• VCC: Power supply (3.3V or 5V depending on the module specifications)
• SDA: I2C data line
• SCL: I2C clock line
• RCK: (Not always used) Clock input for the microcontroller
• RST: Reset pin (optional)

Connecting the Module to Arduino

Here’s how you can connect the TEA5767 module to an Arduino:

1. VCC to 3.3V or 5V: Connect the VCC pin of the module to the 3.3V or 5V pin on the Arduino (check the module’s specifications).
2. GND to GND: Connect the GND pin of the module to the GND pin on the Arduino.
3. SDA to A4: Connect the SDA pin of the module to the A4 pin on the Arduino (for I2C communication).
4. SCL to A5: Connect the SCL pin of the module to the A5 pin on the Arduino (for I2C communication).
5. RST (optional): If you want to use the reset functionality, connect the RST pin to a digital pin on the Arduino.

Arduino Code Example

To get started with the TEA5767 module, you can use the following Arduino code. This code initializes the module and scans for FM stations.

#include <Wire.h>

#include <TEA5767Radio.h>
TEA5767Radio radio = TEA5767Radio();
void setup() {
Serial.begin(9600);
Wire.begin();
radio.init();
Serial.println("TEA5767 FM Radio Module Test");
}
void loop() {
float frequency = 87.5;
radio.setFrequency(frequency);
delay(2000);
Serial.print("Tuned to frequency: ");
Serial.println(frequency);
delay(5000);
}

Libraries

To use the TEA5767 module, you need to install the TEA5767Radio library. You can install it via the Arduino Library Manager:

1. Open the Arduino IDE.
2. Go to Sketch > Include Library > Manage Libraries.
3. Search for “TEA5767Radio” and install it.

Additional Tips

• Antenna Placement: Ensure the antenna is properly connected and placed in a location with minimal interference for better reception.
• Power Supply: Double-check the power supply requirements of your specific TEA5767 module. Some modules require 3.3V while others might work with 5V.
• Filtering: If you experience noise or poor signal quality, consider adding additional filtering capacitors between VCC and GND.
