Resolved! EP0 IN transfer times out
For learning (and suffering) purposes I am trying to write my own USB Driver in device mode. Right now I am just trying to successfully enumerate the device. So far I am able to read SETUP packets but when writing to EP0 (IN transfer) the requests se...
QSPI unexpected clock behavior STM32H723VGTx
Dear Community,for my application I use the STM32H723VGTx where I'm using the OSPI interface as a SPI and QSPI to control a external sensor (MCU SPI master, sensor SPI slave). Now I face some issues with this communication interface, for debugging re...
Uploading option bytes over DFU
Hi, I have a custom board using STM32G431CBU6. I am using `dfu-util` to upload firmware and option bytes. I don't have any problem reading/writing flash area with DFU, and I can read the Option Bytes area with DFU, but when I try to upload a valid op...

variable phase shift between two PWM signals
Hi,I am trying to create to PWM outputs with a variable phase shift between them. They are of fixed frequency, 50% duty and exactly the same shape but with variable phase shift. I need to dynamically change the phase shift between them as a control p...
STM32G051F8P6 GPIO state during reset
Hello,I have some strange behavior with a circuit. My understanding is that the GPIO should be configured as an input at power up, however, I am seeing a brief flash on an LED during power up and Power down (images attached showing circuit and the 3...

bug with USB_CHEP_RXTXBD count on stm32H5
Hi, I made an asm soft for the H5 (works well with H7,G4,G0,F7,F4,F0). That software configure the stm32H5 into an USB CDC device. When my frequency of my main clock, apb1 and apb2 is below 220 MHz, my software works well but when i put my main clock...
