Unsure how to set up UART interrupt handler with RTOS

Other Parts Discussed in Thread: CC3200

Hello,

I am working with the CC3200 MQTT client example from the SDK. I'm trying to set it up to receive characters through the UART when the UART RX interrupt is triggered. Since I'm new to RTOS I don't know how to set up the interrupt handler or register the interrupt. If someone could show me an example of how to do this that would be great.

I tried using UARTA1 but as soon as I set up this UART I get sent to FaultISR(void) in startup_ccs.c. I didn't use interrupts this was just normal setup in uart_if.c. I thought it could be that the project was using LEDs on pins 1 and 2 so I disabled all the led functionality but its the same result. What causes this fault?

Regards,

Andrew

I basically need to know everything needed to set up that interrupt, like if i need any extra includes etc.

Hi Andrew,

To register interrupt handler you need to call osi_InterruptRegister() remaining setup will be same as non-os scenario. For other UART related set-up please refer e2e.ti.com/.../1571984

Thank you, I was also getting a bus fault because I had missed this line: MAP_PRCMPeripheralClkEnable(PRCM_UARTA1, PRCM_RUN_MODE_CLK);
