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
