ADG2188 - I2C read protocol

Question asked by jgindc1 on Feb 19, 2014

I am attempting to us an I2C software package based on smbus read/write protocols. The write function works  but  the read function does not.

I observe, using an I2C bus monitor, that an smbus read only sends 1 byte at the write phase, not 2 as specified in the ADG2188 data sheet (2nd byte specifed as "don't care").

Any guidance will be gratefully received.
