We are implementing USB Bootloader for our project. MCU is STM32F779NI and we are using ST HAL libraries for our implementation. After completion of checks, control suppose to enter into callback function via HAL_HCD_IRQHandler(). Device state chang...
Designing a board right now which has a STM32G072 to have two USB Type C ports, one sink and one DRP. First chip I looked at was the TCPP01-M12 - obviously it's the one on all the devboards. using it as a sink seems quite easy, though as a source or ...
