I'm having trouble with an Optrex 4x20 LCD module. I have had no problems
with the 2x20 with a very similar program. It seems to ignore all "0"s in the
text string. This is using the LCDOUT command in PBP. I tried slowing down the
data with the defines, but it doesn't seem to help. If I put a pause in the main
loop, so that it can't refresh the screen data as fast, then it works... for a
while, then ignores the zeros again. Does the same thing weather in 4-bit or
8-bit mode. Strange... and frustrating! Anyone have any ideas?
