I connected my thumb joystick to the ADC pin of a LPC1769 board, and used the pin to read the value of the joystick. The value I read will change according to how i move the joystick.However,if i move it to the right, the up value changed. why? is it because my joystick has broken? looking forward to your reply.(the other directions are all correct)
