this is the lcd display program
PostPosted: Mon Mar 17, 2014 6:10 am     Reply with quote
i have no error & warnings.... but the simulation is not come... can you help me ?

1) nobody here can fix PROTEUS problems...so build real hardware.You should use a current PIC, the 877 is almost 20 years old, there are cheaper, better PICs to use.

2) start SMALL ! About 95% of your program is commented out or NOT required so get rid of everything that is not necessary,really start over.

3) I can't follow what you've done..it's way to 'complicated' a 'mixture' of code segments ,none will really work as a 'program'.

Get a PIC and cut the simple '1Hz flashing LED' program. CONFIRM that it works in real hardware.
Do NOT proceed until it does work !

THEN

cut code for the 'test LCD Hello World' program. CONFIRM that it does work in real hardware. I suggest using the 'flex_LCD driver' as it is KNOWN to work very well.

THEN

proceed with your school project.
