Function Documentation

checkI2C()

int SI470X::checkI2C

(

uint8_t *

addressArray

)

Check the I2C bus address.

For some reason, the BK1088 device does not work with the standard Wire.h library of Arduino.

The checkI2C function is only used to test the circuit.

In practice, no function from the Wire.h library is utilized in a real application with the BK1088 in this project.

Parameters

uint8_t

address Array - this array will be populated with the I2C bus addresses found (minimum three elements)

Returns

0 if no i2c device is found; -1 if error is found or n > 0, where n is the number of I2C bus address found

convertToChar()

void SI470X::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 othetr generic similar functions

You can use it to format frequency using decimal or tousand separator and also to convert smalm 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 tousand separator position
separator	symbol "." or ","
remove_leading_zeros	if true removes up to two leading zeros (default is true)
