A much simpler solution is to change your delay in the loop to 5ms, and add also a delay of 5ms to the other WriteMem function the byte write version.

But is the 50ms delay necessary? I assume that 5ms is enough, since dqtasheet datasheet of the AT24C64A says that writing is finished within 5ms.

The address and data will datassheet transmitted via a two-wire bidirectional serial bus, and the chip can provide information such as seconds, minutes, hours, etc. DS18B20 digital temperature sensor adopts single-bus technology, which can effectively reduce external interference and improve the measurement accuracy.

So the return value doesn’t show an error.

Retrieved from ” https: The art of getting good answers lies in asking good questions. If I understand it this being on the I2C bus will need a separate address how do I find this or does it some how use the same address datssheet the DS chip?

That would increase the code size, but reading and writing would be fast. By clicking “Post Your Answer”, you acknowledge that you have read our updated terms of serviceprivacy policy and cookie policyand that your continued use of the website is subject to these policies.

Finbarr 3, 1 9 Among which, those of K-bit support serial CMOS E2PROM with I2C bus data transfer protocol, which are electrically erasable, datasheeg for self-timed writing cycle including auto erase time of no more than 10ms, typical time of 5ms. RandallR, I think I found the problem. When using a 5V power supply, the clock can reach KHz. EEPROMs such as the AT24CXX have a built-in controller to carry out write operations for you; you just provide it with the data you want written and it does the work and dattasheet you when it’s finished.

In what situations is it normally used? In that case, every Wire. Also, I do not know how to post to the “Playground”. PaulS Brattain Member Posts: I can’t generate any error. I removed the delay of 50ms and added a delay of 5ms outside the loop, just before the return.

Also other examples at the Playground use a delay: That result is also good. This makes it dztasheet faster than giving it an address and a data value and waiting for that to be written then repeating the entire process for each additional value.

I don’t know what to test else, and I don’t understand the delay. I checked the return values of the Wire library, and was able to generate some errors. You need to be careful. With simple interface, it makes data transmission and processing much dahasheet.

I put together a library to help me keep track of things.


AT24C32, memory bit datasheer which is 32K bit, can store 8K bytes. RandallR, Is this the only at24cxd where you publish you code? If you look dayasheet the AT24CXX datasheetthe section on Page Write shows you how to speed up the writing of large amounts of data by giving it the start memory address followed by a full or partial page of data values, and it then writes the page as a single operation.

Yes, I am sort of still working on it. Did you try that? Without the delay of 50ms, the device could be busy. If you save it, you can go to you new created page by clicking on it, and start writing your page.

But it looked like someone needed the code. I used ReadMem and WriteMem with a buffer. Email Required, but never shown. So that’s what I’m using now. If it is omitted, is the Wire. If there are wrong read bytes, the return value is still normal. I have done a test with the 24C64A. The Playground is a wiki, and this a forum.

Both while writing and reading. When you write, you write only to that page. I like your code, because it handles the page boundery for me. So it is not the writing that needs a delay, but only the first read after writing.
