Hello,

i am trying to use the mbed in an one wire (dalles/maxim) enviroment as a slave. A humidity sensor should be conected to mbed which than acts as an e.g.DS2413 temp sensor on the one wire bus. The work to translate the humidity data to temperature data is not a problem. But providing slave functionality on the mbed is a problem for me.

Does anyone know of a similar project?

Ben

Hi Be,

Your project got me thinking, yes this could be useful. I have only played with 1-wire or iButton using standard parts, drivers and hardware, but this could open up the applications.

I did a search but found nothing and then expanded it.

The most useful was a similar PIC application, which by coincidence is for a humidity sensor! http://www.fabiszewski.net/1-wire-slave/

Another interesting article, but you will have to do a search and ask google to translate (an amazing facility!) is search http://robocraft.ru/blog/arduino/302.html and read the translation. From this I also found:-

http://translate.googleusercontent.com/translate_c?depth=1&hl=en&prev=/search%3Fq%3Dhttp://robocraft.ru/blog/arduino/302.html%26hl%3Den%26biw%3D1440%26bih%3D696%26prmd%3Dimvns&rurl=translate.google.co.uk&sl=ru&u=http://robocraft.ru/blog/arduino/124.html&usg=ALkJrhjlnrXHRUUXdolw2XMeaZUIKNANDA

which has some useful information.

http://arduino.cc/forum/index.php/topic,65706.0/wap2.html also deserves a mention and has some interesting chat and links, but no final product?

Not exactly what you are after, but a great 1-wire article and I also really like Circuit Cellar is at: http://itech.fgcu.edu/faculty/zalewski/CDA4170/files/1wire.pdf

Let us know how you get on and post your findings especially any code for mbed.
