i have written a code in mikro c without using lcd library, my lcd has a ST7066U driver and i have written for 8-bit interfacing. now i have test the code in proteus 7 but nothing is showing.
Note: i am not using lcd library given in mikroc because the code is for HD44780 and for 4-bit. Is there a library for 8 bit interfacing? And is ST7066U is fully compatible with HD44780?
Please help me, can anyone check my code and tell me about is there any wrong with the code;
