If 24v64 do not understand how your existing code relates to the characteristics of the 24C64, you will not understand how to use the 24C04 either. Did you make a mistake and what you said is wrong or am i wrong? There is a difference between the chip power supply voltage and dafasheet voltage needed to be seen as logic high and logic low by the chip.

How do you expect anybody to be able to help you? I datasueet you try re-reading the specs. All content and materials on this site are provided “as is”. Tell me after trying with the library. Clemens is absolutely right – if you request help you also have to give some information to work with. If this is all nonsense to you then you probably ought to buy a 3.

The same cannot datasheey said for reading. Why don’t you use the MSP’s communication module? Then, the process is delivered to the wire library that do the low level work to manage I2C bus. Can you please provide me a working code for 24C We are glad that we were able to resolve this issue, and will now proceed to close this thread.

This isn’t a satisfying answer, of course, but it is the maximum you can get for this little input. What is that define of 80 in your code?


The addressing of eeprom is not so simple, I saw, and I needed a lot of works to understand exactly the method. Which you have not shown. Sign up using Facebook. Its very easy to give lecture guys. Hi I’m sure that the read and write procedure must be the same, because the only thing that do at24c library is the evaluation of the datsheet.

Already have a hash check that works, just need to figure out how to turn off the arduino if the hash-check fails. Can you send me a little piece of code for reading and writing and a link to the datasheet of your device?

Ask a related question What is a related question? I am using the library you linked to as the 24c64 datasheet seems to ask for what the lib says sometimes For write: Suman, the chance that someone has exactly the code you need is very little.


I see that you work with data address directly, but this must be ORed with 0x corresponding to the bits for I2C addressing. But these two chips are not compatible different number of address bytesso it’s no surprise that the same code would not work.

Sep 19, 8: The output data comes from consecutive address- es, with the internal address counter automatically incremented after each byte output. Anyway thanks for mind blowing knowledgeable lectures. The trick to shift-left 16 bits and after the OR shift-right concerns the creation of the correct addressig.

There are errors in your code. Sign up using Email and Password. To write to the chip you need to take both into account as well as the write select pin. I had the chance to start working in the era of the first Personal Computers, just few years before their massive introduction, and very soon I started acquiring http: Read the datasheet of Atmel AT24C, that’s clearly explained in the chapter “device addressing”. Please, try to see if the project Bank 1.

In reply to Clemens Ladisch:. Thanks for your help.

But the specs say it needs 0. Further posts reinforced that suspicion – especially dagasheet aggressive style when being averted TI is a global semiconductor design and manufacturing company.
