Hey,

I tried to use UART DMA on lowest level (using only registers, because of performance reasons), which also works. But I cannot change the idle time of the UART DMA. It seems that the idle time is fixed to 185 bytes. I have activated this idle time by setting UHCI.uart_idle_eof_en, but did not found anything related to change the idle time to my use cases.

Best Regards

Problem solved - Never searched in UART struct for something related to this (UART.idle_conf.rx_idle_thrhd).

Hi Trawgz,

would you please share any example on how to configure UART with DMA

best regards,
