Topic: I2C FM with Parallax 27984 (Read 1 time) previous topic - next topic


Here is a simple sketch using I2C and serial terminal to exercise the Parallax FM module (part 27984)


No external pullups need.

The Parallax documentation is incomplete. I had to examine the spin/stamp codes to figure out how to do seeks.  Parallax info:


With a few minor changes, sketch works on Maple.


thanks for your code, it's really usefull, I was having an hardtime trying to figure out how to work with this FM receiver. I'm having a problem in the audio out, I son't have any audio and I got the fail message as 1 1 1 like this:

config d001 0840 0400 86d7
fm channel 90.3  volume 7  ss 127  sst 6
status ffff ffff
seek channel 112.5  ss 127 stereo 1 complete 1 fail 1 1 1

Do you have any idea what the problem could be? I'm using a jack as the antenna.

Thank you so much

It works great with Arduino uno. I just need to know how to configure it to use all the controls via digital input. Please tell me how I could do this. I understand I use a command line for digital i/o. But how will I set up all the other functions such as bass, mute, mono etc.
