I m using 89c52 to operate graphical display(128x64).
i use keil for coding the IC.
here i post my program that is not running.
Can any one help me to find out that what is the problem??
program......>>>>>
#include<at89x52.h>
#define port P0
sbit LE=P3^7;
sbit EN=P3^6;
sbit RST=P2^0;

no sir, 12v is main power supply to my project. my controller operate on 2.5v, which should be operate on 5v. so problem is in config bit.
we use voltage regulator ic that conver 12v to 5v. so if we give 12v then IC convert it to 5v, similarly
if we give 5v then ic convert it to 2.5v and on...
i m using pic 16f887 controller. I hv problem with configuration bits. my project must work on 12v but currently it is working on 5 v. so can anyone help me to set configuration bits.
i use external crystal of 10 MHz.
i can not identify my problem, i think it shold be in configuration bits...
i want to use zener diode in place of optocoupler for saving space... i m using transistor(NPN) and zener diode before transistor. i also pullup supply by 5 v. so is ground makes transistor on?

this is image of conection i m making.
I want to use CAN serial communication in my project. For that which microcontroller i should use that can competible with CAN and can available in market easily..
