LCD interfacing?

Hi,
I am working on LCD interfacing with C8051F005 Cygnal Microcontroller.
I am facing problem for displaing larger number(ex:4096,3996) in the LCD.

I have no problem with printing Strings.For strings i have written a function by checking the length of the string and null character.

How to send the a larger value at a time to the LCD.For this numbers(Data type is unsigned long int) also we need to write a function?

Please send me some sample codes?

Thanks,
Viswanath.
 

Re: LCD interfacing?

If you are sending these as string then it will print, if you are assigning it to any variable it will not take as the registers are 8 bit wide and the variable used is more than that. you may have to store it in terms of 8 bit in consecutive registers or location and send data to controller for printing.

Hi,
I have used a simple loop for breaking the number into individual pieces and then i have sent to the LCD with some delay.

Its worked fine.

Regards,
Viswanath.
