Detailed Description

Function Documentation

setI2CLowSpeedMode()

void QN8066::setI2CLowSpeedMode ( void  )

inline

Sets I2C bus to 10kHz.

The functions below modify the clock frequency for I2C communication. 100kHz is usually the baseline. Use one of these funcition if you have a problem on the default configuration.

setI2CStandardMode()

void QN8066::setI2CStandardMode ( void  )

inline

Sets I2C bus to 100kHz.

setI2CFastMode()

void QN8066::setI2CFastMode ( void  )

inline

Sets I2C bus to 400kHz.

setI2CFastModeCustom()

void QN8066::setI2CFastModeCustom ( long  value = 500000 )

inline

Sets the I2C bus to a given value. ATTENTION: use this function with caution.

Parameters

value

in Hz. For example: The values 500000 sets the bus to 500kHz.

convertToChar()

void QN8066::convertToChar	(	uint16_t	value,
		char *	strValue,
		uint8_t	len,
		uint8_t	dot,
		uint8_t	separator = '.',
		bool	remove_leading_zeros = true
	)

Converts a number to a char array.

It is useful to mitigate memory space used by functions like sprintf or other generic similar functions

You can use it to format frequency using decimal or thousand separator and also to convert small numbers.

Parameters

value	value to be converted
strValue	char array that will be receive the converted value
len	final string size (in bytes)
dot	the decimal or thousand separator position
separator	symbol "." or ","
remove_leading_zeros	if true removes up to two leading zeros (default is true) #include <QN8066.h> QN8066 tx; char strFrequency[7]; uint16_t txFrequency = 1069; void setup() { char strFrequency[7]; tx.setup(); tx.setTX(1069); // Set the transmitter to 106.9 MHz tx.convertToChar(txFrequency, strFrequency, 5, 3, ','); // Convert 1069 to a array of char "106.9" } void loop() { }

formatCurrentFrequency()

char * QN8066::formatCurrentFrequency

(

char

decimalSeparator = ','

)

Convert the current frequency to a formated string (char *) frequency.

The current frequency is the latest setted frequency by setFrequency, seek, setFrequencyUp and setFrequencyDown.

Parameters

char	decimalSeparator - the symbol that separates the decimal part (Exe: . or ,)

Returns

point char string strFrequency (member variable)
