It is working perfectly in PROTEUS.
My problem is that i want to calibrate it i.e. if the input voltage is1v, instead of showing 1v in the LCD op i want to scale it and show 1V*some constant (say 500) and display it. Can any1 please mention the changes in the c code to be done inorder to achieve this. I hope you get the problem. I am a novice in C language and i reallyneed your help. It is a little Urgent.
Thankyou
