LPS22HB environmental sensor device driver for Google nanohub.

• Supported features:

A. Report Pressure and Temperature data B. Different data rates: 1/10/25/50/75 Hz C. I2C protocol

This driver does not support the DRDy interrupt. Instead, a timer callback is used to read the data.

• Platform/variant porting:

The driver requires that following macros are defined in the variant.h file of the specific variant:

LPS22HB_I2C_BUS_ID /* specify I2C Bus ID / LPS22HB_I2C_SPEED / specify I2C Bus speed in hz / LPS22HB_I2C_ADDR / specify device I2C address / LPS22HB_DBG_ENABLED / Enable debug messages */

Example:

/*

• Define platform/variant dependent LPS22HB device macros */

#define LPS22HB_I2C_BUS_ID 0 #define LPS22HB_I2C_SPEED 400000 #define LPS22HB_I2C_ADDR 0x5C

If these macros are not defined in the current variant the driver forces a compilation error.
