A/D converter - MEGA16L

2005-04-23 by Nazeer Vawda

I got the following task to carry out,and im totally lost. Its the first time im programming in AVR. Where do i start??

Write properly documented c-code to run the A/D converter in 8-bit mode on 2 channels and read values from 2 potentiometers. Use the push-buttons to select the channel (no button * off; button 1 * Channel 0; button 2 * Channel 1), and display the A/D value on the led's. Calibrate at ten voltage values and check for cross-talk between channels.

Seems like a fairly unreasonably complex assignment from the prof if you are
an undergrad. The challenge is to select and learn to use the tools.

My recommendation: use the freeware version of Codevision AVR and A/D and
libraries

Sounds like a homework problem.  You're supposed to figure these out
on your own.  As to where to start, the best place is the datasheet.
