Scrolling Text sensor node with new V_TEXT

[billy123]

Wow, thats great !

Could you please post an AliExpress link to the displays you used ?

Regards,
Andre

I think i found them

Wow, I so want to build this!

[AWI]

@billy123 That would be the right one. You can use most of the max7219 driven display. Sometimes these are 90 deg rotated but that can be adjusted in the library. Have fun!

Will this work in Vera??

[AWI]

@Hoffan I don't know the abilities of VERA but since this (V_TEXT) is new functionality I expect it works only in Domoticz. I hope the functionality will be extended to the other controllers soon..

[Hoffan]

Thanx for the answer, I hope that too

[Dheeraj]

found this library for scrolling effect https://code.google.com/p/arudino-maxmatrix-library/.

[AWI]

@Dheeraj I have tried this library also but it did not suit my purpose. Only one type of display orientation is supported but it is easier to comprehend.

Umm, this is awesome! Looks like I have a tinker project coming up!

[popunonkok]

Looks great. Is it posible (Or do you think it will be) to sen dynamic values to the display from Domoticz? Like the temperature or soil moist procentage.

[AWI]

@popunonkok it is very possible. In fact this is what I'm doing. You need to work on the controller side. For domoticz you can use a lua time script which sends new text every x time. For long messages you will need to script a fifo with multiple text messages.

[GertSanders]

Is it possible to send text to the node without a request call from the node itself?

The example is not clear on this point and the json example only sets the text value within Domoticz, right?

[AWI]

@GertSanders Domoticz does not "push" the Text value when changed. The published sketch "asks" periodically for the Text value. What I do now is create a Switch (S_BINARY/ light) with function "New text available". This switch triggers the polling sequence.

[GertSanders]

@GizMoCuz : It would be nice to be able to define the text of the S_INFO sensor in de UI of Domoticz, instead of only via json. I'm not capable of programming that myself, but it would make the use of text easier. I already log all incoming SMS messages into my SMS connected sensor in V_TEXT and have it this way a nice view on what nodes are sending to my SMS passthrough node or what SMS messages are received into my MySensors network. I know Domoticz has it's own SMS interface, but my node is capable of switching on stuff based on directly received SMS commands, and with V_TEXT I can now follow what is happening without needing a serial connection to the node. I should be clear that I'm a big fan of Domoticz :-)

[Jager]

You can send messages as done here? http://forum.mysensors.org/topic/1957/lcd-clock-and-text-sensor-node-with-new-v_text

[AWI]

@Jager If your controller supports it you can. In Domoticz the text value is not pushed so you need to make a request for it.

What am i missing, Because i get this when i try to compile it

Arduino:1.6.5 (Mac OS X), Kort:"Arduino Nano, ATmega328"

@Hoffan V_TEXT is still in the development branch...

[Hoffan]

Okey, That can explain, Byt when i use the Dev Branch
I get this Errors
