Arduino Arbitrary Waveform Generator

The data values should be in decimal whole numbers in the range 0 to 63.

Arduino arbitrary waveform generator. Learn how to make your own arbitrary waveform generator using an atmega328p a dds function generator ic an op amp a few passives and some hard work. Arduino due arbitrary waveform generator. It outputs four waveshapes. There are a few example wave files in the arbitrary waves folder just for fun to help you get started.

This is my arduino based waveform generator using a 8 bit resistor ladder dac. Arduino due arbitrary waveform generator project tutorial by bruceevans. These values when loaded to the arduino uno are converted to hex values between 0x00 and 0x1f and output as arbitrary waveforms. This waveform generator is powered by an arduino.

The frequency pulse width and overall amplitude gain of the waveforms is controlled by three potentiometers. It runs with a sampling rate of 65536 hz and can create any whole number frequency from 1 hz to 30ish khz in sine wave sawtooth triangle and different ratios of square wave. Dac output circuitry for an arbitrary waveform generator. Arbitrary waveform data should be created as a csv file containing one column of data with length 128.

Arbitrary waves can be drawn edited saved opened and uploaded to the due via usb or the due can run alone controlled by pots switches. Things used in this project. Microcontroller design for an arbitrary waveform generator. My generator produces an amplified signal and also a unamplified high quality signal.

For general usage you can pretty much use any dac chip. Arbitrary waves can be drawn edited saved opened and uploaded to the due via usb or the due can run alone controlled by pots switches. It may be to test an amplifier check out a circuit a component or an actuator. Beginner full instructions provided 18 926.

Dac schematic design for an arbitrary waveform generator. In this article we will learn how quickly and easily we can build our own function generator using arduino this function generator a k a waveform generator can produce square wave 5v 0v with frequency ranging from 1hz to 2mhz the frequency of the wave can be controlled by a knob and the duty cycle is hardcoded to 50 but it is easy to change that in the program as well. Sine triangle pulse and saw each waveshape ranges in frequency from 1hz 50khz. Building a very basic arbitrary waveform generator is actually quite simple using a digital to analog converter dac chip and a microcontroller mcu.

As well as the gui program the arduino waveform generator can also be controlled by arduino s serial monitor set to 115200 baud. Powerful waveform generators are available commercially but it is relative.
