Introduction: Signal Generator Using Inviot U1, an Arduino Compatible Board

By

A signal generator project using the

.

InvIoT U1board

.

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.

AD9833 U1

VCC 5V

GND GR

FSY D10

CLK D13

DAT D11

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.
