what about the difference between RxHalfCplt and RxCplt in UART

Rose_Horse over 5 years ago

MCU:STM32F0Discovery board

Tools:STM32CubeMX+Keil5.30

Test condition: PC_SerialComm tools & FT232 chip board

After trying the HAL_UART_RxHalfCpltCallback Function, I find that this function couldn`t be used in the normal transmit in UART_Comm.

And would you tell me which condition I can use this function, just in single wire mode or the others?

It is a DMA related receive function, not related to transmits you have in flight or might want to start. The DMA can interrupt at two points, when it is half way through your buffer, or all the way...
