"WebMay 20, 2016 · Firstly, tx_timeout is 0 and most code examples are non-zero. I do not know the side effect. Secondly, HAL_UART_Transmit () is a blocking call and it is not advisable to use blocking calls inside an interrupt. So, I decided to use an interrupt for uart transmission HAL_UART_Transmit_IT () instead of a blocking call. Here is the modified code; " - Hal uart timeout

WebOct 28, 2024 · The normal case can still be that the data doesn't fill all available space. 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.

WebNov 10, 2024 · Hi @zfields,. The HAL_I2C_Master_Transmit() function is designed so that the timeout value corresponds to the duration set by the user to ensure that the system don't hang during the transfer. The timeout value does not correspond to one character but for the full communication and it should be computed by the user depending on the … Sorted by: 1. Most likely the other side is not configured for hardware flow control, so the STM32 never sees the clear-to-send signal being set. You could disable hardware flow-control on the STM32 UART, or configure the other side to use hardware flow-control. (And ensure all the RTS/CTS signals are connected.)
