I don't know the length of the received data.<BR />I know I can use the idle length but it's not precise enough.<BR />Thought I could use an unused DMA channel triggered by kDmaRequestMuxLPUART1Rx which will write the value 0 to the counter. If nothing is received, the counter will count up to the set value and the timer will interrupt, which will mean the end of the transmission. Could it theoretically work?</P> Mon, 08 Aug 2022 16:22:26 GMT https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/RT1060-Another-solution-LPUART-DMA-Rx-timeout/m-p/1502705#M20939 Wielebny 2022-08-08T16:22:26Z https://community.nxp.com/t5/i-MX-RT-Crossover-MCUs/RT1060-Another-solution-LPUART-DMA-Rx-timeout/m-p/1505231#M21039 <P>Hello<BR />I hope you are well.<BR />To count the received bytes which counter are you using?
