Definition in file fxpq3115_altitude.c.

Macro Definition Documentation

FXPQ3115_DATA_SIZE

#define FXPQ3115_DATA_SIZE   (5) /* 3 byte Pressure/Altitude and 2 byte Temperature. */

Definition at line 35 of file fxpq3115_altitude.c.

Referenced by main().

FXPQ3115_SAMPLING_EXPONENT

#define FXPQ3115_SAMPLING_EXPONENT   (1) /* 2 seconds */

In FXPQ3115 the Auto Acquisition Time Step (ODR) can be set only in powers of 2 (i.e. 2^x, where x is the SAMPLING_EXPONENT). This gives a range of 1 second to 2^15 seconds (9 hours).
