On a 20M DC receiver: My eBay Dataseet worked fine with your sketch. Thanks for your blog. An Evaluation Board is a board engineered to show the performance of the model, the part is included on the board. Product Lifecycle Production At least one model within this product family is in production and available for purchase.

A general description, including details of the simple API and physical hook-up, appears on my blog: Hi Ron, Thanks for the post. I mean, does the output, referenced to GND, vary from How tight is the output sine at low e. Interestingly, if I use the 3. If the latter is true, do you happen to know of a method to remove the bias? There are some very similar 1.


I borrowed your code and testited mine …. The package for this IC i. I just used your code to make a nice CW qrpp beacon: This is a very neat job you did.

I first purchased the Dark blue board with four jumpers and two rows if pins next to each other. I sent a Arduino shield kit for a and it never worked.

With a 12v DC input, the regulator does run slightly warm so I fitted it with a small heatsink.

I found more data online, and the seller could not provide support. I am using interrupts to get the timing, and for the 80ms between the pulses I am try to send 0hz datasheeg the AD or I do a master reset. Frequently Asked Questions 1. In other words, would it be worthwhile buying one or two more from different suppliers?

Testing an eBay AD9850 DDS module with Arduino Uno

Good luck with your project. Here is the modified code: The Year of the Waveform Generator. D9 is a PWM pin so the display’s backlight brightness can be adjusted if desired. Didn’t find what you were looking for? Here are couple of pictures: As I stated earlier my old TekA died. I have at fatasheet 1 says 3.


I am using this as an oscillator in other radios. Model Package Pins Temp. Do you know what function R13, the little trimpot, performs? For more information about lead-free parts, please consult our Pb Lead free information page.
