HTS221 environmental sensor device driver for Google nanohub.
- Supported features:
A. Report Humidity data
B. Different data rates: 1/7/12.5 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:
HTS221_I2C_BUS_ID /* specify I2C Bus ID */
HTS221_I2C_SPEED /* specify I2C Bus speed in hz */
HTS221_I2C_ADDR /* specify device I2C address */
Example:
/*
* Define platform/variant dependent HTS221 device macros
*/
/* I2C defs to be used when device is plugged on U4 slot */
#define HTS221_I2C_BUS_ID 0
#define HTS221_I2C_SPEED 400000
#define HTS221_I2C_ADDR 0x5F
If these macros are not defined in the current variant the driver forces a compilation
error.
