FreqCalcSX1280_calcFreqToRegister()

void FreqCalcSX1280_calcFreqToRegister	(	uint32_t	freq,
		uint8_t *	msb,
		uint8_t *	mid,
		uint8_t *	lsb
	)

Translates a given frequency to the according register values of the TRX.

Note: This is not 100% exact. (see formula in TRX datasheet)

Parameters

freq	RF mid frequency in Hz
msb	pointer where to store the MSB register value
mid	pointer where to store the MID register value
lsb	pointer where to store the LSB register value

Translates given register values to a carrier frequency.

Note: This is not 100% exact. (see formula in TRX datasheet) *

Parameters

msb	the MSB register value
mid	the MID register value
lsb	the LSB register value

Return values

the	corresponding frequency in Hz
