Resources and Going Further

Here are some useful resources to look at for the MiniGen board:

• MiniGen product page - Product page on SparkFun.
• AD9837 product page at Analog Devices's website - Lots of good info here about the product, other related products, and direct digital synthesis in general.
• AD8045 product page - Information about the op-amp on the board.
• Analog Devices's FilterWizard - A nice online tool that will help you tweak the values in this circuit, if you decide you need a different filter design.
• GitHub repository - Contains board design files and the Arduino Library.

The MiniGen can be used for all kinds of signal synthesis, but one of the more intriguing possibilities it opens up is signal transmission by Frequency Shift Keying. By switching between the FREQ0 and FREQ1 registers, it's possible to encode data on the output.

If you make anything neat using FSK with the MiniGen, or any other projects, let us know!
