Maxim MAX7651/7652 A/D Example Program

This example program shows how to configure and use the A/D Converter of the following microcontrollers:

• Maxim MAX7651
• Maxim MAX7652

After configuring the A/D Converter, the program reads A/D channel 0 and outputs the converted value using the serial port.

To run this program...

1. Select the target from the pull-down list.
2. Build the project (Project - Build Target).
3. Start the uVision Debugger.
4. Open the Serial Window (View - Serial Window 1).
5. Open the Toolbox (View - Toolbox).
6. Click Go or Run (F5).
7. Click on the Toolbox buttons to change input voltages.

A debug script (debug.ini) creates buttons that set different analog values in A/D channels. As the program runs, you will see the A/D input and output change.

Other buttons create signals that generate sine wave or sawtooth patterns as analog inputs. µVision3 users may enable the built-in Logic Analyzer to view, measure and compare these input signals graphically.
