STM32CubeIDE 2.0 release - early heads-up!

Starting from the release in November 2025, STM32CubeIDE and STM32CubeMX will be available exclusively in their standalone versions. STM32CubeMX will no longer be integrated inside STM32CubeIDE. Instead, the two tools will be interoperable in the sam...

Resolved! The build button is greyed

Resolved! How do I configure OCTOSPI2 to use a W957A8MFYA in STM32CubeIDE, the settings are not at all clear unless there's a help file that explains the settings somewhere.

Resolved! Remote debugging on STM32Cube IDE

Hello,I have a Nucleo L476RG development board which I would like to remotely debug from a local PC which is running windows 11.I have connected the nucleo board to a linux machine (Ubuntu) and have started the ST-LINK_gdbserver application from /opt...

Resolved! Unit test: access code in one project by another project in the same workspace

I want to setup simple unit testing using something like tinytest or minctest running on the target processor. The idea is to have the application project and a test project in the same workspace. The test project will only implement a UART for repor...

Resolved! Hello, i have on my table the STM32L476 Nucleo-64 board and i installed for the first time the STM32CubeIDE. Do i have to install all STM32L4 available MCU package release versions or do i only need the latest version and ignore the older releases?

Resolved! Please help with porting this arduino library. I have to use HAL_I2C_Master_Transmit and HAL_I2C_Master_Receive to write to an i2c and I have no clue how to do.

I have this functions to work with:void write8(uint8_t reg, uint32_t value)read8(uint8_t reg)I am a newbie when it comes to c programming and have little knowledge when it comes to registers and how to write and read them. Right now the functions loo...

What does the key symbol mean on top of my source folders?

Thank you

Ceedling test framework fails to compile mock HAL libraries when working with unit tests. I was wondering if there are any additional configurations to the project to make this work. I have attached the test file and the terminal output to this question.

I am trying to set up an embedded test framework in STM32 Cube IDE. Ceedling framework works properly when there is no dependency on external libraries. However, when trying to mock any HAL library the compilation process fails. Thank you

I'm using STM32F446RE with STM32Cubeide. After I run my project (in cubeide) STM32F446RE board reads sensors and runs motors. But after I plug out the board and replug it. STM32F446RE does not do those things. Am I loading the code to wrong place(RAM).

I'm new to Cubeide pls give detail to solution.Thank you so much.

STM32 Multiple Buttons ADC Read Through One Pin With Software Button Debounce

In this tutorial, STM32 MCU is used to read the status of 3 buttons using only one pin that is configured to do analog to digital conversion continuously to read the voltage variations of a voltage divider circuit over DMA. Software button debounce a...
