The KS_TEA5767 library facilitates easy integration and control of the TEA5767 FM radio module via I2C communication. It includes functions for setting the frequency, retrieving RSSI values, detecting stereo mode, and checking PLL status, offering comprehensive capabilities for managing FM radio functionality in embedded systems.

Installation

1. Download the library as a ZIP file from the GitHub repository.
2. Open the Arduino IDE.
3. Go to Sketch > Include Library > Add .ZIP Library....
4. Select the downloaded ZIP file.

List of functions

Function Name	Input Parameter	Returned Parameter	Description (English)
getPLL	None	bool	Checks if the PLL is locked (true for locked, false for unlocked).
getRSSI	None	int	Returns the Received Signal Strength Indication (RSSI) value.
getRSSIdBm	int rssi	int	Converts the RSSI value to dBm scale and returns it.
getStereo	None	bool	Checks if the radio is in stereo mode (true for stereo, false for mono).
getHex	None	String	Returns the status bytes received from TEA5767 in hexadecimal format.
getBin	None	String	Returns the status bytes received from TEA5767 in binary format.
getDec	None	String	Returns the status bytes received from TEA5767 in decimal format.
getASCII	None	String	Converts the status bytes received from TEA5767 to ASCII characters. Non-printable characters are replaced with ".".
setFrequency	float frequencyMHz	None	Sets the frequency of the TEA5767 module to the specified value in MHz.
