This is an Arduino library for the SI4844, BROADCAST ANALOG TUNING DIGITAL DISPLAY AM/FM/SW RADIO RECEIVER, IC from Silicon Labs. It is available on Arduino IDE. This library is intended to provide an easier interface to control the SI4844.

The Si4844 is an analog-tuned digital-display AM/FM/SW radio receiver. It has an analog-tune while frequency, band, and setero/mono information can be displayed on LCD. It works with a I2C protocol that allows a microcontroller send command and receive data. Also, with a 100K variable resistor, you can simulate a dial mechanical tuning wheel found in old or traditional receiver. In this way, you will be able to offer a look similar to the old radios.
