Just checking with I2C experts that if I run 100MHz I2C (default arduino setting, right?)
The maximum number of nodes is limited by the address space, and also by the total bus capacitance of 400 pF, which restricts practical communication distances to a few meters.
You should be fine. I would recommend using external pullup resistors instead of relying on the internal pullups.
So there are two masters and one slave connected to the I2C and the masters definitely don't talk together. I guess I can just connect the I2C pins together, right?
Quote100MHz I2CHe he, not in our lifetime I'm guessing that was a typo.There are chips (eg PCA9600, PCA9525, P82B715) that will drive I2C for a long way, the P82B715 states over 50 meters.They all drive about 10x the line capacitance the standard allows for.______Rob
I can't tell between K, M, G and T
