Arduino Library for SINGLE-CHIP BROADCAST FM RADIO TUNER RDA5807
RDA5807 Arduino Library
It is a cross-platform Arduini Library for RDA5807. You can use it with oficial Arduino boards, ATtiny, STM32 , ESP32 and more. It works with I2C protocol and can provide you an easier interface to control the RDA5807 device. This library was built based on “RDA5807M — SINGLE-CHIP BROADCAST FM RADIO TUNER — Rev.1.1–Aug.2015”
This library can be freely distributed using the MIT Free Software model.
The RDA5807 is a FM DSP integrated circuit receiver (50 to 115MHz) with low noise amplifier support. This device requires very few external components if compared with other similar devices. It also supports RDS/RBDS functionalities, direct auto gain control (AGC) and real time adaptive noise cancellation function. The PU2CLR RDA5807 Arduino Library was developed to take the most functionalities of this device. Plese, check the API Documentation for more details.
The photo below shows a Breakout that uses the RDA5807. You can find it on eBay, AliExpress and Amazon.

. This library was built based on “Si47XX PROGRAMMING GUIDE; AN332” and it has support to FM, AM and SSB modes (LW, MW and SW). It also can be used on all members of the SI47XX family respecting, of course, the features available for each IC version; . 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 for controlling the SI4844. . The AKC695X is a family of IC DSP receiver from AKC technology. The AKC6955 and AKC6959sx support AM and FM modes. On AM mode the AKC6955 and AKC6959sx work on LW, MW and SW. On FM mode they work from 64MHz to 222MHz. . The KT0915 is a full band AM (LW, MW and SW) and FM DSP receiver that can provide you a easy way to build a high quality radio with low cost. . The BK1086 and BK1088 are DSP receivers from BAKEN. The BK1088 is a BROADCAST FM and AM (LW, MW and ) RECEIVER and BK1086 is a subset of the BK1088 (it does not have LW and SW acording to the Datasheet). . The RDA5807 is a FM DSP integrated circuit receiver (50 to 115MHz) with low noise amplifier support. This device requires very few external components if compared with other similar devices. It also supports RDS/RBDS functionalities, direct auto gain control (AGC) and real time adaptive noise cancellation function. . It is a Silicon Labs device family that integrates the complete functionalities for FM receivers, including RDS (Si4703). . It is an Arduino Library to control the MCP23008/MCP23S08 8-Bit I/O Expander. The MCP23008 device provides 8-bit, general purpose, parallel I/O expansion. It can be controlled via I2C bus applications. It is a great and inexpensive device that allow you to add more devices to be controlled by your Arduino board via I2C protocol. . It is an Arduino Library to control the PCF8574 8-Bit I/O Expander. The PCF8574 device provides 8-bit, general purpose, parallel I/O expansion. It can be controlled via I²C bus applications. It is a great and inexpensive device that allow you to add more peripherals to be controlled by your Arduino board via I²C protocol.

The easiest method to install this library is via your Arduino IDE. All you have to do is:
- Select Tools menu;
- Select Manage Libraries option;
- In the text box (top windows), type PU2CLR or RDA5807;
- Select the PU2CLR RDA5807.
The images below show how you can install this library via your Arduino IDE from Manage Libraries tool.
Installing via the repository
With this approach, you will have the most current version of the library. However, it may not be the most stable version. This is because the current version is always in development. Prefer releases. Do you need some old version (release) of this library? If yes, check here.
First, you have to download this library in zip format.
After, unzip the RDA5807-master.zip file in your Arduino Library folder.
