Dear Mr. Sutar,

Thanks a lot for your reply.

I can try the serial port stuff only tomorrow since it is 07:00PM here and I am at home. I will let you know the results.

I have tried writing a small program that does nothing else but initialises the LCD, creates two variables of uchar type one in data and other in code and then sends these variables to LCD. Like this...

void main(void)
{
    unsigned char data ddata='L';
    unsigned char code cdata='M';
    unsigned chat data temp;
    
    init_lcd();
    temp=ddata;
    lcd_data(temp);
    temp=cdata;
    lcd_data(cdata);
    while(1);
}

Upon executing the above program the LCD shows 'Lb' I tried changing the varible values to PQRsT almost everthing but in all cases the byte in data segment is displayed correctly but in code segment is not displayed always 'b'.

Here is the partial schematic of my board.



Thanks & Regards,
