But it looked like someone needed the code. I assume that 5ms is enough, since the datasheet of the AT24C64A says that writing is finished within 5ms. In what situations is it normally used?
I put together a library to help me keep track of things. Yes, I am sort of still working on it. So it is not the writing that needs a delay, but only the first read after writing.
Also other examples at the Playground use a delay: So that’s what I’m using now. If it is omitted, is the Wire. Without the delay of 50ms, the device could be busy. RandallR, Is this the only place where you publish you code?

DS18B20 digital temperature sensor adopts single-bus technology, which can effectively reduce external interference and improve the measurement accuracy. Email Required, but never shown.
The art of getting good answers lies in asking good questions. You could add it to the Playground.
But is the 50ms delay necessary? This page was last modified on 11 Juneat Both while writing and reading.

When you write, you write only to that page. PaulS Brattain Member Posts: Navigation menu Personal tools English Log in. At24cxc Questions Tags Users Unanswered. Among which, those of K-bit support serial CMOS E2PROM 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.

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 as the DS chip?
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. Meanwhile, it can convert the measured temperature directly into a serial digital signal for computer to process.

Paging in this context allows operations such as writing or erasing to be carried out on a number of locations at once instead datxsheet having to perform each one separately. This makes it significantly 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.
This allows it to apply the correct timing and necessary number of write cycles to make sure the data is stored reliably while making the device last as long as possible.
Also, I do not know how to post to the “Playground”. Besides, there is a compensation function for leap year. That would increase the code size, but reading and writing would be fast. 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.
Finbarr 3, 1 9 Retrieved from ” https: It has a totally different style of writing.

In that case, every Wire. Sign up using Email and Password. I used ReadMem and WriteMem with a buffer. I like your code, because it handles the page boundery for me. Did you try that?
