Re: eservice LCD

Dr. Trigon
So I gave it another try today, by trying to address it from an arduino uno. Again the "old" issue of contrast (no pixels/dots visible). Looking at the example code (PHP) does not help too much as I do not understand how to manipulate single pins e.g.

(I did not check with owfs today as there is no new patch.)

So I see 2 possible ways to somehow continue on this as I think this is a nice display.
1. I will try to contact the manifacturer for some support to us
2. I can spend my display - as I cannot use it - and send it to Jan (?), if that is ok and helpful

Other suggetions are very welcome.

Greetings

Hi Jan

I am looking for a possiblity to wirelessly attach 1wire slaves to my bus for quite some time.
The Arduino Yun can act as a wifi client and connect to other wifi nets [1]. Also an Arduino can be used as a 1wire master by setting up OneWireFirmata [2]. Do you see any chance to make that working? To get something like a "wireless LinkHubE"?

Hi Jan

After long time I got around to play with 1wire some bit again.

I would like to give this LCD another try as I feel we must be close to a solution. What is the most simple way to get the code and test this (e.g. on a raspi)?

Thanks and Greetings

Download the v3.2p1 release and apply the patches I sent on 2016-07-05.
They should still match.

We could debug it further then.

Kind regards

The Arduino Yun's main processor runs an OpenWrt derivative.

Owserver is available as a package for newer OpenWrt Linux
distributions, but only version 2.8p13, it seems. That would mean you
had to cross-compile it yourself to be up-to-date. Backporting to a
six-year old version doesn't make sense.


It would be much easier for you to use a Raspberry Pi Zero W because it
runs the Raspbian distribution which is more up-to-date. Hook up a
DS2483 to one of the I?C ports of the Raspberry or use the bitbanging
master. They are both supported OOTB.


(Personally, I think the Arduinos jumped the shark a long while ago.)


Kind regards

Jan

Take a look at the ESP8266 chip, available in a variety of configurations
very cheaply.

Using one for this purpose was discussed on this list here:
http://owfs-developers.1086194.n5.nabble.com/ESP8266-DS18B20-and-owfs-td12634.html

Best wishes,

Andrew
