BH1750FVI is an digital Ambient Light Sensor IC for I2C bus interface. This IC is the most suitable to obtain the ambient light data for adjusting LCD and Keypad backlight power of Mobile phone. It is possible to detect wide range at High resolution.It can be used in Mobile phone, LCD TV, NOTE PC, Portable game machine, Digital camera, Digital video camera, PDA, LCD display and so on.
LibDriver BH1750FVI is the full function driver of BH1750FVI launched by LibDriver.It provides continuous mode brightness reading, single mode brightness reading and other functions. LibDriver is MISRA compliant.
/src includes LibDriver BH1750FVI source files.
/interface includes LibDriver BH1750FVI IIC platform independent template.
/test includes LibDriver BH1750FVI driver test code and this code can test the chip necessary function simply.
/example includes LibDriver BH1750FVI sample code.
/doc includes LibDriver BH1750FVI offline document.
/datasheet includes BH1750FVI datasheet.
/project includes the common Linux and MCU development board sample code. All projects use the shell script to debug the driver and the detail instruction can be found in each project's README.md.
