Combine UART + DMA for data reception Now it is time to understand which features to use to receive data with UART and DMA to offload CPU. As for the sake of this example, we use memory buffer array of20bytes. DMA will transfer data received from UART to this buffer. ...
I have this code that initiates my UART channels with DMA at startup: if( HAL_OK == HAL_UART_RegisterRxEventCallback( m_configuration.huart,
