hi,
I am using PIC18f46J11 and PIC18f24j11 (both are same) pic micro controller ,

I write a code in Both C & Assembly language to interface a LCD.

I am using local LCD and other is FOR DATA LCD .

But it not Initialized or display anything on LCD Display

Both LCD pin Configuration and VCC supply voltage is different Local is work on 5 V and Other one is work On 3..3V

When i used local i gave my data and Control pin On PORT D * B which have 5V Tolerances.

I attached My simple schematic also in .RAR 7 ZIP format.
I also Used PMP Mode of PIC18f

All are simulate and working properly.also data and command are coming on port with delay.

But i am stuck where i am goes wrong.

Please guide me....

Regards,

Heena.

Sir/Madam,
Both the zipped files contain same files. Two C source files - first one prints two characters - '1' and 'E'. Second one prints 'E' and 'G'.
I am very eager to see those "Data LCD" and "LOCAL LCD".
Please give some more details.
