The functionHAL_UART_Receive_DMAis used to receive 4 data bytes. Once all the 4 bytes has been received, the interrupt will trigger and the UART Receive Complete Callback will be called. intisSizeRxed=0;uint16_tsize=0;voidHAL_UART_RxCpltCallback(UART_HandleTypeDef*huart){if(isSizeRxed==...
Hi,community We use imx6q UART port to communicate and receive information from other device using RS485,The device will always send data, we have
when the data received from the uart has transfered to the dmaCfg.rxBuf,the dmaCfg.rxHead should be increased and i didn't find the code implementing that function. what't more,the trick,as your say, is that the DMA channel for UART Rx is setup to tran...
UART data receive in AN75779 design Attachments are accessible only for community members. Log in FX3_user1301 Level 3 7 Aug 2024 Hi, I am using application note AN75779 in my design and able to stream my video. But I need additional feature of communication with FX3 and my ...
Hi: I have too many uart data to receive, and the frame length is not sure, and I do not want so many uart interrupt, so I want use DMA, but the dam
