◆ setI2CBusAddrs()

void RDA5807::setI2CBusAddrs	(	int	directAccess,
		int	fullAccess
	)

inline

Sets alternatives I2C bus address.

You do not need use this function on RDA5807M

Parameters

directAccess
fullAccess

References RDA5807::deviceAddressDirectAccess, and RDA5807::deviceAddressFullAccess.

◆ getStatusRegisters()

void RDA5807::getStatusRegisters ( )

Gets all current device status and RDS information registers (From 0x0A to 0x0F)

See also: RDA5807M - SINGLE-CHIP BROADCAST FMRADIO TUNER; pages 5, 9, 12 and 13.; rda_reg0a, rda_reg0b, rda_reg0c, rda_reg0d, rda_reg0e, rda_reg0f; shadowStatusRegisters;

◆ getStatus()

void * RDA5807::getStatus ( uint8_t reg )

Gets the register content of a given status register (from 0x0A to 0x0F)

Useful when you need just a specific status register content.

This methos update the first element of the shadowStatusRegisters linked to the register

Returns: rdax_reg0a the reference to current value of the 0x0A register.

◆ setAllRegisters()

void RDA5807::setAllRegisters ( )

Sets values to the device registers from 0x02 to 0x07.

An internal address counter automatically increments to allow continuous data byte writes, starting with the upper byte of register 02h, followed by the lower byte of register 02h, and onward until the lower byte of the last register is reached.

The registers from 0x2 to 0x07 are used to setup the device. This method writes the array shadowStatusRegisters. See Device registers map in RDA5807.h file.

To implement this, a register maping was created to deal with each register structure. For each type of register, there is a reference to the array element.

See also: shadowStatusRegisters;

◆ setRegister()

void RDA5807::setRegister	(	uint8_t	reg,
		uint16_t	value
	)

Sets a given value to a specific device register.

See also: RDA5807M - SINGLE-CHIP BROADCAST FMRADIO TUNER; pages 5, 9, 10 and 11.; rda_reg02, rda_reg03, rda_reg04, rda_reg05, rda_reg06, rda_reg07

Parameters

reg	register number (valid values is between 0x02 and 0x07)
value	the unsigned 16 bits word value (see rda_rec0x data types)

◆ waitAndFinishTune()

void RDA5807::waitAndFinishTune ( )

Waits for Seek or Tune finish.

Referenced by RDA5807::setChannel().

◆ softReset()

void RDA5807::softReset ( )

Resets the device.

The RDA5807M is RESET itself When VIO is Power up.

Also, it support soft reset by triggering the 0x02 register (rda_reg02) bit 1 from 0 to 1.

◆ powerUp()

void RDA5807::powerUp ( )

Powers the receiver on.

Referenced by RDA5807::setup().
