Macros

#define TICKS_PER_US   (100)
 Set how many increments of the count register per uS needed by the timer code.
 
#define EIC_IRQ   (1)
 We are using an External Interrupt Controller (all pic32 devices use this mode)
 
#define PERIPHERAL_CLOCK   (100000000) /* Hz */
 The peripheral clock is required for the UART Baud rate calculation It is configured by the 'config' registers (see pic32_config_settings.c)

UART Definitions

     There are 6 UARTS available on this CPU.

We route debug via UART4 on this board, this is the UART connected to the FTDI USB <-> UART device.

Note Microchip number the UARTS 1->4.

#define UART_NUMOF   (6)
 
#define DEBUG_VIA_UART   (4)
 
#define DEBUG_UART_BAUD   (9600)
