Digital-to-Analog (DAC) Module Configuration
3.1.1
DAC Module Setup
In this project you will configure a digital-to-analog conversion that requires
stepping through a series of digital values to produce an analog sine wave
output. You can utilize the Arbitrary Waveform feature of the PICDEM ?
MSC1 to set up the conversion parameters and exercise them in a looping
environment to allow scoping the output of the DAC.
In this example, you will perform the setup tasks to:
? Configure a single digital input/output line
? Exercise a conversion loop to allow scoping of the DAC output
? Save the configuration file to be used in your application.
3.1.1.1
Enabling the DAC Module
1. Start the GUI software by selecting Start → Programs → PICDEM MSC1,
or you can double-click the PICDEM MSC1 icon on your desktop.
2. Select the Pull-down menu Options → Enable Eval Board to begin com-
munications between the GUI Control Panel and the PICDEM ? MSC1.
3. Select the Input/Output tab on the GUI Control Panel, as shown in Figure
3.1.
