What am I doing wrong? Setting pins as inputs and outputs

[danielb1194]

I am trying to set pins when I press a button, and clear is as soon as I stop pressing the button, however the board turns on all leds at once and does not respond to input from the buttons.

Debugging the project leads me nowhere, as the PC jumps around the various included files.

Hi, me again.

RTFM again haha.

Hey again Andy! RTFM I did, and I know the pins are connected to the leds and the leds to VDD instead of GND, so the functionality should be reversed, however the leds are simply not responding to the buttons input.

Am I using the wrong functions? or is it that the LEDs are connected through the IO expanders??

It says there that the button inputs need to be configured with pull ups.
