II2C interface return no ACK
I using a NHD-C0216CZ-FSW-FBW-3V3 Display with II2C interface to a atmel ATXMEG chip
there is some confusion related to the device address the spec sheet state the address is 7 bits (0111110) the it mention a r/w bit so I assume the the r/r bit is the LSB not MSB
I have tried many ways and I never get the ack
any advice??

Hello eoldynski,
Although the display's controller (ST7032) is capable of running I2C, the serial data pin is an input only and does not have the I2C pins brought out from the controller, unfortunately you would not be able to read from the display.
Hope this helps!0
