Function Documentation

setRX()

void QN8066::setRX

(

uint16_t

frequency

)

SYSTEM1 SETUP.

sets the devive to RX

Parameters

frequency

- frequency that the receiver will start

Todo:

Need to be optimized to improve space size

setRxFrequency()

void QN8066::setRxFrequency

(

uint16_t

frequency

)

sets the receiver frequency

setRxFrequencyRange()

void QN8066::setRxFrequencyRange	(	uint16_t	min = 640,
		uint16_t	max = 1080
	)

Sets the frequency range of the receiver.

default values is 64.0 Mhz (640) to 108.0 MHz (1080)

Parameters

min
max

setRxFrequencyUp()

void QN8066::setRxFrequencyUp

(

)

Increments the current receiver frequency.

Todo:

under construction...

setRxFrequencyDown()

void QN8066::setRxFrequencyDown

(

)

Decrements the current receiver frequency.

Todo:

under construction...

setRxFrequencyStep()

void QN8066::setRxFrequencyStep

(

uint8_t

value

)

Sets the current Step frequency.

0 = 50KHz; 1 = 100KHz; 2 = 200KHz; 3 = Reserved

Parameters

value

rdsEnableRX()

void QN8066::rdsEnableRX

(

bool

value

)

Enables RDS for RX.

setAudioMuteRX()

void QN8066::setAudioMuteRX

(

bool

value

)

Mute or unmute the audio in receiver mode.

Parameters

value

- if true mutes the audio; if false, mute disabled

getRxSNR()

uint8_t QN8066::getRxSNR

(

)

Gets the current SNR (Estimated RF input)

Returns

current SNR in dB

getRxRSSI()

uint8_t QN8066::getRxRSSI

(

)

Gets the current RSSI.

In-band signal RSSI (Received signal strength indicator) dBuV value. dBuV=RSSI-49

Returns

current RSSI in dB

isValidRxChannel()

bool QN8066::isValidRxChannel

(

)

Gets a valid or no valid rx channel.

RXCCA status flag. To indicate whether a valid channel is found during RX CCA.

If a valid channel is found, channel index will stay there, and RXCCA_FAIL=0;

otherwise, it will stay at the end of scan range and RXCCA_FAIL=1.

Returns

true valid channel

false not found a valid channel

isRxReceiving()

bool QN8066::isRxReceiving

(

)

Receiver status.

Returns

true - Is receiving

isRxAgcStable()

bool QN8066::isRxAgcStable

(

)

RX AGC Status.

RX AGC Settling status

Returns

true - Settled / Stabled

isRxStereo()

bool QN8066::isRxStereo

(

)

Stereo receiving status.

Returns

true - Stereo

scanRxStation()

void QN8066::scanRxStation	(	uint16_t	startFrequency,
		uint16_t	stopFrequyency,
		uint8_t	frequencyStep
	)

Scans a station.

Searches for a station within a specified frequency range.

Parameters

startFrequency	- initial frequency to start the search.
stopFrequyency	- final frequency to stop the search.
frequencyStep	- 0 = 50KHz; 1 = 100KHz; 2 = 200KHz
