xv4y 46 Posted March 20, 2013 Share Posted March 20, 2013 Hi, This will ring a bell to radioamateurs (HAM radio) but other may just ignore... I have posted to my blog a code for a simple VFO (Variable Frequency Oscillator) or better said an RF frequency generator using an AD9850 DDS chip. This code is simple and has no special trick but might give you inspiration. http://xv4y.radioclub.asia/2013/03/19/code-source-vfo-avec-dds-ad9850ad9851-et-launchpad-msp430/ The pins are "wired" for my WSPR agile beacon generator kit, but everything can be changed to your taste or needs. The text of the blog article is in french but has no additional information than the one in the source code (commented in english). The needed libraries are on my download page : http://xv4y.radioclub.asia/boutique/docs/ Regards, Yannick. SirPatrick, RobG, energia and 1 other 4 Quote Link to post Share on other sites

xv4y 46 Posted March 20, 2013 Author Share Posted March 20, 2013 Yes very useful. I think you have made some updated but I stick with an old version since it works well for me. I will check the updates later but I still have some stuff I want to put in my own code before. Yan. Quote Link to post Share on other sites
