go-si4703

A go library to interact with the Si4703 FM Tuner (with RDS support).

NOTE: This has only been tested on a Raspberry Pi.

Connections

• SDIO/SCLK/3.3V/GND as you would any other I²C/2-wire device.
• RST to GPIO 23 on the rpi (needed to put device into 2-wire mode)

Examples

There is one example app allowing you to interact with the tuner.
