Hi Dave,
Thanks for the additional information about programming the ATtiny85 (your post of 14 March). That is very helpful. I have bought a couple of DDS boards and a few ATtiny85 boards. One of each appears to be identical to the boards shown in your photos, so that will give me a great place to start. I will try programming both ways.
Initially, I just want to synthesise a crystal, for which your approach using the ATtiny85 seems perfect. I note that there was also a very helpful article on getting started with this board in Silicon Chip, in March 2017.
Meanwhile, I am also interested in controlling the AD933 using a Micromite computer. First I found an article by Dan Amos on the Micromite Backshed forum ( thebackshed.com/forum ), and then I noticed that it had been described in Silicon Chip Circuit Notes in June 2016. This article described using a Micomite "Backpack", which is a 4.3" colour touchscreen, to turn the AD9833 into a signal generator. Then in Silicon Chip this month (April 2017), there is a full article on doing the same thing in a different way, and an article about the AD9833, including control using both Arduine and Micromite, in the series entitled "El Cheapo Modules", by Jim Rowe.
It was your original post that got me started on all this.
Thank you,
Lew.
