<p><b><span style="font-size: 18pt;">Readme</b></span>
<br> &nbsp;<br>
This is a C language project that configures
the DAC in a simple software output.
The analog reference of 2.5V is used for the DAC.
In the first main, the DAC output occurs in the main program,
with digital input varying from 0 to 4095.
In the second main, the DAC output is updated within the TimerG0 ISR,
creating a sinusoidal wave.
<br>&nbsp;<br>
The following scope trace shows the DAC output on PA15. The frequency of
the sine wave output is <br><br>
&nbsp;&nbsp;&nbsp;<i>frequency</i> = <i>Interrupt Frequency</i> / <i>Table size</i>
= 200kHz/64 = 3.125kHz</p>
<p class="PictureWide"><span lang="en-US"><img src="DACout_voltage.png"
></span></p>
<p>
The spectrum analyzer shows a 1.058dB peak at 3.123 kHz (signal)
and a -37.16dB peak at 7.024kHz (noise).
We can calculate SNR as 1.058 minus -37.16dB = 38.2dB.
One might expect the SNR of a 12-bit DAC to be 20*log(2^12) = 72dB.
However, without an analog filter, the SNR is limited by the size
of the table, 20*log(64) = 36.1 dB. You can see individual steps in the above
analog trace.

The 'targetConfigs' folder contains target-configuration (.ccxml) files, automatically generated based
on the device and connection settings specified in your project on the Properties > General page.
Please note that in automatic target-configuration management, changes to the project's device and/or
connection settings will either modify an existing or generate a new target-configuration file. Thus,
if you manually edit these auto-generated files, you may need to re-apply your changes. Alternatively,
you may create your own target-configuration file for this project and manage it manually. You can
always switch back to automatic target-configuration management by checking the "Manage the project's
