STMicroelectronics STR7xFxx A/D Example Program

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

  • STMicroelectronics STR710FZ1T6
  • STMicroelectronics STR710FZ2T6
  • STMicroelectronics STR711FR1T6
  • STMicroelectronics STR711FR2T6
  • STMicroelectronics STR712FR1T6
  • STMicroelectronics STR712FR2T6

After configuring the A/D Converter, the program continuously reads the converted value from A/D channel 0.

To run this program...

  1. Build the project (Project - Build Target)
  2. Start the uVision Debugger
  3. Open the Serial Window (View - Serial Window 1)
  4. Click Run (F5)
  5. 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.
