I recently purchased a NS73M FM radio transmitter module from SparkFun. I'm planning to put it into a project enclosure along with a Picaxe 20X2, a serial LCD and a couple buttons, all to create a small, portable FM radio transmitter. However, I still not sure that a Picaxe would actually be able to control the transmitter. I found an Arduino program for this module but it raised a couple questions about what the Picaxe can handle. First off, the program (http://www.km5z.us/files/arduino-fm/ARRduino_FM_v1/ARRduino_FM.pde with the project detailed at http://www.mikeyancey.com/FM-Stereo-Broadcaster.php) uses numbers that are bigger than a word can handle. I think this could be solved with a large enough lookup table, which the 20X2 could probably handle. Also, my understanding, or abilities, to read C are not very good, so I may be missing some other commands that could present problems.
Has anyone else here ever experimented with this FM transmitter module? If you have I'd love to know if it's at least possible to get it working. Or, just a hint or two to push me down the right path. One quick note. As most would already know, transmitters like these are illegal in some countries if you use much more than a short piece of wire as an antenna. Fortunately, I live in a desert, surrounded by mountains on all sides, and not in the US. So, I don't have to worry too much about disrupting either of the two radio stations that I can receive!
