We are pleased to announce that STM32CubeIDE 2.0.0 release is available. STM32CubeIDE is now independent from STM32CubeMX. With this release, device configuration, previously handled within STM32CubeIDE via STM32CubeMX, is now exclusively available t...
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...
Hello everybody,I just recently installed CubeIDE on my Mac and Windows systems. On both Code Proposals for thinks like HAL functions or user defined functions does not work. Do you know if there's a chance to change that? I already activated all kin...
Hello!I'm receiving data by UART in a ring buffer. When my buffers are lower than 256 it works, but when higher, it get stuck in the first for loop of my code.This is my ring buffer.void HAL_UARTEx_RxEventCallback(UART_HandleTypeDef *huart, uint16_t ...
Hi. I am using STM32L031 for my project. And I am using I2C to read eeprom. It is reading eeprom properly but if you see duty cycle on SCL(red one in the pic below), it is not 50%.My I2C spped is 400kHz. ON time I get is 750ns and OFF time is 1.96us....
Hello there,After an update off STM32CubeIde from 1.17.0 to 1.19.0, the compilation of my code generates a lot of undefined references in functions like HAL_Init(). Do you know how to solve this problem? All of the header files are linked in same C f...
I have a B-L462E-CELL1 board, and I have managed to compile code in STM32CubeExpansion_CELLULAR_V5.2.0 with MQTT client enabled in IAR IDE.Since IAR is not free, I tried to follow its code structure and build it in CubdeIDE.However, the CubeIDE compi...
I'm using u8g2 as a Git Submodule in an STM32CubeIDE project. It has a "sys" subdirectory that contains 87 main.c files. When I save Device Configuration it opens all 87 files, then Device Configuration Tool vanishes. Exclude from Build doesn't help....
It was programming using STM32H753.However, when the size of the program is over 128 KB, it does not work.How can we solve this?
Hi, I need to support 6 libraries for 3-5 MCUs each, and recently I have struggled to keep up.Many users complain about bugs I thought I squashed ages ago, only for me to realize that I never updated the code for that specific MCU.Is there a way to s...
I'm working on a STM32H753 (with EVAL2 eval board) on which I have connected an external QSPI Flash.Right now the CPU is @ 400MHz, the QSPI is configured in single IO (SPI) @ 12.5Mhz.I can erase, program and read the Flash in indirect mode, then read...
Hi, I'm tring to write my program on a Mikrobus Clicker 2 (STM32F407VG) from the Software STM32CubeiDE with a mac. then I create a project and connected my board on my ST-LINK/V2. I configured Pins and set As Serial Wire. and the Debug As SWD.I got t...
