Sorry about the HTML message. I just usually Reply someone's message and it sets it to the format the sender. However if I don't then it defaults to HTML. Fixed sorry. I'm trying to hook up an ADC sensor that will read a differential signal. Though I've gone through the Data Sheet for my 16F877. I can't seem to get it to read correctly the inputs. Infact I didn't get it to work at all. What are the steps I'm supposed to init the ADC and then how do I wire the Differential Inputs on my Controller. Thanks for the Helps Darren King
