If there are wrong read bytes, the return value is still normal. So it is not the writing that needs a delay, but only the first read after writing.

When you write, you write only to that page. Also, I do not know how to post to the “Playground”.


This makes it significantly faster than giving it an address and a data value and waiting for that to be written then repeating the datssheet process for each additional value. This page was last modified on 11 Juneat Views Read View source View history.

The address and data will be transmitted via a two-wire bidirectional serial bus, and the chip can provide information such as seconds, minutes, hours, etc. Email Required, but never shown. RandallR, I think I found the problem. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. If I datassheet 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 as the DS chip?

Post as a guest Name. You need to be careful. Also other examples at the Playground use a delay: If it is omitted, is the Wire. I checked the return values of the Wire library, and was able to generate some errors. That would increase the code size, but reading and writing would be fast. You could add it to the Playground.

If you save it, you can go to you new created page by clicking on it, and start writing your page. The Playground is a wiki, and this a forum.

Did you try that? But it looked like someone needed the code. Sign up using Facebook. Home Datasheef Tags Users Unanswered. With simple interface, it makes data transmission and processing much easier.

So the return value doesn’t show an error. Among which, those of K-bit support serial CMOS Datashedt with I2C bus data transfer protocol, which are electrically erasable, programmable for self-timed writing cycle including auto erase time of no more than 10ms, typical time of 5ms. Meanwhile, it can convert the measured temperature directly dataaheet a serial digital signal for computer to process. 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 tells you when it’s finished.

It has a totally different style of writing. I can’t generate any error. If you look at 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. Without the delay of 50ms, the device could at24cxc busy.

That result is also good. So that’s what I’m using now. I don’t know what to test else, and I don’t understand the delay.
