Hello everyone,I’m encountering an issue with the srand() function in my STM32H747 project, and I would appreciate your insights on what might be causing this problem.Hardware:MCU: STM32H747IIT6Custom boardSoftware setup:CubeMX-generated projectCube ...
I am using the STM32H743VITX MCU and TouchGFX with the display (800x480px) in a single buffer format with RGB565. The framebuffer size is calculated to be 750KB; however, the MCU does not have a contiguous 750KB region in RAM. I am exploring ways to ...
Hello,I am testing UART via a loopback test. This shows that the expected data is being sent on TX and received on RX, but the receive function always times out.This post stated to clear the OVR and RXNE flags before calling the receive function, but...
Hello,I'd like to set up a log management system that would allow me to write to both the UART and a file (NOR flash).However, I'm encountering data architecture difficulties that I can't resolve.I'll typical want to write in my file only after buffe...
I'm working on an STM32 project where I'm jumping to code in external QSPI flash (address 0x90000000) after booting from internal flash. I've configured the QSPI memory-mapped mode correctly, and the jump to the external flash works. The interrupt ve...
After updating the i2c library to the latest version, I got a write error. After reverting the library to the previous version, the error went away and the location where the error was returned is:stm32f3xx_hal_i2c.c / I2C_IsErrorOccurred()Line 7255I...

I have an older STM32 Nucleo-F746ZG and I want to try and send some serial over the ST-Link. I am in Ubuntu with VS Code. I have successfully built the project and it appears to be running in debug mode. However when I try to connect and read the ser...
I've tried to disable the XferHalfCpltCallback when using UART DMA transmit without any luck. I believe that you cannot change the callbacks, or disable them. Observations:When you call HAL_UART_Transmit_DMA(), the callbacks are set to predefined U...
HelloThis is my first post on the forum, always a happy reader in the past and happy STM32 user as well!Now I want to go a bit further then the standard IO and control. I want to implement LWIP + FreeRTOS with a STM32F7. And yes, the fresh generated ...
