    void delay(unsigned char count)
    {
    unsigned char i;
    unsigned int j;
    for(i=0;i<count;i++)
    for(j=0;j<1275;j++);
    }
     
     
    I need explanation for this.  How much delay will be introduced by this function and why?? Why we are using 1275 only why can't another value??

    if you simulate this function it will give you delay in multiples of ms

    to generate perfect delay use inbuilt timers of 8051

    First of all as you named to the files is wrong it doesn't affect on your programs but main.h file that is header file should contain all declaration part that is variable declaration and function. and main.c file should contain all function and same in case of lcd.
