The output data comes from consecutive address- es, with the internal address counter automatically incremented after each byte output. If you only want to read from the chip then just power it from the 3.

24C64 Datasheet, PDF – Alldatasheet

In reply to Clemens Ladisch:. Sep 20, 9: If this is all nonsense to 24f64 then you probably ought to buy a 3. To use it from the Pi you’d need to supply power from the 5V and ground pins. Any tips on getting something out of it? If you do not understand how your existing code relates to the characteristics of the 24C64, you will not understand how to use the 24C04 either.

Anyway thanks for mind blowing knowledgeable lectures. This isn’t a satisfying dwtasheet, of course, but it is the maximum you can get for this little input.

I see that you work with data address directly, but this must be ORed with 0x corresponding to the bits for I2C addressing. Tell me after trying with the library. Thanks for reply Clemens Ladisch, My code is working correctly without any trouble with 24C64, but not with 24C Anyway your chip doesn’t differ by the others I’ve used.

You definitely know more than me, but in your previous post you wrote 0. And if you want to connect more than one eeprom, you can buy the pcb of Bank. I actually moved commented code my experiments into that main.


Hi, I’ve read now your question. I’m making an immobiliser feature for my motorbike-comp via a usb-like key containing the eeprom.


I wrote my problem here to get support not lecture. I’m datwsheet that’s what it means as there’s no documentation. Home Questions Tags Users Unanswered.

Then, the process is delivered to the wire library that do the low level work to manage I2C bus.

The same cannot be said for reading.

24C64 Datasheet(PDF) – Microchip Technology

You decided to keep your code secret both the old one and your 24f64 at the new one. At a minimum I’d check the voltage on the SDA output of the chip. Do you have another question?

And you adtasheet your main haven’t a return value. Its very easy to give lecture guys. Clemens is absolutely right – if you request help you also have to give some information to work with.


Due to the holidays, responses may be delayed. For some reason if I use “void loop ” things work, if I use “int main ” things don’t.

Ask a related question Ask a new question. It only needs a higher voltage if you want to write to the chip.

About the fact you can’t read by byte: I have always had a special interest in electronics and communication. Please, try to see dztasheet the project Bank 1. It turns out I can’t even write to the eeprom. So if i power the chip with 3. Already after the third post, I got the impression that this is a “do my homework quickly” request.

TI is a global semiconductor eatasheet and manufacturing company. My sensation 246c4 that you can’t read simly because you have datashet somewere else were you are thinking Datxsheet is no need to get mad now.
