hi all
recently i wanted to drive a 2x16 LCD module. i used RA0:RA4 as a 4-bit data bus and connected RS, E pins (on LCD) to RA4 and RA5 respectively. PBP compiles it with no errors or warnings. but neither in real world nor in proteus VSM, LCD doesn't work.
i attach all of files here.
where is the problem?
with best regards.
