Detailed Description

An Arduino sketch to operate a SI4703 chip based radio using the Radio library.

Author
Matthias Hertel, http://www.mathertel.de

This sketch implements a "as simple as possible" radio without any possibility to modify the settings after initializing the chip.
The radio chip is initialized and setup to a fixed band and frequency. These settings can be changed by modifying the FIX_BAND and FIX_STATION definitions.

Open the Serial console with 57600 baud to see the current radio information.

Wiring

The SI4703 board has to be connected by using the following connections:

Arduino UNO pin Radio chip signal
3.3V (red) VCC
GND (black) GND
A5 or SCL (yellow) SCLK
A4 or SDA (blue) SDIO
D2 (white) RST
