Sign up using Facebook. The device will not respond to the address that is being set dynamically. Are you being confused by the common mistake that many people make where they treat the address of an I 2 C wrongly? TurboJ The chip says the following: But my suggestion would to directly connect them to ground or VCC for the addressing scheme.
Can you explain what hardwiring is? Then when you want to write to the part use an address byte of 0xA0 and when you want to read use an address byte of 0xA1.

Atmel Corporation makes nowarranty which is detailed in Atmel ‘s Terms and Conditions located on the Company’s web site. Can’t change the values dynamically. It will answer to address that was set up before powering up. Then the address byte that you use to write to the third chip would be 0xA4 and the address byte for reading the second chip would be 0xA5.
It connects the SOT package pins to the same signal position of the 8 pin DIPmechanical and electrical connections are supported by this adapter. Then the address byte that you use to write to the second chip would be 0xA2 and the address byte for reading the second chip would be 0xA3.
Also be aware that the A0 to A2 pins on the device package are meant to remain static in a design. Email Required, but never shown. Full 2K Array 24C04 1. A2 are used for creating the address. Instead the three bits that you supply out on the interface in the device address field must match the hard strapped values on the pins in order for the device to be selected. This device is not recommended for new designs.
In figure 4 they refer to the address as an 8-bit quantity:. This output is from I2C scanner.

So for example you keep A0: It considers the value of the A0,A1 and A2 before the power up and sticks to it till reset.
In Arduino, the function that does this is digitalWrite.

MaNyYaCk 6 The Company assumes no. In figure 4 they refer to the address as an 8-bit quantity: When you say that you are “writing” to the pins this does not make clear exactly what you are doing.
Is there something else I need to do?
