Detect USB is connected on esp32-s2
How do I detect that the native USB is connected to PC? I use deep sleep and wake up on timer. When the esp32-s2 wakes up I'd like to detect if the USB is connected to the PC.

With CircuitPython you can for a PC connect by using:
You can try the suggestion here from a reddit thread that uses usb_dev.
If the above does't work out you could set a pin alarm and tie the USB power pin to another GPIO and use it as an interrupt.
Code: Select all
supervisor.runtime.serial_connected
supervisor.runtime.usb_connectedIf the above does't work out you could set a pin alarm and tie the USB power pin to another GPIO and use it as an interrupt.
