The WP pin stands for write-protected and this allows you to control if data can be written to the eeprom or not.

The device can be addressed serially by the software. Interface GPS 24cd22wp Arduino. This means our 24LC chip gets the address and then which tells it to store the next byte in address location 20, There are three address pins in AT24C02 for selecting a particular chip. This allows 24cd2p chip time to complete the write operation, without this if you try to do sequential writes weird things might happen.

Below is the entire tutorial code, scan over it and see if you understand it before I dive into what each section does.

For more information please read http: 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. 24ccd2wp our data and power pins are connected we have four left on 24LC chip, the WP pin and the three address pins.

Before we get into the software part lets hook up the 24LC chip up to our Arduino. This tutorial was originally posted on the 10kohms. This last bit is 1 for write and 0 for read operation. We first call the Wire. 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. Virgin Galactic — Commercial Space Flight. SPI Module of Arduino. The data is transferred and received serially through serial data SDA pin.

The next argument is the address on the eeprom you want to write to and as stated above can be between 0 and 32, For the purpose of explaining how the address works we can ignore the Start and Acknowledge bits.

Time to move on to software! Supply voltage; 5V up to 5. Finally we have to pass along the byte we want to store.

This data byte is datasheeh be written on or read by the microcontroller. We need to send the MSB Most significant bits first so we have to shift our address to the right eight bits.

It has a 2Kbits of memory size arranged in 32 pages of 8 byte each. To illustrate this lets follow the steps below.

The 24LC gets the data and writes the data to that address location. Next, the byte or page address is sent followed by the data byte. Vcc enables write protection. 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.
