Post as a guest Name. 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. Both while writing and reading. I assume that 5ms is enough, since the datasheet of the AT24C64A says that writing is finished within 5ms. When you write, you write only to that page.

So the return value doesn’t show an error. If there are wrong read bytes, the return value is still normal. But it looked like someone needed the code. You need to be careful. And if an error occured, some time 5ms should be waited before trying again.
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. Without the delay of 50ms, the device could be busy. In that case, every Wire.
When using a 5V power supply, the clock can reach KHz. 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. The address and data will be transmitted via a two-wire bidirectional serial bus, aat24cxx the chip can provide information such as seconds, minutes, hours, etc.
If you save it, you can go to datashdet new created page by clicking on it, and start writing your page. That would increase the code size, but reading and writing would be fast. Retrieved from ” https: It has a totally eatasheet style of writing. 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. The art of getting good answers lies in asking good questions.
This page was last modified on 11 Juneat RandallR, I think I found the problem. You could add it to the Playground. So that’s what I’m using now. Navigation menu Personal tools English Log in. I don’t know what to test else, and I don’t understand the delay.
The Playground is a wiki, and this a forum. If it is omitted, is the Wire. Did you try that? That result is also good. Email Required, but never shown. AT24C32, memory bit of which is 32K bit, can store 8K bytes. I used ReadMem and WriteMem with a buffer. Also, I do not know how datasheeh post to the “Playground”.
RandallR, Is this the only place where you publish you code? I put together a library to help me keep track of things. 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 datasueet single operation.
DS18B20 digital temperature sensor adopts single-bus technology, which can effectively reduce external interference and improve the measurement accuracy. Views Read View source View history.
