Resolved! HSE is not working on STM32F411E-Discovery
I’ve just started learning STM32 and I’m currently using the STM32F411E-Discovery board. I loaded the default code provided by the Board Selector in STM32CubeIDE and was trying to get a simple LED blink working. It works fine when using the internal ...
Resolved! I2C Slave hanging after 30-45 minutes of correct operation
Hi,I have a STM32F103C8T6 configured to operate as an I2C slave device on I2C1. It operates as intended for 30-45 minutes before the I2C hangs indefinitely with a HAL I2C state code of 0x2A = HAL_I2C_STATE_BUSY_RX_LISTEN. In this state, further I2C t...
Best Practices for Low Power Consumption in STM32 Projects
I’ve been experimenting with STM32 microcontrollers for a battery-powered IoT project. While I’ve tried different sleep modes, I’m still struggling to balance performance and battery life.Has anyone here implemented effective strategies for ultra-low...
STM32F407 I2C ADDR bit clearing itself and interrupt problems
Hi, Im new to STM32 and writing a bare metal interrupt based i2c library. For some reason addr bit clears itself automatically even though im not reading sr1 and sr2. I also have problems with debug mode, if i decide to step over the function that se...
Incorrectly writing to memory?
I am trying to make a guitar loop pedal with my nucleo-l476rg board. It has 1MB of flash and I am trying to write and read from bank 2 only as it is the bank of memory I want to use for storing recorded audio. I currently have an active buffer set up...

STM32H745 is unresponsive
Hi everyone,I've built a STM32H745ZIT6-based board. The microcontroller uses the LDO to generate VCORE. The idea of this board was to build a standalone solution based on my Nucleo-H745ZI-Q project.I did prepare a very simple project, where I toggle ...
Resolved! Can't Erase Flash on STM32H5
I am trying to erase a sector of the flash memory on my STM32H503RB. I have successfully validated that I can write to the flash, but when I attempt to erase the sector that I wrote, the contents that I wrote stay the same. I have a feeling that I ...
Resolved! It's not possible to reset the FDCAN instance individually
Hi,MasterMCU: STM32H743IIQuestion:Both FDCAN channels in the MCU are currently in use. I now intend to reset each FDCAN instance (i.e., reset all its registers) during its respective bus-off event, and then reinitialize the instance. Resetting all ...
