SparkFun_MiniGen_Library_Test.ino
3+
Library test file for the MiniGen library.

7+
8+
This is a simple test/example file for the MiniGen board and library.
9+
10+
The MiniGen is a Pro Mini shield-type board (although it can be used as a
11+
standalone product as well) that generates sine, square and triangle waves up
12+
to a frequency of approximately 3MHz; above 3MHz, you'll start to see rolloff
13+
as the anti-aliasing filter on the output begins to affect the signal. Expect
14+
a peak-to-peak amplitude of about 1V and a DC offset of Vcc/2.
15+
16+
Resources:
17+
Uses the MiniGen library and the built-in SPI library.
18+
19+
Development environment specifics:
20+
Code developed in Arduino 1.0.5, on an Arduino Pro Mini 5V.
21+
22+
**Updated to Arduino 1.6.4 5/2015**
