| I have a I2C devive that I'm having trouble setting up communication. The manufactures says the following in one place: "The address for unprogrammed OTP is 1100001 or 1100000. The LSB is set by the pin HW." And then gives this example in another place for changing the OTP: "0xC0(slave address);0x90(setOTP Parm);0xFF;0xFF;0xFA(OTP Address);
0x01(new address); So far all I get back is NAKs. What do you think I should use for the address? I2C r/w XX?

| Thanks Ringo. The controller board is here: The datasheet of the Trinamic TMC222 is here: I'm sure I'm just missing something obvious.

| I'm going through the data sheet now, but 1 thing I notoced is that the device will respond to an address of 0 (general call), have you tried that? Ringo
