Atmel T87C511x A/D Example Program

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

  • Atmel AT87C5111
  • Atmel AT87C5112
  • Atmel T89C51AC2
  • Atmel T89C5115

After configuring the A/D, the program reads all of the A/D Converter channels and outputs the converted values using the serial port.

To run this program...

  1. Select the target for your device from the pull-down list
  2. Build the project (Project Menu, Build Target)
  3. Start the debugger (Debug Menu, Start/Stop Debug Session)
  4. View the Serial Window (View Menu, Serial Window #1)
  5. View the A/D converter peripheral (Peripheral Menu, A/D Converter)
  6. Run the program (Debug Menu, Go)

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.
