Usage

tsl* at iic?

Overview

The tsl driver provides support for the TAOS TSL2560/61 light-to-digital converters that transform light intensity into a digital signal output. These sensors contain a broadband photodiode and an infrared-responding photodiode allowing the ambient light level to be determined, as experienced by the human eye. This illuminance (in lux) is made available through the sysctl(8) interface and can, for example, be used to adjust the backlight of LCD screens to lighting conditions.
