Access: Portenta H7 Breakout Board - GPIO PIN

Hardware Portenta Portenta H7
1

Hello,

I use a Arduino Portenta H7 with breakout board and Micropython.
How can I access the GPIO pins (0-6) of the breakout board in Micropython?
I wrote a short test program, which works fine for an output pin on the Portenta H7. I tried with maschine.pin('GPIO_0') but without success.

Thanks.

import time, machine, pyb

pin = machine.Pin('PH15', machine.Pin.OUT)
led_red = pyb.LED(1)
led_green = pyb.LED(2)


while True:
    pin.high()
    led_green.on()
    print('High Level activated')
    time.sleep(10)
    led_green.off()
    pin.low()
    led_red.on()
    print('Low Level')
    time.sleep(4)
    led_red.off()
2
