Im newbie. I buy AD as like at the picture. Im try to connect AD to my UNO: ***. Using digital pins 8 through 11, proto shield installed. 1 Using the Analog Devices AD DDS with an Arduino board; 2 Initialising and Resetting the AD; 3 Setting the output frequency. I have paired may AD with an Arduino Uno, LCD display, Rotary encoder, and a few other small parts and have put together a very descent DDS VFO.

Did you or anyone else arduinl it out? It worked great for me. A coupling cap is required there must be some DC in the sine wave or something. The amount of shift is determined by a setting set in the top portion of the code easily found. Drag this AD folder to the following location: Your code worked the very first time I switched it on, and your well commented sketch helped me a great deal in my intro to the Uno.
AD9850 DDS VFO
The 3x multiplication is an analog multiplier in an old mobiliphone set. The Arduino provides the 5V on a pin. The nice part is that if you did replace it with the AD you would get a much wider tuning range over the PTO. Thank you very much. When I rotate the encoder, the first line turns almost invisible; I think this is because a refresh issue?
If you build something from my design please send me a picture or a video of your creation. Do you get output to the LCD? Great project, I was able to build it within an hour. Less confusing for me. Thanks for your reply, Rich. Myself and hundreds of others have used the schematic exactly as drawn. Thanks for the reply Rich. Will keep you posted and share the build when all the goodies arrive from China! I am wondering whether we can modify it such that it can be used as a swept frequency source for an antenna analyzer application.
Fantastic circuit worked straight away with the same components. You did not properly include the Rotary library.
All the code is even published there: May people report success with the sketch on Win7. I will use a relay in the transceivers PTT circuit to operate the A5 switching. Thanks Rich, I bricked the chip so waiting on a new one. Thanks a lot for your wonderful yet simple circuit and code.
Forgive me Jeff, I forgot to give u my email address: Hello Excuse me my English expression. The are really tiny for something so useful. Thanks Tony for the comment. Do I need to add both to the IDE? Do you think this could be done, and do you think the existing display on the ffont of the could be retained, like to hear from youBrian. Thanks for the project as it work like a champ.
This page was last modified on 22 Aprilat Can you give me a helping hand to achieve this please? One last thing that is not Mega specific was a labeling errata in the wiring diagram.
Many people have taken my DDS project and expanded on it by learning how to program the arduino. If both ino files are in the same folder it will not compile. Or am I looking at the wrong file?
Arduino – AD Waveform Generator
Your problem is here: I did the same, Luke. Save the sketch under a new folder with a new name. It was fairly easy to figure out what to change ar9850 get it to work. Would you kindly advisee please.
Beside LCD it also is including an increment encoder and some joystick control: Please could u send me your working sketch…! The project is to become my new bench RF sig generator so will be looking at the N3ZI buffer amp and a stepped attenuator. For me, the easiest way to manage the AD is with an Arduino Uno. No such file or directory. I Have not a spctrum analycer, but I think the signal from the AD is very dirty.
Over the 10 Hz to 2. I have a question about the Arduino Uno. If you goof, I have a button that resets the HET frequencies and stored frequency memories back to a predetermined table.
