UART interrupt status

Postby coder55 » Wed May 09, 2018 7:24 am

Hi,

I'm trying to configure my board to handle a UART event once my given rx fifo threshold is reached. However, I also have a pattern recognition interrupt enabled. I was wondering how to tell inside my interrupt handler whether the interrupt came from the threshold or the pattern recognition. Any help would be appreciated.

Thanks

You mean your event handler? From event type UART_DATA vs UART_PATTERN_DET

I see. So I know that I can get UART events from a UART event queue and casing on it. I'm actually trying to register an ISR so that I can handle the RX Threshold event ASAP. Do I still look at the same event queue to see what caused the interrupt?

I actually wanted to install an ISR to process it faster. Should I pop an event from that same event queue inside the ISR?
