Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
Good evening, I need freeRTOS tick speed to be greater than 1kHz, I tried to change the configTICK_RATE_HZ parameter but get a divby0 error which I can't fix. Is there a way garanteed way to achieve what im looking for? Thx in advance
Hey!I'm working on implementing USB host functionality on the STM32U545 using the USB_DRD_FS peripheral. I've got the basic structure working, but I'm stuck at the enumeration stage, where the device responds with NAK to SETUP packets and enumeration...
Hello! This is the first time I'm using an STM32L0 (...11F4Ux) and also the first time I've tried implementing an I2C IRQ Handler. The code snippet mostly works, but there's a bug in which a READ commands sends data from the previously requested regi...
Hey everyone,I'm currently trying to integrate the STM32 FP-AUD-AEC-1 software package in a multithreaded environment (ThreadX) on an STM32wb55rev7 mcu chip. Library compiles and runs but eventually hard faults during thread initializations. Any advi...
Hi community,Before I start discussing my specific issue, I would like to know if dual USB host operation is allowed on STM32H7 MCUs. The H7 MCU has both FS and HS USB cores, and I want to configure both FS and HS as USB hosts, not using the OTG feat...
Hi everyone, my custom board previously had an STM32F746BGT6. Since we were looking for a microcontroller with a graphics accelerator, we opted for the STM32H743BIT6 (which is pin-to-pin compatible). All the peripherals work, but I'm having trouble i...
There have been previous posts about determining how the DFU serial number is formed from the 96-bit Unique ID. However, when using the ROM bootloader for the STM32F723xx MCU I don't see unique serial numbers at all. I am always seeing the same DFU...
Hi, this is my first post here and one of my first experiences with the STM32.I'm working on an STM32H7A3ZI-Q development board. I've connected an Adafruit PDM microphone to SAI1_A with clock on PE2 (SAI1_CK1) and data on PE6 (SAI1_D1). I'm not an ex...

Struggling with a really weird issue here. I'm working on a project using Zephyr on an STM32U5A5ZJT6Q. We are using an LSE-clocked LPTIM as the tick source, PM enabled with STOP0 and STOP1 modes.At some point, we started noticing random crashes, whic...
