Arduino sketch for Si4703 FM Tuner Board with RDS Spy support

Arduino sketch helps to use Si4703 FM RDS Tuner Breakout Board with RDS Spy software (http://rdsspy.com). Made by Dmitrii [email protected]. 2016-07-03. Version 1.0

Usage:

1. Connect Si4703 FM RDS Tuner Breakout Board to Arduino

• 3.3V Arduino -> Si4704 VCC
• GND Arduino -> Si4704 GND
• A4 Arduino -> Si4704 SDIO
• A5 Arduino -> Si4704 SCLK
• D2 Arduino -> Si4704 RST

2. Upload "Si4703_RDS_Spy.ino" sketch to Arduino

3. Launch RDS Spy (http://rdsspy.com), select ASCII G Protocol data source and proper COM port in settings

4. Enjoy :)

Finally it looks like this:

Frequency can be changed via RDS Spy. Commands via serial port are also available (see the source code for details).
