While playing FalldownCE by Iambian, I found out that when I hold down both the right and left arrows, the ball goes right. It never goes left. I was wondering if this is just this particular program, or it's made like that. (Or I have a faulty calculator)
Doesnt sound like a faulty calculator, maybe wire length on the mainboard (connecting keys to chip)?
This is an issue with the individual program.
The keypad is accessed as an array of 7 one-byte registers, with each bit corresponding to one key being pressed or released. This means that you can access each key individually if you do it right.
However, the actual program is probably something like this:
Code:
If you wanted to make the two mutually exclusive you could do something like
Code:
Or you could store the previous keypress and, if both are pressed, use the that one.
