I want use this mcu STM32L052T6Yx to communicate via usb (virtual port com ) whit pc (whith linux system operativ).THE power supply of mcu is 3.3v, can I problems if i directly connect PA11 PA12 PIN to the pc usb (common ground)? , moreover on pin...
Hello,I am new to the forums here! Can STM32L452RE support a combination class of HID and USB Audio Class over USB 2.0 Fullspeed?Ideally, I'd like to read and send microphone data (or any sensor data for that matter) connected to STM32L452RE over USB...
I have a rather strange request, but I am communicating to a Digital Potentiometer (AD5227) over SPI. The chip has 64 available positions, but can only increment or decremement its position by 1 for each clock cycle. To increment by 1, a 1 is place...
Good evening guys, I have an educational project for the USB protocol on the stm23f407 discovery board I made the project on two sensors and each sensor is written to a flash drive on a separate usb_otg_host port because the stm32f407 discovery board...
Hello,In my project I just sometimes need to read ADC values. I figure I could simply connect two of my signals to ADC1 and ADC2 respectively.What it strange that it does sometimes working, but sometimes it is stuck at constant value ( maybe first re...
Hi support,I am trying to have STM32H755 boots simultaneously with following use case and seeing that CM7encounter an infinite loop execution at 0xa05f0001 for some reason. Could someone help me tounderstand why this is happening and what is wrong wi...
