Atmel AT91M55800A A/D Example Program

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

  • Atmel AT91M55800A

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 from the pull-down target 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.
