Hello,

I am trying to drive PIN on NRF51822 of my microbitv1 to drive a LED with code below :

from machine import Pin

Row1 = Pin(13, Pin.OUT)
Row1.high()

Col1 = Pin(4, Pin.OUT)
Col1.low()

But it doesn't work.

I try to use on() and off() or value() function but i have the same problem.

When i add theses lines :

from microbit import *
display.set_pixel(0,0,1)

It works, but i would like to use a function to drive Pin like on, off or value.

Thanks for your help.
