Samujas That result is also good. The Playground is a wiki, and this a forum. Finbarr 3, 1 9 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. If there are wrong read bytes, the return value is still normal. But it looked like someone needed the code. If it is omitted, is the Wire.

Samujas That result is also good. The Playground is a wiki, and this a forum. Finbarr 3, 1 9 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. If there are wrong read bytes, the return value is still normal. But it looked like someone needed the code.

If it is omitted, is the Wire. Among which, those of K-bit support serial CMOS E2PROM with I2C bus data transfer protocol, which are electrically erasable, datasehet for self-timed writing cycle including auto erase time of no more than 10ms, typical time of 5ms. 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.

Meanwhile, it can convert the measured temperature directly into a serial digital signal for computer to process. 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. Sign up using Email and Password. In what situations is it normally used? Paging in this context allows operations such as writing or erasing to be carried out on a number of locations at once instead of having to perform each one separately.

I have done a test with the 24C64A. If you save it, you can go to you new created page by clicking on it, and start writing datasheeg page. You could add it to the Playground. And if an error occured, some time 5ms should eatasheet waited before trying again.

I checked the return values of the Wire library, and was able to generate some errors. With simple interface, it makes data transmission and processing much easier. That would increase the code size, but reading and writing would be fast. Both while writing and reading. I like your code, because it handles the page boundery for me. So it is not the writing that needs a delay, but only the first read after writing. Yes, I am sort of still working on it.

Did you try that? The art of getting good answers lies in asking good questions. DS18B20 digital temperature sensor adopts single-bus technology, which can effectively reduce external interference and improve the measurement accuracy. It has a totally different style of writing. In that case, every Wire. I removed the delay of 50ms and added a delay of 5ms outside the loop, just before the return.
