| 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. |
