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
