STM32F778, VDD 1.8V, USB not working

We have a design using the STM32F778. The FS USB works fine with VDD = 3.3V. When VDD = 1.8V, the USB does not work. VDDUSB is connected to 3.3V in both cases. On some boards, the FS USB will be detected by PC as a bootloader but it does not actu...

In my project I cannot enable SysTick to save power but I have the RTC available. Now the HAL_GetTIck always returns 0 and this is bad for I2C drivers that use HAL_GetTick to measure timeouts. How can implement HAL_GetTick using only RTC?

How to set up an USB-CDC-Host and read Data from a Serial device firing values nonstop.

I use a STM32F429ZI-DISCO board that was programmed using STM32CubeMX's Code generation for a USB-CDC-Host on high speed. To generate some input data I use a Teensy3.6 as an arduino Board set up as a serial communication device. The data sent by the ...

I implemented a USB MSD using an external SPI flash device on my STM32F105 board. Windows can see this drive, format it, and use it. Besides being slow, it works perfectly under Windows.The FAT file system driver on the board can open and read file...

USB Bug Report: NULL pointer access on deInit

If a charger is plugged into the USB (rather than a computer) then USBD_MSC_Init() is not called. Consequently pClassData is left NULL. If the USB is then stopped via USBD_Stop(), then the USBD_MSC_DeInit() is called and the NULL pointer is accessed ...
