#167471 - dangerous loops Responding to: ???'s previous message |
Why not format the code as code? Would it have been to easy to read?
Your only use of comments seems to be to deactivate code. Have you looked through your algorithm? You seem to assume that if you get past your first loop, you will always get an assign to "row" and "col". Is that really true? What would happen if you press a key too short time so your "col" scan doesn't see anything? You have a 4*4 keypad, but you are using all 8 bits of two ports. Shouldn't you mask away the bits that are not used? |
