Function Documentation

int bmp085_get_cal_param ( void )

read out parameters cal_param from BMP085 memory

Returns:: result of communication routines

Definition at line 178 of file bmp085_bst.c.

long bmp085_get_pressure ( unsigned long up )

calculate pressure from up up was read from the device via I2C and fed into the right calc path for either SMD500 or BMP085 In case of SMD500 value averaging is done in this function, in case of BMP085 averaging is done through oversampling by the sensor IC

Parameters:

ut	parameter ut read from device

Returns:: temperature in steps of 1.0 Pa

See also:: bmp085_read_up()

Definition at line 279 of file bmp085_bst.c.

char bmp085_get_reg	(	unsigned	char,
		unsigned char *	,
		unsigned	char
	)

short bmp085_get_temperature ( unsigned long ut )

calculate temperature from ut ut was read from the device via I2C and fed into the right calc path for either SMD500 or BMP085

Parameters:

ut	parameter ut read from device

Returns:: temperature in steps of 0.1 deg celsius

See also:: bmp085_read_ut()

Definition at line 233 of file bmp085_bst.c.

unsigned long bmp085_get_up ( void )

read out up for pressure conversion depending on the oversampling ratio setting up can be 16 to 19 bit

Returns:: up parameter that represents the uncompensated pressure value

Definition at line 372 of file bmp085_bst.c.

unsigned short bmp085_get_ut ( void )

read out ut for temperature conversion

Returns:: ut parameter that represents the uncompensated temperature sensors conversion value

Definition at line 328 of file bmp085_bst.c.

int bmp085_init ( bmp085_t * bmp085 )

BMP085_init

input : Pointer to bmp085_t output: - return: result of communication function notes :

initialize BMP085 / SMD500

This function initializes the BMP085 pressure sensor/ the successor SMD500 is also supported. The function automatically detects the sensor type and stores this for all future communication and calculation steps

Parameters:

*bmp085_t pointer to bmp085 device data structure

Returns:: result of communication routines

Definition at line 98 of file bmp085_bst.c.

char bmp085_set_reg	(	unsigned	char,
		unsigned char *	,
		unsigned	char
	)

int smd500_get_cal_param ( void )

read out parameters cal_param from SMD500 memory This routine generates parameters from bitsliced data

Returns:: result of communication routines
