I put together a library to help me keep track of things. Both while writing and reading.

I removed the delay of 50ms and added a delay of 5ms outside the dafasheet, just before the return. Yes, I am sort of still working on it. That result is also good.


I assume that 5ms is enough, since the datasheet of the AT24C64A says that writing is finished within 5ms. Sign up using Facebook.


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? Meanwhile, it can convert the measured temperature directly into a serial digital signal datasheeh computer to process.

I used ReadMem and WriteMem with a buffer. It has a totally different style of writing. So it is not the writing that needs a delay, but only the first read after writing. I like your code, because it handles the page boundery for me.

24C02P Technical Data

And if an error occured, some time 5ms should be waited before trying again. I don’t know what to test else, and I don’t understand the delay. But it looked like someone needed the code. DS18B20 digital temperature sensor adopts single-bus datasbeet, which can effectively reduce external interference and improve the measurement accuracy.

When you write, you write only to that page. Navigation menu Personal tools English Log in. In that case, every Wire. So that’s what I’m using now. Besides, there is a compensation function for leap year. datazheet


Finbarr 3, 1 9 EEPROMs such as the AT24CXX have a built-in controller to carry out write operations for you; datasheett just provide it with the data you want written and it does the work and tells you when it’s finished.

The Playground is a wiki, and this a forum. RandallR, Is this the only place where you publish you code? 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.
