microcontroller pin numbers.
In the following tables, columns labeled chipKIT pin # refer to the digital pin number. This is the value that is
passed to the pinMode(), digitalRead(), digitalWrite() and other functions which refer to the pin.
