| Feb 2, 2016 at 7:32 | comment | added | Nick Gammon♦ | My code was just testing talking to a couple of other Arduinos using the code on my I2C page - with modifications. I don't know about the 74LS151. Your original schematic in the question has 74HCT4051 on it. | |
| Feb 2, 2016 at 6:34 | comment | added | Mikael Patel | I think it is important to emphasize that 74LS151 cannot replace the HC4051 in the circuit above. The HC4051 is acting as a switch and the I2C slave device can drive the signal. If using a 74LS151 the clock signal can be multiplexed instead. The data signal is then common. The third alternative is to use a digital pin to control the MPU9X50 AD0 pin. | |

| Feb 2, 2016 at 6:26 | comment | added | Thomas | Oh great, @NickGammon ! :D You've given me hope to continue this project. But, can I ask you the whole code you used? I tried reediting the code I used with the one you added, and I'm still confused on where should I put the selectTarget you are telling me to do. Thanks. | |
