WebThe STM32 USART_Irq example program shows how to configure and use the USART1 of STMicroelectronics STM32F103xx microcontroller in interrupt driven mode. The configuration of USART1 is 9600 Baud, 8 data bits, 1 stop bit, no parity and no flow control. Retargetting is used to read a character over the serial input and to print out a string to ... WebMar 6, 2024 · The new FreeRTOS for STM32 recommend to use signals as faster and simpler alternative to Semaphores, especially for the interrupt synchronization with a task. Here is an example code for a button debouncing. It is basically a same thing like dealing with the ADC hardware: in the interrupt routine, send a signal to the task with the …

Modify code to use my own function for starting Rx and UART IRQ handler, where I could handle my buffer freely. Of course, I could refer to the provided HAL code on how to access UART registers. Actually you have to add ''USART1_IRQHandler'' in your code to use interrupt mode.
WebJan 6, 2024 · void USART1_IRQHandler(void) is the actual interrupt handler that gets executed by the CPU when a USART1 IRQ is triggered. It delegates the actual work to the STM32 HAL by calling HAL_UART_IRQHandler(&huart1);.. That HAL_UART_IRQHandler is the generic IRQ handler for all UART interrupts, which is why it takes a UART handle …
