TI MSC1200 A/D Example Program

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

• Texas Instruments MSC1200Y2
• Texas Instruments MSC1200Y3

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. Open the Toolbox (View - Toolbox)
5. Click Go or Run (F5)
6. Click on the Toolbox buttons to change input voltages

The ADC program reads all eight analog inputs of the MSC1200 and outputs the values along with other A/D relevant information via the serial interface.

This example shows a simple method to convert the A/D HEX values into a voltage value that is more readable. The algorithm uses only long arithmetic and avoids any loss of precision as it would be the case when using single precision floating point arithmetic.

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 a 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.
