I2c specifications

I’m wondering about the i2c specification for ER-301 and what its limitations are.

I would like to know if its possible to daisy chain different i2c devices on different addresses, does the ER-301 support this, or only 1 fixed address?

And, is it possible for bidirectional information on the i2c bus? E.g. if a unit on the ER-301 is able to send information via i2c to the external device. If this is not supported, is it possible to have this added in firmware?

i2c protocol does allow for bidirectional flow of data and daisy chaining devices (i think its like 128 devices on 7 bit addresses and 1024 devices on 10 bit). i have seen brian mention in other threads about the 301 that hes not fond of the idea letting the 301 become a CV computer. although theres really nothing stopping anyone from writing the code for a custom unit to make that happen, i dont think we’ll get any official support on this.
