Hello,
I need to connect a button to GPIO-2 pin and I am trying to pull it up.
According to fex file specs, I am adding following line
gpio_pin_3 = port:PB03<0><1><default><default>
to [gpio_para] section.
PB03 is supposed to be pin #11 on GPIO-2.
import time
import A13_GPIO as g
BTN = g.PIN2_11
g.init()
g.setcfg(BTN, g.INPUT)
while True:
time.sleep(0.1)
result = g.input(BTN)
print time.time(), result
It reads zeros only and does not change when I press the button.
I can pullup this pin by using an external resistor, but it would be nice to use built-in functionality.
I have A13-Olinuxino Rev. C board.
Does anybody have a working example of how to pull a pin up via fex file?
Thank you.
