Metro Express - Can pins be Input_pullup?

Post by Alwaysanoob »

Hi all,

I’m new to the Adafruit Metro M0 Express. I’ve used it with a RGB Matrix Shield to run a 32 x 32 Neopixel Matrix. I’ve got some animations running well but wanted to add some buttons. From the remaining pins I deduced that I could use A4, A5 and 11. Unfortunately, when I programmed input_pullup via arduino ide they didn’t behave as I expected and I’m now wondering if their are internal pull up resistors. Is anyone able to advise also if I’ve messed up and I’m using a pin that’s already used by the RGB matrix I’d love that feedback too. Many thanks

They should. Can you provide more information on your setup. What is being wired to the A4/A5/11 pins? What is your indication they are not behaving as expected?
