Hi,As described in these theads (link1 link2), there is a problem in using USB3343 USB HS PHY. I want to use this phy with STM32H743 MCU, but Setting Transceiver Delay (XCVRDLY), did not help. I have generated a CDC example by CubeMXUSBx_DEVICE->DCFG...

USB Composite Device

Good morning,I need to create an USB Interface that supports two functions: Mass Storage + Virtual COM. Maybe someone has already implemented a similar solution or ST has created an example. I'm looking for an example, but i have not found anything u...

Hello, I am wanting to do a firmware upgrade on a STM32H7 processor through a USB connected to another microprocessor(Such as an Eval board). Are there any examples or libraries for firmware that will run on the Eval board which will upgrade the STM32H7?

I want to try SPL2LL-Converter under Windows - but how can I start it??? Luckily, I have Oracle JRK but it doesn't help much, because GUI is disabled (grayed)

Passing multidimensional arrays over HAL UART

Hello,I have a 246 x 3 matrix that I have filled with counter values in the below for loops. I for some reason cannot get the HAL_UART to output individual columns of this matrix. for(i=0; i<246; i++) {   for(j=0;j<3;j++)   {   Audio_Data[i][j] = c...

Reset after flashing emtpy STM32G041 always jumps to bootloader instead of application, until power-cycle.

When an empty STM32G041 (others may have the same problem, couldn'T test) is flashed with an application, an real power-cylce is needed to actually start the application. Until this power-cycle, ever reset (HW or SW) will jump to the bootloader.After...
