Working on 24C256 EEPROM 256Kbit / 32 Kbyte Serial Memory Data Storage on i2C Bus

I am using HAL Library for this purpose. Hi sir ; Thanks for your great work. This tutorial was originally posted on the 10kohms. Best regards from Spain! Your email address will not 24c256 eeprom published.

Thanks for your words, I hope the post helps you in your project. But if you send me some code that manages the IO lines, sure we 24c256 eeprom do an example to manage it.

Adding External I2C EEPROM to Arduino (24LC)

After our data and power pins are connected we have four left on 24LC 24c256 eeprom, the 24c256 eeprom pin and the three address pins. If you are using Arduino 1. Without the code, I 24c256 eeprom can give you some points seprom check.

First, ensure that after the last write you let at least 5ms before start reading. Does your sample use a software or hardware feature? This is a little confusing at first so lets look at the figure below to explain the address in a little more detail. 24c256 eeprom use as a reference the following Keil info: Hello Sir, I want to make a push button counter with the help of Arduino 24c256 eeprom and 24lc Then, the next byte will eepromm the data that you want to store.


After each byte you read, you must send an ACK, as you can see in the datasheet:. The first argument feprom the address of the device you want to write to, in our case we only have ewprom device disk1 so we pass this on.

Some of microcontroller have limited storage like Arduino it has only bytes 24c256 eeprom space compare to AT24C has Kb EEPROM will be very suitable for small amount of 24c256 eeprom storage or extending data storage for your microcontroller. Help me on this.

Leave a Reply Cancel reply Your email address will not be published. I have tested the code and it works great. Notify me of new posts by email. 24c256 eeprom of all, you can find the datasheet here. This site uses Akismet to reduce spam. First of 24c256 eeprom, thanks for read the blog and your interest on it.

The 24LC gets the data and writes the data ee;rom that address location. I am writing to memory from 24c256 eeprom 0x To 24c256 eeprom 6 characters, you need only six read operations, not seven.


See the address of the device below. It must tied to VSS for write operations.

Dear Sir First thanks a lot for your enthusiasm reply. If you can specify a bit more your troubles with the code, maybe I can help you a bit more. 24c256 eeprom this command, the memory is ready to start 24c256 eeprom read process. Device addressing This memory has 32KB of data. Other pin of this memory is the WP. We need to send the MSB Most significant bits first so we have to shift our address to the right eight bits.

Access Denied

So if I want to read all six characters, I have 24c256 eeprom perform read operation seven times. Check out our videos Follow us on: The Wire library eepgom you to pass an integer value so we could just make a bit-wise operation to device the integer variable 24c256 eeprom two bytes.

I2C 24c256 eeprom without Microcontroller! Answering your question, at first look the code seems ok. But it is not working I have connected 5. What is it 242c56 The next function requestFrom sends the command 24c256 eeprom that chip to start sending the data at the address we set above.
