> No, no address lines are exposed. The point is that I2C/SDA are not shared so I need five different pairs of SDA/SCL (or changing I2C/SDA pins of peripheral on the fly, as I mentioned, but not too happy about it). I am referring to the pins that select the match address, not SDA/SCL. I2C parts usually have 1 to 3 of them to specify 1 to 3 bits of the full 7 bit address that the chip will respond to. That hackaday reference talks about about using one of these address match lines like a "chip select." Driving different address match bits can make different parts respond to the same address, for example. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
