Hi everyone!
I just got my first Pixelblaze and wanted to test it with 1 meter strip of 144/m SK9822 (APA102) RGB LEDs and the ElectroMage 8x8 LED Matrix. Unfortunately I only got an unintentional flicker-fests so far.

Pixelblaze
Runs off USB. Seems to function properly as I can communicate with the unit easily through WiFi.
1 meter strip of 144/m SK9822 (APA102) RGB LEDs
Powered through external 5 VDC power supply with plenty of Amps
red wire > +5VDC, blue wire > -5VDC
yellow wire > Pixelblaze clock, green wire > Pixelblaze data
ElectroMage 8x8 LED Matrix
Powered through external 5 VDC power supply with plenty of Amps
Matrix data IN wire > Pixelblaze data
P I X E L B L A Z E S E T T I N G S F O R 144/m SK9822
LED Type: APA102 / DotStar
Pixels: 144
Data Speed: tried all options
Color Order: tried all options
P I X E L B L A Z E S E T T I N G S F O R 8 X 8 M A T R I X
LED Type: WS2812 / NeoPixel
Pixels: 64
Data Speed: tried all options
Color Order: tried all options
Please note that I’ve tried the LED-strip and the 8x8 Matrix separately, never simultaneously.
The result with both the LED-strip and the 8x8 Matrix unfortunately was the same, a constant flickering no matter what setting options or patterns I tried. I also programmed an RGB test pattern. The LED “somehow” responded, e.g. when I’ve sent RED, “most” of the LED kinda flickered RED but with all kinda multicolor fireworks in-between, etc…
Any idea if the settings or the wiring are wrong? Any leads?
Thank you in advance for your help!
