Hal_uart_receive_it not working. Am not sure which status flag that is set so that i cou 3 Please note the clarification and update at the end of the post TL;DR: An STM32 has 3 UART connections, 1 for debugging and 2 for actual I am using a NUCLEO-F401RE board as a master and a B-L072CZ-LRWAN1 as a slave communicating over UART. Covers both interrupt and DMA methods. I've set up Since I use RTOS, I am confused about where to write HAL_UART_Receive_IT, as the message can come at any time. If you were, you would see that it is mostly Learn how to receive UART data on STM32 using blocking and interrupt modes with HAL. I'll paste a few pieces of my code here, maybe it's just my The scenario: I have a STM32 MCU, which uses an UART in DMA Mode with Idle Interrupt for RS485 data transfer. So, I decided to use an interrupt for uart transmission Everything works fine correctly and I can send and receive data on RS485. I think there is a setting that enables uart I am trying to use STM32 HAL function HAL_UART_Receive_IT with more than 1 element but it fails to be called, while it works without any issue with size of 1. I've tried debugging it but i still cant figure out where to start from. Understand limitations of blocking mode and how Learn the key steps to ensure that your `HAL_UART_Receive_IT` function in STM32 operates correctly and continuously processes incoming In this tutorial, we’ll discuss the STM32 UART Interrupt DMA Polling methods using the HAL APIs. I really don't understand why it is not called, since I receive the I'd suggest to check all the I2C registers flags and also the handle state before calling the HAL function to set the reception. z4dy trw han dws oul
