Modules
Here is a list of all modules:
 Audio setup
 Deal with Interrupt and I2C bus
 Device Setup and Start up
 FM Mono Stereo audio setup
 FM RDS/RBDS
 Host and slave MCU setup
 SI4735-D60 / SI4732-A10 NBFMNarrow Band FM (Frequency Modulation) implementation.

First of all, it is important to say that the NBFM patch content is not part of this library. It is important to note that the author of this library does not encourage anyone to use the NBFM patches content for commercial purposes. In other words, this library only supports NBFM patches, the patches themselves are not part of this library.
 Si4735-D60 Single Side Band (SSB) supportSingle Side Band (SSB) implementation.

First of all, it is important to say that the SSB patch content is not part of this library. The paches used here were made available by Mr. Vadim Afonkin on his Dropbox repository. It is important to note that the author of this library does not encourage anyone to use the SSB patches content for commercial purposes. In other words, this library only supports SSB patches, the patches themselves are not part of this library.
