Atmel AT91SAM7S A/D Example Program

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

  • Atmel AT91SAM7S32
  • Atmel AT91SAM7S64
  • Atmel AT91SAM7S128
  • Atmel AT91SAM7S256

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 device (Options for Target - Device)
  2. Build the project (Project - Build Target)
  3. Start the uVision Debugger
  4. Click the Serial #1 tab
  5. Click Go or Run (F5)
  6. 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.
