This is a Arduino sketch that uses a state machine to scan through all radio stations the radio chip can detect and outputs them on the Serial interface.
Open the Serial console with 57600 baud to see current radio information and change various settings.

Wiring

The necessary wiring of the various chips are described in the Testxxx example sketches. No additional components are required because all is done through the serial interface.

More documentation and source code is available at http://www.mathertel.de/Arduino

Enumeration Type Documentation

enum SCAN_STATE

State definition for this radio implementation.

The radio object has to be defined by using the class corresponding to the used chip. by uncommenting the right radio object definition.

Enumerator
STATE_START	waiting for a new command character.
STATE_NEWFREQ
STATE_WAITFIXED
STATE_WAITRDS
STATE_PRINT
STATE_END	executing the command.

Function Documentation

void loop ( )

Constantly check for serial input commands and trigger command execution.

void RDS_process	(	uint16_t	block1,
		uint16_t	block2,
		uint16_t	block3,
		uint16_t	block4
	)

void runSerialCommand	(	char	cmd,
		int16_t	value
	)

Execute a command identified by a character and an optional number. See the "?" command for available commands.

Parameters

cmd	The command character.
value	An optional parameter for the command.

void setup ( )

Setup a FM only radio configuration with I/O for commands and debugging on the Serial port.

Variable Documentation

SCAN_STATE state

The state variable is used for parsing input characters.
