Ideas for new Patterns (from LED Lamp)

SottNick · March 30, 2020, 2:30pm

All of these effects are open source.

Maybe this is interesting to someone …

Nice, thanks for sharing.
What kind of rgbpanels is it? Is it the flexible kind?
Is it possible to see what the build looks like?

SottNick · April 5, 2020, 8:40pm

There are build’s photos: ESP, IoT - WiFi лампа-будильник | AlexGyver Community

got it, I figured it might be neopixels and not rgbpanels.
This isn’t exactly the right place to post this, try https://www.reddit.com/r/FastLED/

I suggested that you can use the visual effects that are written for this lamp in your project.

SottNick · April 5, 2020, 9:01pm

The original goal of coming to your community was to find out the name of this effect:

Tell me please.

marcmerlin · April 24, 2020, 4:01pm

Try https://www.reddit.com/r/FastLED/ , they might know.

SottNick · April 24, 2020, 8:05pm

Why FastLED?!

I found this pattern on your video (11:07): SmartMatrix - Overview

But I can’t understand which of the files contains the program code for this effect.

marcmerlin · April 27, 2020, 3:31pm

I see, you should have given that detail and said it was from Aurora.
If you’re running Aurora, it should be simple for you to know what pattern you are running, if you can’t figure out it, look at serial output and/or add printfs.

More generally, please read How To Ask Questions The Smart Way when you ask questions, we can’t read your mind

Louis · April 27, 2020, 6:44pm

Sorry, I haven’t run Aurora in years, so I don’t know. You can try posting to FastLED as suggested, as there’s a big chance someone there (including Jason Coon the author) will read your message and know the pattern

SottNick · April 27, 2020, 8:40pm

Excuse me. I did not know that the LED-effect shown in the video on your site relates to another project. For some reason I thought that you know at least its name.

marcmerlin · April 28, 2020, 4:10pm

but honestly, if you have the code working, it’s trivial to get it to output what it’s running on the serial port and tell you what pattern is currently displaying.

SottNick · May 9, 2020, 9:04pm

Unfortunately, I have no way to run the entire code, and the count of patterns is large enough to adapt each for my ESP 8266 and to check. And I’m not at all sure that this pattern is in this version of the source code.

Louis · May 9, 2020, 10:30pm

I don’t think anyone in this thread is capable of running Aurora easily right now, I think Marc’s suggestion to try posting at FastLED on Reddit is best

marcmerlin · May 17, 2020, 10:53pm

@Louis I do have aurora demos ported to Framebuffer::GFX here:
FastLED_NeoMatrix_SmartMatrix_LEDMatrix_GFX_Demos/GFX/Aurora at master · marcmerlin/FastLED_NeoMatrix_SmartMatrix_LEDMatrix_GFX_Demos · GitHub
it’ll work on whatever backend you want.

SottNick · May 18, 2020, 9:23am

Thanks.
By the way, when I ported your effects, I found an error.

https://github.com/marcmerlin/FastLED_NeoMatrix_SmartMatrix_LEDMatrix_GFX_Demos/blob/master/LEDMatrix/Table_Mark_Estes/Table_Mark_Estes.ino

abs(cangle);
abs(sangle);

For the float type, you need to use the function fabs().

marcmerlin · May 18, 2020, 5:09pm

Thanks Scott. @lemuroid actually wrote this code (I ported it and made it work with my multi backend library).
Mark, any idea why you used abs vs fabs? See code:

          }
          
          
char readchar;
          
          
void loop()
          {
            hue += 1;//increment the color basis
            h = hue;  //set h to the color basis
            if (counter % shifty == 0) driftx =  driftx + cangle;//move the x center every so often
            if (driftx > (MATRIX_WIDTH - MIDLX / 2))//change directin of drift if you get near the right 1/4 of the screen
              cangle = 0 - abs(cangle);
            if (driftx < MIDLX / 2)//change directin of drift if you get near the right 1/4 of the screen
              cangle = abs(cangle);
            if ((counter + shifty / 2) % shifty == 0) drifty =  drifty + sangle;//move the y center every so often
            if (drifty > ( MATRIX_HEIGHT - MIDLY / 2))// if y gets too big, reverse
              sangle = 0 - abs(sangle);
            if (drifty < MIDLY / 2) {// if y gets too small reverse
              sangle = abs(sangle);
            }
          
          
  driftx = constrain(driftx, MIDLX - MIDLX / 3, MIDLX + MIDLX / 3);//constrain the center, probably never gets evoked any more but was useful at one time to keep the graphics on the screen....

lemuroid · May 19, 2020, 2:32am

i suspect I failed to use fabs because I had no idea it existed or that abs was going to be an issue. So, I learned something today.

The code seems to function despite this or does it? Anyway, with the exception of taking an introduction class 15-111 at Carnegie Mellon, I am a self taught programmer who has a tiny bag of tricks but uses them often.

SottNick · May 19, 2020, 9:27am

The following lines had to be added precisely because of this error.

driftx = constrain (…
drifty = constrain (…

The drifting of the center eventually stopped in the corner.

marcmerlin · May 19, 2020, 2:49pm

Don’t feel bad, I didn’t know about fabs either
