USB stick enum error on STM32H7B0 board
Hi everyone: I am trying to add USB stick support to STM32H7B0VBT based board. I used STM32CubeMX to generate code relating to USB host, FatFs, and system clock. USB plugging in and unplugging can be recognized by the middleware (in usbh_core.c), but...

Resolved! STM32H7 JPEG encoding with DMA leaves empty space
I am encoding a 200x300 image using the JPEG codec available in the STM32H743. The input format is ARGB8888, with the input buffer having a size of 240000 bytes (200*300*4). As I do not know what the output size of the JPEG codec will be , I have all...
How to Reset an UART after an error
