Function Documentation

long MSPPSreadAbsPressure

(

tSensors

link )

Read the absolute pressure from the sensor and return it in the unit the sensor has been configured for.

Parameters:

link	the sensor port number

Returns:

the absolute pressure.

Examples:

mindsensors-pressure-test1.c.

Definition at line 105 of file mindsensors-pressure.h.

long MSPPSreadGaugePressure

(

tSensors

link )

Read the gauge pressure from the sensor and return it in the unit the sensor has been configured for. This is the absolute pressure minus the reference pressure.

Parameters:

link	the sensor port number

Returns:

the gauge pressure.

Examples:

mindsensors-pressure-test1.c.

Definition at line 118 of file mindsensors-pressure.h.

long MSPPSreadPressure	(	tSensors	link,
		ubyte	reg
	)

Read the pressure from the sensor and return it in the unit the sensor has been configured for.
It is better to use MSPPSreadAbsPressure(), MSPPSreadGaugePressure() or MSPPSreadRefPressure() instead

Parameters:

link	the sensor port number
reg	Specific pressure register to read.

Returns:

the absolute pressure.

Definition at line 84 of file mindsensors-pressure.h.

long MSPPSreadRefPressure

(

tSensors

link )

Read the reference pressure from the sensor and return it in the unit specified.

Parameters:

link	the sensor port number

Returns:

the reference pressure.

Definition at line 130 of file mindsensors-pressure.h.

bool MSPPSsendCmd	(	tSensors	link,
		ubyte	command
	)

Send a command to the sensor

Parameters:

link	the sensor port number
command	the command to be sent

Returns:

true if no error occured, false if it did

Definition at line 173 of file mindsensors-pressure.h.

bool MSPPSsetRefPressure	(	tSensors	link,
		int	refpressure
	)

Set the reference pressure to the value specified.

Parameters:

link	the sensor port number
refpressure	the value the ref pressure register should be set to.

Returns:

true if no error occured, false if it did

Definition at line 142 of file mindsensors-pressure.h.

bool MSPPSsetRefPressure

(

tSensors

link )

Set the reference pressure to the current absolute pressure value.

Parameters:

link	the sensor port number

Returns:

true if no error occured, false if it did

Examples:

mindsensors-pressure-test1.c.

Definition at line 161 of file mindsensors-pressure.h.

bool MSPPSsetUnit	(	tSensors	link,
		ubyte	unit
	)

Set the unit of measurement to the one specified.

Parameters:

link	the sensor port number
unit	the unit of measurement to be used.

Returns:

true if no error occured, false if it did

Examples:

mindsensors-pressure-test1.c.

Definition at line 191 of file mindsensors-pressure.h.
