This folder has a set of examples that might help you in your project with Si4844 and Arduino.

This project is about a library to control the SI4844 device and the focus of this project is the library and its functionalities. Please, don't ask me to assist you in your: displays (LCD, OLED, TFT etc), encoders, buttons or something else out the library scope. Thanks.

The SI4844_MINIMAL.ino is a sketch with just 35 lines. It is enough to make a simple radio based on SI4844.

The SI4844_POC.ino is a proof of concept for SI4844 controlled by Arduino and the SI4844 Library. This Arduino Sketch only works on your IDE (Arduino IDE). However, you can replace the Serial Monitor functions that deal the SI4844 and arduino with functions that will manipulate the LCD, encoder and push buttons appropriated for your project.

The sketch SI4844_CUSTOM_BAND.ino shows how to extend a SW band frequency ranges. You can define band from from 2.3–5.6 MHz and 22–28.5 MHz.

The sketch SI4844_OLED.ino shows an example of using an I2C OLED display. This sketch uses the SSD1306Ascii Arduino Library by Bill Greiman. You must install SSD1306Ascii via Manage Libraries on your Arduino IDE.

The schematics below show how to add the OLED and buttons.

The sketch SI4844_BASS_TREBLE.ino show how to use sound control (treble, bass, mute etc).
