How to unbrick an STM32H7 after setting the wrong power mode (SMPS/LDO)?1. Introduction Depending on the application, the user has the choice between SMPS and LDO power supply.Each power supply has its own advantage and disadvantages, the user decid...
How can I use STM32CubeMX to configure HSE (high-speed external oscillator) or LSE (low-speed external oscillator)? The STM32 MCUs support several possible clock sources, several internal oscillators, and two external oscillators, which require exter...
How to use STM32 HAL UART driver API and Callbacks?What are the callbacks involved in UART TX / RX?How are these callbacks called?Why is the callback not called? 1. STM32 HAL UART supports 3 modes for transmitter (TX) / receiver (RX) Polling mode (no...
How can I configure the internal voltage reference on my STM32 microcontroller using STM32CubeMX? The voltage reference buffer embedded in most STM32 devices serve two main purposes: 1. used as a voltage reference for ADCs, and DACs 2. used as a volt...
How to export a project configuration to a compatible STM321. Introduction For various reasons, a particular STM32 part number selected for a project may not be available in the desired time frame. In this case, you will then need to find a compatibl...
How do I remap an alternate function from one GPIO to another using STM32CubeMX? Most of the alternate functions on STM32 Microcontrollers can be remapped to other GPIOs. Refer to the product's datasheet for the alternate function mapping option...
How to compare different STM32 part numbers using the cross selection tool of STM32CubeMX?ST users often ask how they compare different STM32 part numbers. This can be done using STM32CubeMX (or STM32CubeIDE which integrates STM32CubeMX). 1. Procedur...
How to find compatible devices for an MCU from ST products portfolio to work with? This FAQ answers the question: how to find compatible devices for an MCU from ST products, by describing two methods using ST tools. Here is an example using STM32G473...
Currently the graphical examples are only provided as "Demonstration" or "Hello World" in the Cube Firmware packages. But these examples do not rely on a STM32CubeMX project file (i.e. *.ioc file) which requires the user to manually configure new per...
