I'm having a problem
... I'm trying to connect 2 I2C devices to one microcontroller , but with the same address, so with an Arduino UNO it is impossible. I've tried something not proper : to carry the power supply of each sensor with a digital pin to disconnect the device, but it appears that I can't do that : the devices doesn't respond if one is connected the ground.
So one solution is probably to connect my devices to an other board, as the Arduino DUE with to i2C connections. (I've one card that I can use.)
But the Arduino Due works at 3.3V, my sensors at 5V, I guess it's an issue... How can I interface them ??? Directly or should I use a logic converter ?
Thank you for your help (and sorry for my English
