hi everybody!
well, using simple arduino uno (smd version), to set i2c communication hygrosens hyt 221 humidity sensor.
i trying change default address of sensor 0x28 0x30, leading tried code given below.. (attached)
when run code, serial monitor shows fine... says address have been changed , done.. when again run i2c scanner program in microcontroller, should ideally detect sensor @ new changed address surprisingly, detects sensor again @ default address = 0x28. address not changed in hardware.
this confusing.. can guys please me.. there wrong sketch used..? or missing in hardware part??
thank in advance!!
cheers
