I currently receive first byte (a) = 0, and second byte (b) = 2 always. I have this program which successfully connects to the component but doesn’t receive any meaningful output. Sensors that detect distances over the speed of light (ToF) include the VL6180X, the VL53L0X and its bigger brother, the VL53L1X. I don’t understand what the command code byte and repeated start condition bit are. An ambient light sensor is one kind of component which is utilized in mobile devices, smartphones, notebooks, LCD TVs, and automotive displays. Its still better than the screen gets dark every time. 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. Simply stated, ambient light sensing (ALS) is the ability to measure the brightness of light incident on a surface. This helps conserve battery life and makes the screen more visible in different types of lighting. 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. my work-around was to disable the 'Ambient light sensor' in the BIOS. Samsung’s ambient light detection, or ALD, is a feature that uses sensors to automatically adjust the screen’s brightness to match the current lighting conditions. The sensor may come in different breakout board formats. It can measure a minimum of 1 lux and a maximum of 65535 lux. It outputs luminosity measurements in lux (SI-derived unit of illuminance). I’ve been learning about the I2C library and have written some code that I thought would work. Introducing BH1750 Ambient Light Sensor The BH1750 is a 16-bit ambient light sensor that communicates via I2C protocol.
