Scrolling Text sensor node with new V_TEXT
-
Another experiment for the V_TEXT variable/ sensor. Including brightness & speed setting and special Alarm function.
A scrolling display to let the family now that the dog needs walking... nothing more than 1 nano, 8 (or whatever number) of displays with max7219 controllera radio and a few cables
Total cost: €18 (with 8 displays)in Domoticz:
Built around the very versatile "Parola" driver library(I will upload a video when I know how to .. ;-))

Wow, cool @AWI
-
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!
-
@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??
-
@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..
-
Thanx for the answer, I hope that too
-
found this library for scrolling effect https://code.google.com/p/arudino-maxmatrix-library/.
-
@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!
-
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.
-
@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.
-
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?
-
@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.
-
@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
-
You can send messages as done here? http://forum.mysensors.org/topic/1957/lcd-clock-and-text-sensor-node-with-new-v_text
-
@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.

@Hoffan you best read the instructions for the development branch. The syntax changed a little. I'm typing on a phone right now. Best to search yourself

How to convert a sketch to 1.6 is described here (until it has been posted somewhere more sticky..) :
https://docs.google.com/document/d/1NKq5uuNdnxF5jWnum7VT32mbKLjuvqlx2A5D1qQ-H3Q/edit#heading=h.t5sdmpn6jz2iBasically a few search/replace... The above sketch would look something like this (untested)

ive spent a couple of hours on this, and i cant get it to work. any help?
-
@AWI are you able to help me convrt this to1.6? i cant get it
-
Fixed a couple of thing in the sketch. Now it compiles on 1.6 but you have to install the MD_MAX72xx library which it uses.
-
Where did you put the new sketch??
-
I updated my post above.

Okey... Strange because i test to compile that i Dev Branch and i get this error

Now the compile is working...
Now i will test it in real

@Hoffan - how did you get on? Interested to know before I order some components
-
It didn't work all the way for me... And i didn't have the time to check whats wrong
It thing its some thing withe the display settings
-
Hi @AWI do you stil have this setup in use? I tried to convert this to 2.0 and hock it up but there is something wrong with the order of the LED elements. They are somehow scrolling in the wrong direction. With part of the code handles this? Might be that I have the wrong library for the MD_MAX72XX where did you get the lib?
-
Hi @korttoma I have it somewhere in the (large) pile of 'old and/or unfinished' projects
What I remember is that there are difference between the MAX displays in orientation. Below a picture off mine..
You can change the display type in the MD_MAX72xx.h file of the library.
From line #212 you can choose various display types (only select one). Have fun and let us know your progress..
-
Thanks @AWI , the back of my displays are identical to yours and removing the LED element reviles the MAX7219EWG driver underneath.
I will look in to the file you mentioned, maybe I can work something out.
-
Chose the FC-16 from the .h file and now it is working! Thanks again @AWI

Thomas, could/would you please share the 2.0 version of the sketch as i also want to use the max7219 modules with mysensors. I already tried them with the md_parola library examples and there are pretty nice animations and effects in there.
Any chances to use those effects other than the scrolling examples with a node red/mqtt gateway combination?

Sure I can do that, I will share it when I get home to the computer where it is located.

Hi,
I'm using this fantastic code as well. This is working on 2.0
Next step for me would be to be able to create an array with more messages, so that the display could cycle thru them.

@gus you beat me to it, nice job!
Sorry @Orkspalter I forgot yesterday but I'm sure the one @gus posted is quite similar.
Is there anyone out there using this setup that have a sketch that can handle scandinavian letters (å, ä, ö). I just get gibberish instead of the letters.

@korttoma here is the sketch I'm using, probably quite similar to the one @gus shared

@artur thanks for your example. I managed to make it show the time. Now I just need to figure out how to make it show the text also.

Sorry for hijack. I am trying to get domoticz to show text from a node but am not able to.
present(2, S_INFO, "Gate Open Reason");
[..]
MyMessage msg2(2,V_TEXT);
[..]
String reason = "blah";
send(msg2.set(reason));But domoticz only shows a 1. Probably missing something obvious?

@shabba Try without using "String" type use "char[x]" instead. In general you should try to avoid using this type in real time environments.
send(msg2.set("Blah"));should do the trick in first instance.

@AWI Derp! Looking at the headers that looks right! Will try a little later and report. Thanks!
-
I just did send(msg2.set(reason.c_str())); and it worked. Thanks @AWI
