WebI am new to the hal libraries (but not stm32 devices) and struggle to see howHAL_UART_Transmit_IT is expected to be used for something simple like printf over uart. Take a blocking example: void PRINT_MESG_UART(const char * format, ... ) {. va_list ap; uint8_t buffer [128]; int n; va_start(ap, format); Webstatus = HAL_I2C_Master_Transmit_IT(&hi2c1, ltc4306_Address, data, 2 ); return 0;} In the moment, when you execute return line, you pop fn function pointer from stack. i2c takes data from different place in memory and NACK on SDA occurs -> …

HAL_UART_TxCpltCallback is a callback function for you to implement. It is defined as weak in HAL and therefore if you create such function anywhere in your code without weak in front of it, the linker will pick your implementation. That way you can implement it without touching HAL code. – J_S. WebHAL_CAN_Transmit_IT and HAL_CAN_Receive_IT work with interrupts. I would suggest you find the one that is more important for you and use the interrupt on that. For example, if you'd rather receive than transmit, use HAL_CAN_Receive_IT and HAL_CAN_Transmit for the transmit part..

How to use UART to Transmit Data in STM32 - ControllersTech

WebIt is a protocol of serial communication and support both synchronous and asynchronous transmission. In asynchronous mode, a USART bidirectional communication needs two pins: receive data in (RX) and transmit data out (TX). In synchronous mode, an addition pin (SCLK) for clock synchronous is needed. In most cases, we use USART in asynchronous ... WebTo Setup the DMA, we have to ADD the DMA in the DMA Tab under the UART. Here We are doing the Transmission, so UART1_Tx DMA is added.
