Did you try that? I have done a test with the 24C64A. Sign up or log in Sign up using Google. 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 datashdet and tells you when it’s finished.

DS18B20 digital temperature sensor adopts single-bus technology, which can effectively reduce external interference and improve the measurement accuracy. 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. Paging in this context allows operations such as writing or erasing to be carried out on dataseet number of locations at once instead of having to perform each one separately.

This page was last modified on 11 Juneat Also other examples at the Playground use a delay: 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.

Both while writing and reading. So that’s what I’m using now. 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. AT24C32, memory bit of which is 32K bit, can catasheet 8K bytes.

In what situations is it normally used? That would increase the code size, but reading and writing would be fast. Meanwhile, it can convert the measured temperature directly into a serial digital signal for computer to process. I like your code, because it handles the page boundery for me. at42cxx

Without the ag24cxx of 50ms, the device could be busy. You could add it to the Playground. In that case, every Wire.

I can’t generate any error. But is the 50ms delay necessary?

If you save it, you can go to you new created page by clicking on it, and start writing your page. 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?

I removed the delay of 50ms and added a delay of 5ms outside the loop, just before the return. Also, I do not know how to post to the “Playground”.

That result is also good. When you write, you write only to that page. And if an error occured, some time 5ms should be waited before vatasheet again.
