Anyway your chip doesn’t differ by the others I’ve used. 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. In reply to Clemens Ladisch:. Here’s what works I include the non-working main: It turns out I can’t even write to the eeprom.
Sep 19, 5: Thanks for your help.
No license, either express or implied, datasgeet estoppel or otherwise, is granted by TI. There is no need to get mad now. Clemens is absolutely right – if you request help you also have to give some information to work with. About the fact you can’t read by byte: I datashet see the sequential read mode but I thought it wasn’t possible as i’m a bit confused dayasheet the term ‘current’ in “sequential current read”. I read somewhere that 5V will destroy the I2C pins from the Pi.
Sep 20, 9: Further posts reinforced that suspicion – especially the aggressive style when being averted Can you please provide me a working code for 24C Why not debug the code you have to find out where the problem is located.
Please find my code, working correctly with 24C64 and abobe. Home Questions Tags Users Unanswered. I’ve found where i’m getting issues.
Already have a hash check that works, just need to figure out how to turn off the arduino if the hash-check fails. I am using the library you linked to as the 24c64 datasheet seems to ask for what the lib says sometimes For write: To terminate the stream of bytes, the bus master must not acknowledge the last byte, and must generate a Stop condition, as shown in Figure 9.
But the specs say it needs 0. Content on this site may contain or be subject to specific guidelines or limitations on use. I’m making an immobiliser feature for my motorbike-comp via a usb-like key containing the eeprom.
Obviously i will debug and will find the answers, it will take some time, but tried here to get it quickly.

This isn’t a satisfying answer, of course, but it is the maximum you can get for this little input. The output data comes from consecutive address- es, with the internal address counter automatically incremented after datashheet byte output.
For some reason if I use “void loop ” things work, if I use “int main ” things don’t.
I have always had a special interest in electronics and communication. Which you have not shown.

Did you make a mistake and what you said is wrong or am i wrong? Then, the process is delivered to the wire library that do the low level work to manage I2C bus. Sep 19, 8: Interfacing to my motorbike will be trivial as I already have a hidden toggle-switch that does the same thing.
Email Required, but never shown. The newly created question will be automatically linked to this question. I see that you work with data address directly, but this must be ORed with 0x corresponding to the bits for I2C addressing. Its very easy to give lecture guys.

That is NOT what I said. If you do not understand how your existing code relates to the characteristics of the 24C64, you will not datasheeh how to use the 24C04 either. I read about the difference in address etc between these two chips, but things are not clear. However there is a way around that problem. Post as a guest Name. Here’s the code I have Code:
