(NOW WORKING) 'DS9490R 1wire usb adapter' working!

[wooly]

Problem with the DS9490R with LMCE.  Take a look at:

http://forum.linuxmce.org/index.php/topic,11328.150.html

And my chat with Techstyle: http://forum.linuxmce.org/index.php/topic,13040.msg94271.html#msg94271

I know RULE#1......12 months+?
Should I just bin it in parts bin and buy something else?

Regards

I do not have a 1-wire setup here, however, if somebody would send me a 9490R, and a couple of sensors, I could do the necessary work to debug the implementation.

Thom,

Actually, if you're able to make the C++ 1-wire device template more flexible, to accommodate more of the OWFS supported devices, that may solve the problem.  Right now it's hard-coded to expect a serial type device, which rules out all the network, i2c, and other types of OWFS bus masters <http://owfs.org/index.php?page=bus-masters>

In my case, I'd like to be able to use my Raspberry Pi as a networked OWFS control node.  I have some quick and dirty bash scripts running that do owreads into a variable, and then do a messagesend to a manually created device on the core.  Works well enough for proof-of-concept, and I can see the little Thermometer icon on the floor plans.

Just a thought...

Thanks!

Adding other adapter types is straightforward. The OneWire DCE device uses the OWCAPI (the C API from the OWFS project). The initialisation is done with the ow_init() call described here: http://owfs.org/uploads/owcapi.1.html#sect8
As you can see it takes the same device options as owfs(5), so besides serial devices it is also possible to specify a tcp connection to an owserver instance or usb devices (e.g. "usb"). ow_init() is called here: http://svn.linuxmce.org/trac.cgi/browser/branches/LinuxMCE-1004/src/OneWire/OneWire.cpp#L78

Code Select Expand


72         string port = TranslateSerialUSB(DATA_Get_COM_Port_on_PC());
[...]
78         if (OW_init(port.c_str())==0) {
[...]

the "port" string would need to be assigned with other owfs device options to achieve the wanted behaviour. So one could probably add a device parameter for a specific owfs init string. If that is set it would take precedence over COM_Port_on_PC.

A quick hack in the database to test if I'm right could look like this:
update Device_DeviceData set IK_DeviceData='usb'  where FK_DeviceData=37 and FK_Device=<id of your OneWire device>;

[hari]

Another option would be to just set the port string to "usb" when the DATA_Get_COM_Port_on_PC() is empty (because no serial port was set in the web admin):

Code Select Expand


72         string port = TranslateSerialUSB(DATA_Get_COM_Port_on_PC());
73             if (port == "") port = "usb";


That would not allow people to use tcp or other connection methods, but it would at least fail back to USB when no serial port is set..

this is untested but could work: http://svn.linuxmce.org/trac.cgi/changeset/27136

Hari,
How do I test/get this? sqlCVS update and or apt-get update?
Sorry newbie question's
Also I may have broke the 1wire template 2161, By making changes to device data section!
Is there a way to get it back to original?

Many thanks for your help

Wooly

[hari]

you can revert the local changes in the sqlcvs section of the web admin

[wooly]

I can now report success (adapter registered)
THANK YOU Hari
I did need to make changes to my device template 2161 though to get it to work:
Comm Method was saying 'RS232' so changed to 'Please select'
Under Device data - 37 com port on pc (string) - Default value - was still saying 'dev/ttyS0' so just deleted value and saved template then reload.....Thats it, it just worked

Sorry Thom was nearly ready to put DS9490R in post to you!

Wish I could code, tried programing a pic chip once in C+ gave up after 2weeks & used pic basic instead took 1day.

Respect,

Wooly

wooly,

why don't you put that DS9490R into the post to TSCHAK as a thank you for his work anyhow? Or visit http://www.linuxmce.org, and donate...

Just a thought

[wooly]

posde,

Was thinking I would make a donation as I don't have to buy a new 1wire adapter, although I am destitute at the moment that may change in the next few weeks, so watch this space...

As far as I know it was Hari that fixed 1wire....Thom just offered to if he got a DS9490R, so please read full topic thread.

Respect to all dev team.

Wooly

I read the whole thread. hari and tschak both deserve as much "Thank you"s as you can offer. Without them, there would be no LinuxMCE.

[hari]

he said thank you :-)

[Techstyle]

I can now report success Grin (adapter registered)

did any sensors show up?

[wooly]

Techstyle,
Yes just plug sensor in on parasitic reboot and there it was/is as child of 1wire
