Besides, there is a compensation function for leap year. 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.

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. Navigation menu Personal tools English Log in.

And if an error occured, some time 5ms should be waited before trying again. 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.

PaulS Brattain Member Posts: If I understand it this being on the I2C bus will need a separate address how dataasheet I find this or does it some how use the same address as the DS chip? But it looked like someone needed the code. daasheet

If it is omitted, is the Wire. Sign up or log datashwet Sign up using Google. I like your code, because it handles the page boundery for me.

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.

Finbarr 3, 1 9 If you look at the AT24CXX datasheetthe section datasheeg Page Write shows you how to speed up the writing of large amounts datashfet 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.

AT24C02 – SOIC8 – I2C EEPROM

When using a 5V power supply, the clock can reach KHz. 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.

But is the 50ms delay necessary? DS18B20 digital temperature sensor adopts single-bus technology, which can effectively reduce external interference and improve the measurement accuracy. This page has been accessed 6, times. I removed the delay of 50ms and att24cxx a delay of 5ms outside the loop, just before the return. You need to be careful.

RandallR, I think I found the problem. I don’t know what to test else, and I don’t understand the delay. I assume that 5ms is enough, since the datasheet of the AT24C64A says that writing is finished within 5ms. Yes, I am sort of still working on it.

Email Required, but never shown. If there are wrong read bytes, the return value is still normal.

Views Read View source View history. In that case, every Wire. I used ReadMem and WriteMem with a buffer. Without the delay of 50ms, the device could be busy.

Both while writing and reading. It has a totally different style of writing. That result is also good. So the return value doesn’t show an error.
