I currently receive first byte (a) = 0, and second byte (b) = 2 always. Ambient light sensors are typically used to mimic the response of the human eye in some regard, or at least be applied to an electronic component that directly relates to the human experience under ambient lighting conditions. I have this program which successfully connects to the component but doesn’t receive any meaningful output.
#AMBIENT LIGHT SENSORS CODE#
I don’t understand what the command code byte and repeated start condition bit are. However, on page 7 of the datasheet it seems as if I need to send: start bit - address byte - write bit - command code byte - repeated start condition bit - address byte - read bit, just to obtain a data byte. Its still better than the screen gets dark every time. Why choose our ambient light sensors Human eye response Device-provided >99 human eye spectrum matching ensuring the best user experience. Renesas ambient light sensors can adjust a display’s backlight, which improves user experience and power savings by optimizing the display’s viewability. It is a photodetector that is used to sense the amount of ambient light present, and appropriately dim the device's screen to match it. They sense the environment lighting conditions and adjust the screens.
Just restart the computer, than click ESC to enter the BIOS, and then select something like 'built-in-devices', there you can find an option of the 'Ambient light sensor', and you can disable or enable it. An ambient light sensor is a component in smartphones, notebooks, other mobile devices, automotive displays and LCD TVs. Ambient light sensors are included in mobile phones, laptops, and handheld devices. I’ve been learning about the I2C library and have written some code that I thought would work. my work-around was to disable the 'Ambient light sensor' in the BIOS.
