There are 32 items available. Get the item you ordered or your money back. If the pin is high 5V and the address is in the top bytes, the write is ignored. Seller assumes all responsibility for this listing. This function takes three arguments, the device address the disk1 variablethe memory address on the eeprom and the byte of data you want to write. 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.

The next three bits A2,A1,A0 are the important bits that we can change so lets look at the simple table below to see what address the chip will have depending on what we set these pins to. Using the image above as a guide lets begin to wire the chip.

Learn more – opens in new window or tab. See other items More Lets say we want to write to address location 20, which is in binary. Next we start off just like we did with the write function by starting the process with beginTransmission and then we send the address we want to access; this works exactly the same way as the write function.


This excludes weekends and public holiday. Serial Clock Input WP: The seller hasn’t specified a postage method to United States.

The next argument is the address on the eeprom you want to write to and as stated above can be between 0 and 32, Then connect the SCL pin 6 to pin 5 on the Arduino.

We need to send the MSB Most significant bits first so we have to shift our address to the right eight bits. Time to move on to software! No additional import charges on delivery.

After our data and power pins are connected we have four left on 24LC chip, the WP pin and the three address pins. Add to Watch list. Immediate payment required for this item. Next we have to send the address on the eeprom we want to write to.

Some areas may incur additional costs 4 Please ensure you have a valid contact phone number registered with Ebay, I will pass this number onto the Carrier for delivery. International postage paid tamel Pitney Bowes Inc.

With the address pins connected the hardware part of this tutorial is complete and every pin of the 24LC should be connected to either Vcc, GND or the Arduino.

Postage cost can’t be calculated. Address bit 0 A1: May not post to United States – Read item description or contact seller for postage options. 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.

This means our 24LC chip gets the address and then which tells it to store the next byte in address location 20,
