storage.enable_usb_drive()Behavior
this code should enable usb drive if the button connected to row 0 and colum 0 is pressed on boot but its not working as expected. It works fine with Adafruit CircuitPython 8.0.0-beta.0-13-gaa5f892a1-dirty on 2022-08-26; Waveshare RP2040-Zero with rp2040 but not with Adafruit CircuitPython 9.1.0-beta.2 on 2024-05-15; Waveshare RP2040-Zero with rp2040.
To detect the press in boot.py I need to change the code to that:
if event:
if event.released:
if (event.key_number == 1):
print("Enabling mass storage on boot")
storage.enable_usb_drive()So I need to detect the release of button 1 to check the press of button 0. If I read events three times, it shows 3 releases of button 0, 1 and 2 even if no button is pressed.
