A signal generator project using the
and a module with the IC AD9833 DDS.
The module can generate from 0 to 12.5 MHZ square, triangle and sine wave.
There are many boards with the AD9833 chip. I used the one that has an on board amplifier.
Step 1: Set Up
1. connect the AD9833 module
with the U1.
2. Upload the sketch found in the library of the InvIoT. Open your arduino IDE, file/examples/InvIoT_U1/applications/signalGenerator
3. Upload sketch
Step 2: The Code.
I include a file with the code.
The code can be also found in the library, and in order to run the code you need to download the library.
