Sorry to ask again Richard, but I really don't understand this "WORD" story. I'm french speaking so I may not fully understand your explanation

In "i2cwrite sda,sck,$aa,$38,[1,30,52]", $AA (=EeCtrl) and $38 (=EeAddress) have BYTE sizes, no?

Do you mean the I2C command will transform the two BYTE variables in one WORD sized one?
