By inspecting its source code, you'll see it calls huart->RxState= HAL_UART_STATE_READY; before returning. Just manually set huart->RxState = HAL_UART_STATE_READY; So long as you know you have properly stopped the interrupt-based receive in the middle of its processing, this is perfectly valid. Web当第一次调用HAL_UART_Transmit_DMA()时,串口处于READY状态,于是进行DMA传输, 注意,在DMA传输过程中,会将串口从READY状态改为发送BUSY状态(软件修改):huart->gState = HAL_UART_STATE_BUSY_TX; 但是在DMA完成本次传输工作以后,并没有将串口从发送BUSY状态改回READY状态 ...
