NuGet package

The TEA5767 FM module is based on the TEA5767GH which is a single-chip, electronically tuned, FM stereo radio for low-voltage applications with fully integrated Intermediate Frequency (IF) selectivity and demodulation.

The TEA5767 is controlled via I2C. It comes with two 1/4" jacks, one for connection to a headphone/speaker and one to connect an antenna (often sold with the module).

Code Example

Tea5767 radio;

public override Task Initialize()
{
    Resolver.Log.Info("Initializing...");

    radio = new Tea5767(Device.CreateI2cBus());

    return Task.CompletedTask;
}

public async override Task Run()
{
    //scan through available stations
    for (int i = 0; i < 8; i++)
    {
        await Task.Delay(1000);

        radio.SearchNextSilent();

        Resolver.Log.Info($"Current frequency: {radio.GetFrequency()}");
    }

    //set a known station
    radio.SelectFrequency(new Frequency(94.5, Frequency.UnitType.Megahertz));
}
