64x64 SRYLED P2.5-2121-32S-JJ-V6 bought two panels from affiliate link from Youtuber Bitluni: http://s.click.aliexpress.com/e/bhQPhfeY

Running on D1 mini Wiring diagram from Witnessmenow

Chipset: Same as Maditnerd issue (119) - they had 32x64 panel

In order to check my wiring, I used set up two D1 mini and two panels powered by a computer power supply: pic of side by side. 20201010_110509

For my sketches, I use: PxMATRIX display(64, 64, P_LAT, P_OE, P_A, P_B, P_C, P_D, P_E); P_E is not grounded display.begin(32);

Out of the box, the Mario sketch is like so: mario default but adding display.setMuxDelay(1,1,0,0,0), a much better image (shown in mario side by side and below), but with a weird blue bar and a green sky and cyan Earth. I also have a blue bar at the bottom of my screen. code mario.txt mario_delayed

Ive tried all combinations of muxdelay from 0,0,0,0,0 to 1,1,1,1,1.

When I run the test.ino with PxMATRIX display(64,64,P_LAT, P_OE,P_A,P_B,P_C,P_D,P_E), display.begin(32); I get this (.gif sped up 3x) : code pattern test.txt

test

I get red, yellow yellow, but no white!

note that if I do not run display.setMuxDelay(1,1,0,0,0), after the fourth cycle of testing, the row becomes very erratic flickering on and off then the next line is ok, but still no white.

As I was typing this issue out I left the test running, on the 17th iteration (for both no mux delay and mux display) a blue line appeared first and then went magenta, white, white: patterntest_blue

Lastly, this is my double buffer test, with the weird blue box artifacts. doublebuffer

My goal is to get the aurora demo working, but that seems to not like when there is a mux delay.

Any help on this would be awesome! Thanks so much!

I also have this issue. Looking forward for a solution

LOL. It may be because the color mode of the upper and lower fields is different. I have this problem with the LED panel in my hand.
