WebJan 10, 2024 · The STM UART interface can only send 8 or 16 bit in one step. For that reason the HAL_UART_Transmit can also only take uint8 or uint16 chunks. If you have to send the 32 bit of a float you can pass each byte of the float and send them as single bytes. The receiver has to interpret them as a float again. WebThe DMA is different with the STM32MP1, some help with the configuring it with a UART for transmit would be helpful. With STM32CubeMX, if UART is assigned to Cortex-M4, you could assign DMA2 streams to it and got most code ready to use. I think your question is for Linux side. Regards. Actually my question is on the M4 side. Not the Linux A7 side.

Web6. You receive ~67 characters, which at 10 bits/character, is 670 bits. Given that your timeout (parameter 4) is set to 10ms or 0.01 s, the average bit rate seems to be around 67000 bit/s. My guess is that you are transmitting at 115200 baud with some inter-character delay giving an effective bit rate of 67000 bit/s.

One way is to stop receiving data based on what has been received so far, for example looking for a \r\n pattern that indicates a newline. To do this, you must examine each byte when it has arrived. The other way is to do a inter-byte timeout.
