Interfacing TEA5767 FM Radio Module with Arduino

Step 1: Circuit

Connect the module to Arduino according to the following image.

Note

To receive signal, you should connect a headphone or antenna to the antenna jack.

Step 2: Installing Library

Install following library on your Arduino board.

https://github.com/big12boy/TEA5767.git

Step 3: Code

Upload the following code to Arduino.

#include <TEA5767.h>
TEA5767 radio = TEA5767();

//User changeable
short minlvl = 14; //Required Signal Level (0-5=unuseable, 6-9=poor, 10-12=good, 13-14=really good, 15=excellent)
long baud = 250000; //Baudrate of the Serial Interface
//---------------

void setup() {
  Serial.begin(baud); //Initialize Serial Connection
  
  radio.init(minlvl); //Initialize needed Features and search for Stations

  //Print the result
  Serial.print("Found ");
  Serial.print(radio.getStations()); //Get Number of Stations from Library
  Serial.println(" Station(s):");
  Serial.println();

  //Print all available Stations
  listStations();
  
  Serial.println("Send something to change to the next Station!");
}

void loop() {
  //Wait for User Input
  if(Serial.available()){
    radio.nextStation(); //Switch to next Station

    delay(50);    //Wait for the Signal to stabilize
    printStation(); //Print Station Details

    while(Serial.available())Serial.read(); //Clear the Serial Buffer
  }
}

void listStations(){
  short stations = radio.getStations(); //Get available Stations
  for(short i = 0; i < stations; i++){ //Go through all Stations
    delay(50);  //Wait for the Signal to stabilize
    printStation(); //Print Details
    radio.nextStation(); //Jump to the next Station
  }
  Serial.println("----------------------"); //Finish of the List
}

void printStation(){
  Serial.print("Frequency:   ");
  Serial.println(radio.getFrequency()); //Print current Frequency
  Serial.print("Signallevel: ");
  Serial.println(radio.getSignalLevel()); //Print current Signal Level (0-15)
  Serial.println();
}

After running the code, you will see the following image in the serial output.

I tried many different codes for TEA5767. This was the most “friendly” code output I got.

I am not a programmer, I thought that it would be easier, honestly.
