| Intersil ISL29034 ambient light sensor device driver for Google nanohub. |
| |
| - Supported features: |
| |
| A. Report ambient light data |
| B. Data rates: 10 Hz |
| C. I2C protocol |
| |
| The device doesn't have an interrupt line, so 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: |
| |
| ISL29034_I2C_BUS_ID /* specify I2C Bus ID */ |
| ISL29034_I2C_SPEED /* specify I2C Bus speed in Hz */ |
| |
| If these macros are not defined in the current variant the driver forces a |
| compile-time error. |
| |
| An optional macro is available to specify the I2C address of ISL29034 device. |
| If the macro is not defined, the default value 0x44 would be used. |
| |
| ISL29034_I2C_ADDR /* specify device I2C address */ |
| |
| An optional macro is available to enable debug information: |
| |
| ISL29034_DBG_ENABLED /* Enable debug messages */ |
| |
| Example: |
| |
| /* |
| * Define platform/variant dependent ISL29034 device macros |
| */ |
| |
| #define ISL29034_I2C_BUS_ID 0 |
| #define ISL29034_I2C_SPEED 400000 |
| #define ISL29034_I2C_ADDR 0x44 |
