Function Documentation

int16_t mpxx6115a_press	(	adcread_t	vout,
		adcread_t	vref
	)			[inline]

Covert read voltage from MPXX6115A Pressure Sensor in hPascal value.

The convertion formula may be consulted on costructor datasheet (see Freescale Semiconductor MP3H6115A, MPXAZ6115A).

Parameters:

	vout	output voltage read from pin sensor.
	vref	reference voltage that supplies the MPXX6115A sensor.

Returns:

interger value that represent measured pressure in hPascal.

Note:

: To compute the pressure we use the Vout/Vref ratio, so these two values can be expressed in any unit, even adc levels.
