Hello,
I have a question about the USB of an STM32 device. The Controller I want to use is the STM32F413VGT6.
I don't want to use the 5V provided by the USB host and I only want to run it as a USB device using a USB B Connector.
Are the following steps correct?
- I connect GND of the Connector with GND of my Board.
- I connect the Shield of the Connector with (1M || 4.5nF) to GND of my Board.
- I connect D- and D+ the following way: Dx -> USBLC6 -> 22ohm -> STM32
- The VUSB from the Connector is only connected with the USBLC6 VBUS input
My µC is running at 3.3V. Will there be any problems with the 5V USB data lines?
Thank your for any advices!
