Hello,
I am a student and currently working with AT89C2051. I'm new to this microcontroller. I,m using it in a circuit in which I need to compare a variable analog input to reference voltage using analog comparator of AT89C2051. I need to perform some operations in accordance with the logical output of comaprator. But I've stuck on it and don't know how to use this analog comparator. Please provide me the complete details/ C-code to perform this ASAP..

Hello,

The first thing to do is to read the data sheet, you can find it in the ARM website:

If you make a search on the web with the key word: "AT89C2051 analog comparator" you will find a lot of things.
