#159856 - From the data sheet Slave is 0xExxx0 Responding to: ???'s previous message |
From the data sheet, the Slave address is 0xExxx0 for Write and 0xExxx1 for Read. Or if you prefer the 7 bits and then shift left version: 0x70xxx.
The xxx is the hardware connections to A0/A1/A2 pins. So I can only assume that you have connected all these addressing pins to Vcc. 0xEE Write / 0xEF Read. It is more likely that you have them tied to GND giving 0xE0 / 0xE1 (or 0x70 in confusing 7 bit language) David. |
