The one I am currently using or the at24c library?

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 address. Post as a guest Name.

There is no need to get mad now. And if you want to connect more than one eeprom, you can buy the pcb of Bank. As long as the chip doesn’t actively drive SDA it should be quite safe to use with the Pi. If this is all nonsense to you then you probably ought to buy a 3.


m24C64 i2c eeprom

Did you make a mistake and what you said is wrong or am i wrong? My sensation is that you can’t read simly because you have addressed somewere else were you are thinking I don’t really have a need for more than one eeprom.

How do you find out the current address? Further posts reinforced that suspicion – especially the aggressive style when being averted Sign up using Email and Password.

Interfacing to my motorbike will be trivial as I already have a hidden toggle-switch that does the same thing. But these two chips are not compatible different number of address bytesso it’s no surprise that the same code would not work.

The only answer datzsheet can expect is something like: Can you please provide me a working code for 24C Sep 19, 8: This isn’t a satisfying answer, of course, but it is the maximum you can get for this little input.

Also why exactly are you multiplying the Input High Voltage with 3?

What is that define of 80 in your code? Can you send me a little piece of code for reading and writing and a link to the datasheet of your device? Mentions Tags More Cancel. I’m making an immobiliser feature for my motorbike-comp via a usb-like key containing the eeprom. Thanks for reply Clemens Ladisch, My code is working correctly without any trouble with 24C64, but not with 24C I’ve found where i’m getting issues.

We are glad that we were able to resolve this issue, and will now proceed to close this thread. I see that you work with data address directly, but this must be ORed with 0x corresponding to the bits for I2C addressing.
