Tutorial: How to Use the AD9833 DDS Signal Generator

The AD9833 module is a digital signal generator DDS (Direct Digital Synthesis) that allows for the creation of highly precise sine and square waves. Ideal for radio communication projects, testing, and measurement.

What you need

• Arduino Uno or similar
• USB cable
• Arduino IDE software

Steps

1. Connect the AD9833 module to the Arduino using a USB cable.
2. Install the DDS library for the AD9833 from the GitHub repository.
3. Include the build instructions for the library in the project configuration.
4. Configure the Arduino pins that will be used as output for the AD9833 module.
5. Set the desired frequency of the generated wave in the Arduino code.
6. Compile and upload the sketch to Arduino.
7. Verify the signal output with an oscilloscope or multimeter.
8. Adjust the parameters as needed to obtain the desired signal.

Example code

/* Includi la libreria DDS */
#include <DDS.h>

// Configura l'oggetto DDS
DDS dds;

void setup() {
  // Imposta la frequenza e inizializza il modulo
  dds.setFrequency(1000); // Hz
}

void loop() {}
