Hi, been getting the Adafruit OLED 1.27" working! (Which is now responding (in python) and looks great, but, I need to create a better interface!).
I have of course visited the Adafruit website lots, just seen their page on the Dotstar APA102. These LED's are like the Neopixels according to Ladyada herself, and do not need the strict timings data stream of Neopixels!
This got me thinking, "Unicorn HAT 2" using these babies - no PWM/DMA/GPIO problems!
Also I have 2 Unicorn HATs, and have had both of them running off from one RPi, they of course show exactly the same as they are independently controlled by the chips on each board.
Is there a way to add another 8x8 matrix of LEDs that can be controlled by just one chip? So that each 8x8 matrix can be independently controlled. I am guessing (observed) that the LEDs snake over the board, and that somehow leads could be added to the end and then onto a board with just another snake of LEDs, and then another 8x8? Then dim the WS2812B with 64xN LEDs to control (lots of coding required of course).
