The default baudrate is set to 9600 b/s. While testing the library I tried different values from 4800 to 115200 b/s and it worked fine. Now, let's proceed to the source file MT_STM32F4xx_USART.c. All the functions needed for USART working are exactly located here. The first is initialization function: MT_USART_Init();. In STM32, UART is the most common mode of communication - it receives one byte at a time, and we can use polling, but for some data sent in a fixed time, polling is sometimes not flexible enough. You can also use interruption, such as interrupting every byte once, to consume system resources.. For example, take BlackPill board with STM32 MCU and a small firmware that checks the secret key (transmitted via UART) and either blocks the device (lines 30-37) or performs the basic In the interrupt vector, there is a 0x04 shift from the beginning of the flash (ResetHandler @ 0x0800 0004)..

Abstract: This chapter illustrates three different program models, HAL library polling, interrupt and DMA with the example of serial communication. In serial communication, data is transmitted in characters, and each character is transmitted in bytes. It always starts from start bit and end with stop bit.. Setting up UART serial communication is useful for any type of device-to-device (point-to-point) communication. Additionally, I will not be using interrupts and the example will be set up as a simplex system that transmits in one direction only (towards the PC). The stm32f4xx_hal crate to import the STMicro STM32F4 …. inside the examples there are several examples how to use interrupt with this peripheral, I took the xuartlite_intr_tapp_example.c file.
