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 and the other one for the timer overflow, also known as period elapse...

Every STM32 MCU comes pre-programmed with a system memory bootloader stored in the internal boot ROM (system memory). Its main purpose is to download the application program to the internal Flash memory through one of the available serial peripherals on the target device (e.g. ...
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 i...

It would be possible to use the STM32 SDMMC drivers since SdFat supports general block devices. Unless you do huge transfers, performance would be poor. There are lots of problems with the STM32 SDMMC controllers. Many variants have serious errata. Even the newest versions in STM32F7 and ...
in order to use a GPIO pin as an external interrupt, we must set it in the SYSCFG register. This process is a little involved. To find an another article dedicated to this, seeHow to select a GPIO pin to be the source input of an external interrupt in an STM32F407GG Boa...

First off, put all of your library .C & .H files in the project directory and use #include "stm32f10x_ .h" instead of using the path #include <stm32f10x_ .h> method. (this way all of your source is in a single directory---and it is less confusing on how to set it up '...
Bob Benjamin5 年多前in reply toManu Abraham TI__Guru**113765points Hi Manu, I'm going to guess that you might be making an RTD measurement or possibly some measurement where the IDAC generates a reference voltage connected to REF1. It doesn't matter if you use REF1 or REF0, but you...
