24C64 Serial CMOS EEPROM
The same cannot be said for reading. In reply to Clemens Ladisch:. Has anybody used this? Ask a new question Ask a new question Cancel. Read the datasheet of Atmel AT24C, that’s clearly explained in the chapter datashheet addressing”. For some reason if I use “void loop ” things work, if I use “int main ” things don’t.
After the last memory address, the address counter ‘rolls-over’, and the device continues to output data from memory address 00h. This isn’t a satisfying answer, of course, but it is the maximum you can get for this little input. Found out I wasn’t using any pull-up resistors. I don’t find referrals to this value after the define. Anyway your chip doesn’t differ by the others I’ve used.
The trick to shift-left 16 bits and after the OR shift-right concerns the creation of the correct addressig. Home Questions Tags Users Unanswered. The output data comes from consecutive address- es, with the internal address counter automatically incremented after each byte output. Locked Cancel Do you have another question?
Tell me after trying with the library. Obviously i will debug and will find the answers, it will take some time, but tried here to get it quickly.
Thanks for reply Clemens Ladisch, My code is working correctly without any trouble with 24C64, but not with 24C If you have further questions related to this thread, you datasheeg click “Ask a related question” below. We are glad that we were able to resolve this issue, and will now proceed to close this thread.

My sensation is that you can’t read simly because you have addressed somewere else were you are thinking There are errors in your code. About the fact you can’t read by byte: If you have a related question, please click the ” Ask a related question ” button in the top right corner. Already have a hash check that works, just need to figure out how to turn off the arduino if the hash-check fails.

Hi I’m sure that the read datashete write procedure must be the same, because the only thing that do at24c library is the evaluation of the address. What is that define of 80 in your code? Do you have another question? I actually moved commented code my experiments into that main.

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: It hangs at the write. If you only want to read from the chip then just power it from the 3.

You decided to keep your code secret both the old one and your attempt at the new one. Here’s the code I have Code: There is a difference between the chip power supply voltage and the voltage needed to be seen datashfet logic high and logic low by the chip.
If you want somebody else to write the code for you, you have to hire him. To write to the chip you need to take both into account as well as the write select pin. I did see the sequential read mode but I thought it wasn’t possible as i’m a bit confused about the 246c4 ‘current’ in “sequential current read”.
Can you please provide me a working code for 24C Please find my code, xatasheet correctly with 24C64 and abobe.
