Detailed Description

Radio implementation including LCD output.

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 DisplayMono ( uint8_t v )

Display the current mono switch.

void DisplayServiceName ( char * name )

Update the ServiceName text on the LCD display when in RDS mode.

void DisplaySoftMute ( uint8_t v )

Display the current soft mute switch.

void DisplayTime	(	uint8_t	hour,
		uint8_t	minute
	)

void DisplayVolume ( uint8_t v )

Display the current volume.

void doMenuClick ( )

void doSeekClick ( )

RotaryEncoder encoder	(	A9	,
		A8
	)

Setup a RoraryEncoder for pins A2 and A3:

ISR ( PCINT2_vect )

LiquidCrystal_PCF8574 lcd ( 0x27 )

get a LCD instance

The lcd object has to be defined by using a LCD library that supports the standard functions When using a I2C->LCD library ??? the I2C bus can be used to control then radio chip and the lcd.

void loop ( )

Constantly check for serial input commands and trigger command execution.

OneButton menuButton	(	A10	,
		true
	)

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

void runCommand	(	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.

OneButton seekButton	(	A11	,
		true
	)

void setup ( )

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

SI4703 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 rot_state

RADIO_STATE state

The state variable is used for parsing input characters.
