Question Screen Controls

    Hello all. I am having trouble getting my keyboard to work for screen controls.

    I have connected VCC, GND and KEY pins from the keyboard to my main driver board that powers the screen. I am measuring 3.3v into the keyboard. When I depress the buttons to activate the screen controls, I am not getting any response on the screen, indicating that there is something not right. Does anyone know why this is the case? Have I made a mistake with the wiring? I really am not sure what I have done wrong.

    Here is a picture of the controller board. I've removed the onboard tact switches. I wired up wires diagonally on the pads where the old tact switches were, and measured to make sure there was no continuity between pads.

    check to see if your buttons are pulling the resistors to ground
