3.1.1.2
The PICDEM™ MSC1 GUI contains an Arbitrary Waveform feature that can
be used for testing the DAC peripheral. This feature allows you to generate
sinusoid or triangle wave data to upload to the DAC. You can also load a wave
data file previously generated and saved as a text file. Wave data files consist
of integers between 0 and 255, one integer per line. Each line corresponds to
a waveform data point. Up to 80 points can be specified. If more than 80
points are in the file, only the first 80 will be used. Less than 80 points will
automatically RESET the point counter to the number of points specified in
the file. An example waveform file (ArbWave.txt) is included in the installa-
tion directory.
