Philips P87LPC769 D/A Example Program

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

Philips P87LPC769 
The program configures the D/A's and generates a sine wave on the DAC0 channel and a sawtooth waveform on the DAC1 channel.

To watch the effect this program has on the D/A Converters:

Build the program (Project-Build Target). 
Start the Debugger (Debug-Start/Stop Debug Session). 
Open the D/A Converter Dialog Box (Peripherals D/A Converter). 
Make sure View-Periodic Window Update is checked. 
Run the program and watch the D/A outputs change. 
When the program writes to DAC0 and DAC1 you will see the corresponding registers change in the D/A Converter dialog.

μVision3 users may enable the built-in Logic Analyzer to view and measure the digital input and analog output signals graphically.
