In this demonstration, we use the STLINK VCOM Port connected to the MCU's USART3 (figure 2). Furthermore, we use the TIM2 and the board’s user LED (figure 3). Two callbacks are registered: one for the UART_Tx
In this code example, it reads the first backup data register to see if it was written previously and if not, it will unprotect the backup domain and write to it. Once the code is executed the first time, we will do a reset of the STM32 using the button connected to the reset input...
We can call the STM32 HAL functions (e.g. HAL_UART_Transmit), but sometimes it’s easier to use the standard C library functions printf, scanf, and so on. To do that, we need to re-write the underlying functions.Note: the code for this section is taken from Carmine Noviello’s ...

If you plan to use the Registers instead of using the library functions, you need to give 8 bit address,0 1 0 0 A2 A1 A0 R/W. HOW TO Connect LCD to PCF8574 As shown in the first picture, the first pin of the device isVsswhich is pin 1 of LCD. So all you have to do is ...
The STM32 is a powerful 32-bit Cortex-M microcontroller that is extremely common in embedded applications. In fact, it’s one of my favorite microcontrollers, especially for non-wireless commercial product applications. They come in a wide variety of
4.1.) In Middleware -> FREERTOS -> Configuration -> Task and Queues double click the defaultTask and set a stack size of 3000. It has to be greater than 10.000 byte (3000 words * 4 byte = 12.000 byte). 5.) In Connectivity choose the UART / USART that you want to use. 5.1.) ...
