MKL17 LPUART INTERRUPT ENABLE

murraykevin — Mon, 11 Apr 2016 14:55:46 GMT

I am trying to enable the interrupt to fire on the Rx line of the LPUART0. I have enabled the LPUART0 Module as well as the clock source in SIM I have configured my pin and am able to use a polling communication successfully. I have enabled the RIE bit in the CTRL register and have created the function

void LPUART0_IRQHandler()

{

//IRQ code

}

What else and i missing to get this interrupt to fire.

Thank you for you help

You will also need to enable it in the NVIC_ISER. The bits in that register correspond to the IRQ number of LPUART0, which would be 12 for the MKL17. The priority is set in NVIC_IPR3, bits 6 and 7 (00 = highest, 11 = lowest). The ARM M0+ manuals give much more info about the NVIC than the Freescale documentation. Those can be found on arm.com.
