Increasing the Number of
Points to 80 makes the
Sine Waveform smoother
At this point the firmware is performing a troubleshooting loop on the digital-
to-analog conversion. You can now scope the output of the DAC module to
see the actual waveform as it approximates a sine wave analog output. To
stop the loop, click the STOP button. If you want to make the waveform steps
smoother, increase the number of points to 80 and press <Enter>. Then
recompute the 80 point sine wave by selecting the Sine Button. The sinewave
changes to the one shown in Figure 3.9.

The PICDEM™ MSC1 includes a Code Generator that will write an initializa-
tion assembly code file corresponding to the selected configuration.
If you want a Configuration Word different from the PICDEM MSC1 configura-
tion, you will need to turn off communications between the Evaluation Board
and the GUI:
Note:
The Prescale values are grayed out when the timing loop is active.
While the timing loop is active, you cannot change parameters. To
change any parameters, you must stop the loop by clicking the
STOP button or the EXIT button.
