The QN8066 is a enjoyable little FM transmitter chip. It covers the complete FM broadcast band and has built-in DSP. You’d discover this form of half in automobile mobile phone adapters earlier than each automobile included Bluetooth or an AUX port. [Ricardo] has created an Arduino library to bring the QN8066 to the masses.
The chip is reasonably straightforward to make use of – management is dealt with with a standard I2C interface. All of the complicated components – Part Locked Loop (PLL), RF entrance finish, energy administration, and audio processing are all hidden inside. [Ricardo’s] library makes it even simpler to make use of. One of many superior options of the 8066 is the truth that it handles Radio Knowledge System (RDS). RDS is the subcarrier datastream that enables FM stations to inject data like music title and artist into the sign. The information is then displayed in your radio display.
You’ll find the supply to [Ricardo’s] library on GitHub. Utilizing it is so simple as selecting it up from the Arduino IDE.
In case you are searching for an RDS-enabled radio to check out your QN8066 design, you wouldn’t do too unhealthy with this Gameboy cartridge receiver.
