Analog to Digital Converter Example Program
===========================================
Project: ADC
Author:  Brian Clough

This example program shows how to configure and use the 8 bit
A/D Converter of the following microcontrollers:

* Analog Devices ADuC7020, ARM7-TDMI Microcontroller
* Analog Devices ADuC7021, ARM7-TDMI Microcontroller
* Analog Devices ADuC7022, ARM7-TDMI Microcontroller
* Analog Devices ADuC7024, ARM7-TDMI Microcontroller
* Analog Devices ADuC7025, ARM7-TDMI Microcontroller
* Analog Devices ADuC7026, ARM7-TDMI Microcontroller
* Analog Devices ADuC7027, ARM7-TDMI Microcontroller

This program reads all available ADC channels, and stores the 
converted values in an array.

The user can view the data from the first two channels, in the 
pre-configured logic analyzer widow.

To run this program...

1. Select the device from the pull-down target list
2. Build the project (Project - Build Target)
3. Start the uVision Debugger
4. Open the Toolbox (View - Toolbox)
5. Open the Logic Analyzer (View - Logic Analyzer Widow)
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.  礦ision3 users may 
enable the built-in Logic Analyzer to view, measure and compare
these input signals graphically.
