Serial EEPROM AT24C02

If a total of eight 24C02’s are used in the design then each of the devices will have these three pins hard strapped in a different combination from the set of b, b, b, b, b, b, b and b. Do not send technical questions via personal messaging – they will be ignored.

Virgin Galactic — Commercial Space Flight. Then the address byte that you use to 24d02 to the third chip would be 0xA4 and the address byte for reading the second chip would be 0xA5.

Next time you call the I2C read routine, you give it an address, and again immediately say “have you got any data? Check your chips markings. Skip to main content.

For more details on different operations and addressing, refer interfacing 24C02 with It has a daat of memory size arranged in 32 pages of 8 byte eepdom.

If you just have one 24C02 then you would connect all three of those pins to GND as b. The data is transferred and received serially through serial data SDA pin. Sign up or log in Sign up using Google. Even the data sheet that you linked can lead to confusion in this regard.

Interface SD Hseet with Arduino. Email Required, but never shown. Post as a guest Name. Interface GPS with Arduino. Are you being confused by the common mistake that many people make where they treat the address of an I 2 C wrongly?

Sign up using Email and Password. In figure 4 they refer to the address as an 8-bit quantity:.

24C02P Technical Data

SPI Module of Arduino. This high-density System-in-Package SiP integrates controller, power switches, and support components. When data is to be read or write, first a start condition is created followed by device address, byte address and the data itself. Can you explain what hardwiring is? But my suggestion would to directly connect them to ground or VCC for the addressing scheme. Next, the byte or page address is sent followed by the data byte.

It hasn’t yet shert, so you return your unitialised variable “result”, shet the library kindly buffers the data from the I2C bus when it does arrive.

You give the I2C device an address, and then immediately say “have you got any data”? Vcc enables write protection. That’s why I said “write”. In this particular setup, at least.

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. What is Web Browser.

This data byte eeprrom to be written on or read by the microcontroller.
