How to make GPIO Input and pulled up ?
I would like to configure a GPIO pin on UP2 as the INT pin for my device, which is low active.
I looked both BIOS settings and the UpDemoApp:
The pulled up option is only available for OUTPUT GPIO.
Does anyone have similar experience on GPIO configuration? Is there anyway I can configure an GPIO to be INPUT, pulled up ?
I hope it is not a limitation of UP2 board. If unfortunately so, are there any other UPboards that can support this ?
I'd appreciate for any suggestions, since I've stuck here for a long time !
