Harold,
What type of UI are you actually trying to create for this?
You can do anim.run(threaded=True) but that as a ton of complications.
There’s a better way… Sadly this part is not well documented yet, though I’m currently working on it. But it’s not super complicated.
So, instead use our Projects feature.
The undocumented part is that there is a remote control feature for which you can see an example here:
https://github.com/adammhaile/BiblioPixelProjects/blob/master/SparkCon2017/1K.json
This will start up the animations and provide a web UI controller here: http://localhost:5000/
You don’t have to use the UI thought.
If you want to start the animation called GameOfLife call: http://localhost:5000/api/run_animation/GameOfLife
If you want to stop the animation, call: http://localhost:5000/api/stop/
If you want to set the brightness, call: http://localhost:5000/api/brightness/<0-255>
Absolutely read the projects docs linked above first. Once you have your head around that, each animation is defined like this:
{
"animation": {
"typename": "BiblioPixelAnimations.matrix.GameOfLife.GameOfLife",
"name": "GameOfLife"
},
"run": {
"fps": 15
}
}
The name field is what you’ll call out with the API. It must be unique.
The run field is the same things you’d use when calling anim.run() manually.
But all of this automatically runs threaded and lets you easily control it through the REST commands. For example:
import requests # pip install requests
requests.get('[http://localhost:5000/api/run_animation/GameOfLife](http://localhost:5000/api/run_animation/GameOfLife)')
That would run the animation block from above. You don’t really need to inspect the response. It’s just json. But unless you are having errors, it’s nothing useful.
You should be able to do most of what you mentioned. Only thing it doesn’t really cover is the speed. You can setup the same animation multiple times with different speeds? Eventually I plan to add an option for sending data to a running animation or change FPS on the fly.
Hope that helps.

I am relatively new to Python. If this question is more appropriate on a Python forum I will seek an answer elsewhere.
I want to start an animation and then go do other stuff while the animation runs.
In following the examples in Bibliopixel Animations the actual show starts when I run anim.run().
But I than stay in anim.run() until I interrupt out of it.
I did set up an KeyboardInterrupt exception so that on Interrupt I return to the main part of the program rather then crashing the program.
How do I let the animation run on it’s own while the main program continues to monitor other events?
As an example of what I want the main program to provide is a means for the user to:
- Enter a SPEED command to either slow down or speed up the animation
- Enter BRIGHTNESS command to increase or decrease the brightness of the animation
- Enter a PATTERN command to stop the current animation and start up another animation
- In addition the pattern animations are only a portion of the overall functionality of playing the “blinky things”.
- I want other commands to move the user on to other functions rather than just the animations.
Right now I am limited to having to have the user press to end the current animation.
I do provide for the user to get a clean exit. As I mentioned above I catch the KeyboardInterrupt. At that point I clear all the leds and return to the main program.
But, my real desire is that the animation plays while the user and the program interact on another level.
