Hi Norfolk,
the state of ADDR (High or Low) defines which address of the I2C bus is used by BH1750: Low: 0V on ADDR: 0x23h High: 3,3V on ADDR: 0x5Ch If you don't set the voltage of ADDR then its state is undefined, i.e. it can be high or low or even toggle between both states. Here is a description how to use the BH1750 with a Raspberry Pi: https://www.raspberrypi-spy.co.uk/2015/03/bh1750fvi-i2c-digital-light-intensity-sensor/ ------------------------------------------------------------------------ jd68's Profile: http://forums.slimdevices.com/member.php?userid=30795 View this thread: http://forums.slimdevices.com/showthread.php?t=112460 _______________________________________________ unix mailing list unix@lists.slimdevices.com http://lists.slimdevices.com/mailman/listinfo/unix
