OSC: Activate/Deactive button

[joky]

Hi,

is it somehow possible to evaluate the value of the OSC-message?
eg: /1/push1 ,i1 activates the button, /1/push1 ,i0 deactivates it.


If not, is there any workaround?

kind regards!

Hello,

Can you detail more what you're trying to achieve ?

Hi,

I want to send OSC messages from various clients (eg. home automation, android-tablet) to the QLC+. For the tablet I'm ok with toggling', but for home automation I'm not.


I'd like to integrate a chaser and some effects (moonflower) to our home automation server (HS). There is a On/Off switch to turn on the chaser, the HS can send the value 1 or 0 to QLC.
Toggling work fine (by sending 1), but if any UDP packet is lost or if anyone else is turning on/off the button in qlc+ the HS is doing wrong.


thanks for your fast response!!
regards

Solution 1: Replacing your toggle button with a slider in should work.

But I just realized I kinda broke sliders in 4.10.2: using sliders may erase the fadein speed of your rgbmatrices. You may use 4.10.1 if you experience this issue.


Solution 2: If you don't want to use 4.10.1 and if you build QLC+ from sources, you can patch the VCButton so a zero value will un-toggle it.

(I can tell you what you have to change exactly)

Solution 2 looks promising. I used the git-code anyway,..
Can you give me some instructions how to patch the vbutton?

[joky]

hmm... I think i found the code,..
trying to recompile,..

Nope, this won't do it

Try this:

Code: Select all

if ((isOn() && value == 0) || (!isOn() && value > 0))
    pressFunction();

(releaseFunction() is for buttons in flash mode only)

[joky]

works
thank you!

Without changing any of the code, I managed to get this going with using a 'stop all functions' fade out string first, (triggered in a solo frame) then sending the function command that you want shortly after. Though I admit this isn't ideal as dropped packets or packets sent from other sources could change things, but the command sent from the automation panel has essentially turned into an, 'only on' button.
