Detailed Description

Radio implementation using the Serial communication.

This is a full function radio implementation that uses a LCD display to show the current station information.
It can be used with various chips after adjusting the radio object definition.
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. The boards have to be connected by using the following connections:

Arduino port	SI4703 signal	RDA5807M signal
GND (black)	GND	GND
3.3V (red)	VCC	VCC
5V (red)	-	-
A5 (yellow)	SCLK	SCLK
A4 (blue)	SDIO	SDIO
D2	RST	-

Function Documentation

void DisplayFrequency ( RADIO_FREQ f )

Update the Frequency on the LCD display.

void DisplayServiceName ( char * name )

Update the ServiceName text on the LCD display.

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

RDA5807M radio

Create an instance of a RDA5807 chip radio.

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

RDSParser rds

get a RDS parser

RADIO_STATE state

The state variable is used for parsing input characters.
