Welcome to the Ambient light Sensor webpage.
[edit] Introduction
This webpage describes the Ambient Light sensor software development effort, mainly its current status and features planned in the road map.
ROHM BH1780GLI Ambient Light sensor supports I2C interface, and is most suitable to obtain ambient light data for adjusting LCD and keypad backlight. It supports wide range at high resolution
[edit] List of Features Supported
- On OMAP4
- Update/Read of power state i.e ON/OFF
- Read of luminance value in LUX
[edit] Design
- SYS FS Interface
- This is a generic Linux framework for device drivers and is available through /sys on the filesystem. It exports driver specific interfaces to user space.
- Ambient Light Sensor Driver
- This interfaces with BH1780GLI chip via I2C bus. I2C bus is used for accessing registers. The driver allows changing power state and read of Luminance value.
[edit] Feature Status Summary
Here is the summary of completed, ongoing and planned features in the Ambient Light sensor driver.
