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
AN5185 Application note How to use STMicroelectronics firmware upgrade services for STM32WB MCUs Introduction This document describes the firmware upgrade services (FUS) available on STM32WB series microcontrollers. These services are provided by STMicroelectronics code, which is located...
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 ...
To enable the USART or LPUART to wake up the MCU from low-power mode, the UESM bit must be set in USART/LPUART_CR1 before entering a low-power mode. AN4991 - Rev 7 page 4/16 AN4991 How the USART/PLUART wakes up the STM3...
If you are using a STM32H563 device, the process is the same but you have to use this default folder: STM32Cube_FW_H5_V1.0.0\Projects\NUCLEO-H563ZI Required tools STM32Cube_FW_H5_V1.0.0 [1] or upper STM32CubeProgrammer[2] Software programming tool for STM...

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
