Macro Definition Documentation

◆ FIFO_WMRK_SIZE

#define FIFO_WMRK_SIZE (8) /* Buffer 8 Samples. */

Definition at line 61 of file fxpq3115_fifo.c.

Referenced by main().

◆ FXPQ3115_DATA_SIZE

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

Definition at line 62 of file fxpq3115_fifo.c.

Referenced by main().

◆ FXPQ3115_SAMPLING_EXPONENT

#define FXPQ3115_SAMPLING_EXPONENT (0) /* 1 second. */

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).
