Thinking out loud

Progress: Building the test rig

2018-04-29 workbench.jpg

Here we are, about to upgrade the test rig on my workbench.

Old Rig

Arduino Mega & 1-meter NeoPixel strip

The current build of witchlights-fastled.ino does not run on the Arduino Mega. It gives memory errors. I don't want to get bogged down with memory optimization at this point in the game. So I'm replacing it with an Arduino Due.

The Due I'm installing is a drop-in replacement module for the control board of the Witch Lights. That way, I'm testing on the exact hardware that will be in production.

The LED strip is a five-meter WS2812B addressible LED strip, with 30 LEDs/meter. Just like the Adafruit NeoPixel strips I used in production, except without the waterproofing. Which won't matter in my home workspace, I sincerely hope.

New Rig

Arduino Due and 5-meter NeoPixel strip

And that was fast.

The test rig is in place, and the WS2812B strip works fine.

Next up is creating a new Sprite animation subclass, editing its scanner routine to map to the animation that I was working on the other day.

Speaking of which, it looks like this exported into the arduino sketch format:

//                       1234567890123456789012345678901234567890123456012345678901
strcpy(afc_timing-test, "123456788                                                 ");

So that's some progress. Taking a break now.
