This was really easy to get going:
- Solder it
- Connect and configure 8ch expander (optional)
a. Set 64 pixels in general, AND in the channel config
b. Color order is GRB
- Define a 8x8 matrix in the mapper using the preset example
- Load any pattern that uses render2D()
I had never really seen the 2D/3D patterns before. The examples: cube fire 3D, plasma 3D, sinpulse 3D, fast pulse 3d, or honeycomb 3D all work on 2D and look really cool. “sound - spectromatix optim” also works if you have the sensor board connected.
I noticed my v1 WS2812 output expander has occasional sparkles (glitches) when Pixelblaze is set to a lower global brightnesses. This might be a problem with my soldering though. The newer APA102/WS2812 output expander is perfectly smooth at lower global brightness.
For $15 and 20 min this was pretty easy to get started with a matrix. That is, after I realized I had the 3-pin connector on backwards
