Function Documentation

uart_irq_handler()

void uart_irq_handler

(

uint8_t

sercom

)

UART IRQ handler.

Call this function from the IRQ handler for the UART SERCOM. For example, if you are using SERCOM5, you would do this: void irq_handler_sercom5(void) { uart_irq_handler(5); } UART transmssion and reception are interrupt driven, and nothing will work if this function is not called.

Parameters

sercom

SERCOM number

Todo:

Really need to refactor this so it's called from the HAL, not the app.
