Using the image above as a guide lets begin to wire the chip. This data byte is to be written on or read by the microcontroller. There are three address pins in AT24C02 for selecting a particular chip. There are 32 x 8 datashee each of one byte. After our data and power pins are connected we have four left on 24LC chip, the WP pin and the three address pins. Finally a stop condition is provided. Below is the entire tutorial code, scan over it and see if you understand it before I dive into datasheer each section does.

Finally we have to pass along the byte we want datasneet store. Since our eeprom chip has 32, address locations we are using two bytes 16 bits to store the address but we can only send one byte at a time so we have to split it up. Next we have to send the address on the eeprom we want to write to. Then connect the SCL pin 6 to pin 5 on the Arduino. The WP pin stands for write-protected and this allows you to control if data can be written to the eeprom or not.
We need to send the MSB Most dataaheet bits first so we have to shift our address to the right eight bits. The 24LC gets the data and writes the data to that address location.
This allows the chip time to complete the write operation, without this if you try to do 24cd2wpp writes weird things might happen. To illustrate this lets follow the steps below.
For more information please read http: This last bit is 1 for write and 0 for read operation. The data is read or written between the start and stop conditions on every transition of SCL from high to low.
Similarly for read operation the device address to be sent is 0xA0 With the address pins connected the hardware part of this tutorial is complete and every pin of the 24LC should be connected to either Dataxheet, GND or the Arduino. Next, the byte daatasheet page address is sent followed by the data byte. The device can be addressed serially by the software.
This variable is not required but it allows us to easily change the address we want to access without going through all of the code and replacing the value. Arduino based GPS receiver. The arguments it accepts are the same first two arguments the write function, the device address and the address on the eeprom to read from.

Bi-directional pin for serial data transfer. Time to move on to software! This means our 24LC chip gets the address and then which dataheet it to store the next byte in address location 20, Before we get into the software part lets hook up the 24LC chip up to our Arduino. For more details on different operations and addressing, refer interfacing 24C02 with This tutorial was originally posted on the 10kohms.
SPI Module of Arduino. If you are using Arduino 1. What is Web Browser.
Next we do a bitwise AND to get just the last eight bits. This high-density System-in-Package SiP integrates controller, power switches, and support components.
