Detailed Description

Support for the Digilent PIC32 WiFire.

Overview

The ChipKit Wifire is a development board by Digilent featuring a PIC32MZ and a Wifi module (MRF24WG0MA). General information about the board can be found here Please do not use board rev A or B as they use a different MCU (PIC32MZ2048ECG100).

Using UART

This board opens a serial interface through the USB automatically.

Flashing the device

There are three ways to flash the MCU: Using MPLAB-IPE and a PICkit 3 (The RIOT build generates a hexfile compatible with MPLAB-IPE) Using pic32prog and a PICkit 2 or a PICkit 3 (other devices might be supported by pic32prog but were not tested). Using a SEGGER J-Link probe. JTAG pins are available on the JP3 connector.

Supported Toolchains

For using the pic32-wifire board we strongly recommend the usage of the Codescape GNU Tools toolchain.
