UART DMA check if a byte received

Hi All,

 

Which flag in the UART DMA can be checked to indicate that I received a new byte. I also would like to check the DMA of my UART while its receiving, and if I receive a special character say '\r',I want to start processing the received buffer and reset dma. I am using the HAL library. Is it possible to do something like RxQuarterCplt instead of HAL_UART_RxHalfCpltCallback?

 

Many thanks
