begin()

void QN8066::begin

(

)

Device initial configuration.

The functions described in this group are used to configure the QN8066.

Starts the QN8066 instance.

It is a minimalist code to initiate the QN8066 device. Use the function setup if you want more option during the start process.

Example

#include <QN8066.h>
QN8066 tx;
void setup() {
  // Call setup setting Divider = 1000, Stereo, RDS on and PreEmphasis (tc) 75us
  tx.begin(); 
  tx.setTX(1069); // Set the transmitter to 106.9 MHz 
}
 
void loop() {
}

setTxMode()

void QN8066::setTxMode ( uint8_t  value )

inline

Set transmission request.

This function enable or disable transmission

Parameters

value

- 0 = disable; 1 = enable

stopTransmitting()

void QN8066::stopTransmitting

(

)

Stops transmitting.

startTransmitting()

void QN8066::startTransmitting

(

)

Starts transmitting.

QN8066 initial configuration.

This function can be called without arguments (parameters). In this case, the default value will be assumed. See the following list of parameters.

Parameters

xtalDiv	- Divider based on frequency select of reference clock source. Default 1000 (see Datasheet pag. 18 and 23).
mono	- If false, the TX will start stereo mode. Default false.
rds	- if true, TX will start with RDS on. Default false.
PreEmphasis	- Valid values: 0 or 1 (0=50us; 1=75us). Default 0.
xtalInj	- type of the reference clock source (0 = Inject sine-wave clock; 1 = Inject digital clock).
imageRejection	- Image Rejection (0=LO<RF, image is in lower side; 1=LO>RF, image is in upper side).
txSoftClipThreshold	- TX soft clip threshold. Default 0. See Datasheet page 34.
oneMinutOff	- Selection of 1 minute time for PA off when no audio (3 = Infinity (never); 2=59s; 1=58s; 0=57s).
gainTxPLT	- Gain of TX pilot to adjust pilot frequency deviation. See Datasheet page 34.
txFreqDev	- Specify total TX frequency deviation. TX frequency deviation = 0.69KHz*TX_FEDV. Default 125.
rdsLineIn	- Audio Line-in enable control. Default 0
rdsFreqDev	- RDS frequency deviation. RDS frequency deviation = 0.35KHz*RDSFDEV in normal mode. Default 60
inImpedance	- TX mode input impedance for both L/R channels (Default 1 => 20K )
txAgcDig	- TX digital gain (Default 0)
txAgcBuffer	- TX input buffer gain (Default 1)
txSoftClip	- TX soft clipping enable (Default 0 - Disable)

Example

#include <QN8066.h>
QN8066 tx;
void setup() {
  // Call setup setting Divider = 1000, Stereo, RDS on and PreEmphasis (tc) 75us
  tx.setup(1000, false, true, 1); 
  tx.setTX(1069); // Set the transmitter to 106.9 MHz 
}
 
void loop() {
}

setXtal()

void QN8066::setXtal	(	uint16_t	divider,
		uint8_t	xtalInj,
		uint8_t	imageRejection
	)

QN8066 initial configuration of the of reference clock source.

Reference clock source based on the active crystal or signal generator you are using.

The table below shows some tested sources (active crystal or signal generator) and divider values

Source (kHz)	Divider
32.768	1

Parameters

xtalDiv	- Divider based on frequency select of reference clock source. Default 1000 (see Datasheet pag. 18 and 23).
xtalInj	- type of the reference clock source (0 = Inject sine-wave clock; 1 = Inject digital clock).
imageRejection	- Image Rejection (0=LO<RF, image is in lower side; 1=LO>RF, image is in upper side).

Example

#include <QN8066.h>
QN8066 tx;
void setup() {
  tx.begin();
  tx.setXtal(1,1,1);
