Question to your question ? Why a 2nd I2C bus. I'm putting together lots of sensors and wonder if I should have 2 busses. Thinking about it . .
- The speed of an I2C should be enough to handle lots of devices.
- Additional devices probably means more wire and capacitance, but that could be addressed by a booster chip.
- 2 buses means a short will only bring down the devices on that bus.
Any thoughts ?
