Check possible I2C interference #27

Open gracelower opened 2 days ago

"I2C signal wires that run to sensor from electronics board are subject to interference from one another. When wires run immediately next to one another, we get data failures; when they are physically separated, the data are fine." --> Crosstalk issues; need to see if this issue arises in C3PO

Observed problem, or forecasted one? Not a bad idea to catalog potential pitfalls, but I don't anticipate this being a major issue for us. We'll only have one set of I2C wires from the controller package to the sensor package, and then, from there, the different addresses of the different I2C chips in the sensor package will handle parsing out data between sensors. Unless you've seen this in practice, keep in a very low priority category (in my estimation)!
