What model PIC did you use?
PBP version?
What CONFIGs did you use?
What code do you have so far?
Do you have a schematic of your circuit?
Robert
That's a pretty far reach.
Because your screen dimensions weren't evenly divisible by eight.
Chuck it and start again :D
i have pic model 16f628A.
PBP version is beta 0.1
yes i have Schematics both of display circuit and controller circuit.
but i use 24C04 in place of 24C56.
all things are these attachments.
i use hex file for programming code.
Attachment 7132Attachment 7133
plz help me. because after done the all things nothing be shown on display.please help me.
I'd start by updating. lolQuote:

This works:

but if it didn't, it would be easy for everyone to help.
The reason I find this funny, is total lack of information
like "I have a problem with my kite, it doesn't fly".
Unless you know you can use the EEPROM you did,
that could be a problem. It would have been for one I wrote.
So it would help, for example, you communicated that you do,
or don't know it's ok to substitute that EEPROM.
If it's a personal project, check Microchip samples won't provide the right one for free.
Make sure you have 5v on your circuit to begin with. LM7805 could easily be placed backward with this schematic.
