1-wire

Hi,
Does anyone tried to use 1-wire devices with Amilda? I've got DS18B20 digital thermometer and I'm looking for some info how to communicate with it.

Re: 1-wire

Hi,
You can connect 1-Wire Bus-master to the com port and compile the software to access the 1-wire sensors.

Software: http://owfs.org/

A good shop for prebuilt 1-wire components: http://www.fuchs-shop.com/de/shop/17/

Please keep us posted on how things work out....1-wire is cool  cool

Re: 1-wire

using owfs would be great but i'm not sure what hardware should I use and how connect it to the uart. In the meantime I decided to write own simple 1-wire implementation using gpio. And ... i'ts working. I put source code with short description here http://www.n-s.com.pl/Amilda/ds1820/ . Any suggestions and feedback are welcome.

Re: 1-wire

Hi Jerry,

The 1-Wire is so cool that i decided to make a complete MOD for the Moding thread.
I already compiled and tested owserver, owget and owwrite.
The other tools of the owfs project are not so interesting to me, for the moment anyway.

So my idea will be to megaMOD the router board and make a 1-Wire Master/4xHub web server Powered by AMiLDA big_smile cool
The MOD will be so big, that i will have to make a new source package for extra compiling. smile
I will document my progress on the MODing thread...

cu there wink

Re: 1-wire

Hi,

Just dropped by to tell you that i've been working for 2 weeks now on the mega 1-wire mod, and its looking goood  big_smile

I cleaned up the source code, freeing it from all the router features.
Configured and compiled a few modules from the owfs project. (owserver, owshell and ownet)
Modified just about everything to fit the new stuff that are needed for the MOD.
And all is working great  cool

At the moment i'm working on the web server...programing new functions that are needed to control the 1-wire sensor network.

So all in all, i'll be releasing the whole thing very soon.

...i'm sure learning a lot of C with this project  lol
