Hello!

Why this code is not working? The proteus simulation is also not working.
I have attached the mikroC Pro project files and proteus design. I am using 4 MHz Internal OSC.

Thanks

Hi;
I do not know this PIC, but the simulation shows that the internal oscillator does not working: all output pins grayed out, and the program counter (PC) is not increasing, remains zero. To see this pause the simulation and examine the PIC CPU registers debug window.

Revise also the config settings in the MikroC: Project > Edit Project.

My advice is to use an other but well-known processor, or try for the first time in a very simple program such as a blinking LED.

The C program was not examined (not enough time), but attached a 2WIRE LCD interface project, made by me in 2007. That said, it was written in assembly language, but maybe this also helps

edit
Sorry for the wrong attachment. Changed.

another processor PIC16F877A was also used. It had the same result, ie., blank display but pins were not greyed out.
 

if u are using PIC16F877A then ADCON1 = 06;

i worked on HITECH compiler not on mikroC

i have LCD code for PIC16F877A for HITECH compiler

hope this helps u

Thanks. I use both mikroC and Hi-Tech C pro. I will try your code.
 

I want to use any PIC and 74HC595 to interface LCD in serial 4 bit mode.
