OneWire slave interrupt based lib

Postby fari » Tue Feb 28, 2017 10:09 pm

Hello everybody!

I have migrated the library of Youen Neuoy to STM321f103 (Arduino). You have got the advantage, that the polling does not bloc your micro, since the onewire communication is interrupt based. The attached example simulates the DHT22 sensor
Some timing constants have to be adjusted, if you change your Arduino compiler options!
I have fixed one bug, which caused a total deadlock of the onewire network. Still there are few telegram errors (app. 1%)
Unfortunately I do not own a logic analyser and could not trace the cause of erroneous telegrams .

I have signed into gitHUB and will upload the library soon!

Wow

Thanks for posting

I2C slave is / was a noticeable gap in the core functionality
