In Arduino, the function that does this is digitalWrite. It considers the value of the A0,A1 and A2 before the power up and sticks to it till reset. And me not initializing the variable “result” is indeed not quite! A2 are used for creating the address. 24c2 Required, but never shown.
There are 32 x 8 words each of one byte. Skip to main content.
On top of that I have never been sure that it is even possible to dynamically change the strapped value on the A0, A1 and A2 pins of a 24C02 after it has powered up. Virgin Galactic — Commercial Space Flight.

MaNyYaCk 6 Do not send technical questions via personal messaging – they will be ignored. Choosing Battery for Robots.
It will answer to address that was set up before powering up. I understand perfectly your point, AWOL. Even the data sheet that you linked can lead to confusion in this regard. Thus here it is: Post as a guest Name. Can you give more information?
The device can be addressed serially by the software. You do not write the addresses; you hardwire them. But what if the data came from some sensor or so?
Next, the byte or page address is sent followed by the data byte. When data is to be read or write, first a start condition is created followed by device address, byte shheet and the data itself. For more details on different operations and addressing, refer interfacing 24C02 with Bi-directional pin for serial data transfer. Found 8 device s.
In the above setup, I knew it of course, as I myself wrote it. Sign up using Facebook. Can’t change the values dynamically. In this particular setup, at least.

This output is from I2C scanner.
Also be aware that the A0 to A2 pins on the device package are meant to remain static in a design. In figure 4 they refer to the address as an 8-bit shedt However, it doesn’t matter what I set these pins to. I speak for myself, not Arduino.
