Datadheet you make a mistake and what you said is wrong or am i wrong? Further posts reinforced that suspicion – especially the aggressive style when being averted Sep 20, 9: Here’s the code I have Code: Ask a related question What is a related question? Interfacing to my motorbike will be trivial as I already have a hidden toggle-switch that does the same thing.

Also why exactly are you multiplying the Input High Voltage with 3? You decided to keep your code secret both the old one and your attempt at the new one.

The one I am currently using or the at24c library?

Anyway your chip doesn’t differ by the others I’ve used. Thanks for your help.

42c64 Questions Tags Users Unanswered. Which library should I use? My sensation is that you can’t read simly because you have addressed somewere else were you are thinking Trademarks Privacy Policy Terms of Use. Please, try to see if the project Bank 1. Found out I wasn’t using any pull-up resistors. There are errors in your code.

Read the datasheet of Atmel AT24C, that’s clearly explained in the chapter “device addressing”. I read somewhere that 5V will destroy the I2C pins from the Pi. Locked Cancel Do you have another question? I have always had a special interest in electronics and communication. Clemens is absolutely right – if you request help you also have to give some information to work with. You definitely know more than me, but in your previous post you wrote 0.


I’m making an immobiliser feature for my motorbike-comp via a usb-like key containing the eeprom. Suman, the chance that someone has exactly the code you need is very little.

This isn’t a satisfying answer, of course, but it is the maximum you can get for this little input. To write to the chip you need to take both into account as well as the write select pin. About the fact you can’t read by byte: Do you have another question?

I wrote my problem here to get support not lecture. If you have further questions related to this thread, you may click “Ask a related question” below. For some reason if I use “void loop ” things work, if I use “int main ” things don’t. So if i power the chip with 3. But the specs say it needs 0. At a minimum I’d check the voltage on the SDA output of the chip.


Already after the third post, I got the impression that this is a “do my homework quickly” request. That is NOT what I said. The trick to shift-left 16 bits and after the OR shift-right concerns the creation of the correct addressig. In reply to Clemens Ladisch:. It only needs a higher voltage if you want to write to the chip. Has anybody used this?

Hi, I’ve read now your question. How do you find out the current address?

I see that you work with data address directly, but this must be ORed with 0x corresponding to the bits for I2C addressing. Obviously i will debug and will find the answers, it will take some time, but tried here to get it quickly. I suggest you try re-reading the specs.
