10- Firmware Development:

Before starting the development, we recommend that you make yourself familiar with Microchip

MPLABX IDE and MPLAB Harmony. Note that MPLAB Harmony has to be added as a plugin to the All

the examples we provide have been setup using MPLAB Harmony. We provide examples of source

code that show how to develop a code for the Ping Pong in addition to how to establish

communications between the microcontroller and interconnected module. The examples include

RTOS, Ethernet, USB CDC, communicating with Telit Cellular module, receiving GPS NMEA messages,

writing and reading to memory, and reading and writing to Inputs and Outputs.

The Ping Pong uses a 24MHz clock oscillator. So the oscillator configuration bits should be EC. The

following configuration bits are recommended (and mandatory when using the Boot loader):

/*** DEVCFG0 ***/

#pragma config DEBUG = ON

#pragma config JTAGEN = OFF

#pragma config ICESEL = ICS_PGx1

#pragma config TRCEN = ON

#pragma config BOOTISA = MIPS32

#pragma config FECCCON = OFF_UNLOCKED
