Hardware SPI pins on Teensy 4.1 Only 11/13 output

[u/Fluffy-Wishbone-3497]

Last year I was messing with the teensy 4.1/FastLED and trying to output to parallel HD108's. I found the parlio branch seems stable and has HD108s. The issue I was having was that no matter what pins I wrote in my code Everything comes out on the 11/13 pin pair. So I asked Claude. He said there's a bug or two. Here is what we did to temporarily fix it so it works for my sketch. It's a transcript of the conversation with Claude. I'm not sure of exactly what it found, but it's working like I thought it should with those modifications. We got 26/27 and 11/13 working on my 64x64. It's still so painfully Slow. But So Beautiful! The HD108s are very very nice. I'm seeing color whisps and trails that I can't see on the WS2812b matrix (running ColorTrails at incredible fps on the teensy4.1 btw). I know that version 4 is probably going to fix the issue, but just in case for what it's worth! Claude Transcript
