Hi folks, I finally have the AD working and I am measuring the output from 0-5v. I was under the opinion that the output would be linear, that 0v give 00000000, and that 5v gives 1111111111. Which it does. It's the intermediary measures that bug me. I was thinking that 2.5v would be approximately half way down the scale which would be around 506 which is the mid point between 0 and 1024. But I'm getting:
102/0.1v
700/0.5v
918/1.2v
984/2.0v
996/2.24v
1020/4.25v
1023/5.0v
This is not a linear progression.
