Improved explanation clarity.

Unfortunately I don't understand exactly what you mean, since the web page you added doesn't show two MCUs. Please can you add a diagram of your proposed configuration and explain why you mention a "special positive rail"? Do you understand the concept and challenges of I2C multi-master configurations? If you really want to have two MCUs on one I2C bus, you need to understand those concepts too (which are out-of-scope for this question). | |

| May 16, 2018 at 19:10 | comment | added | Divisadero | So this will work, but if two MCUs would would be connected, there would be special positive rail needed? There is no need in this case as it is alredy handled by the sensor circuit... | |
