Vďaka za odkazy, ale nechápem aj tak ako to zapojiť.. Na mojom paneli mám 4 linky (A, B, C, E) a všade sa uvádza že by mali byť 5 (A, B, C, D, E). Tak niekde je chyba a práve preto mi to nejde.. Objednal som ten modul Adafruit RGB Matrix Hat, tak snáď to s ním pôjde.. Hoci už tomu veľmi neverím :/
Aj tak toto bol len prvý pokus, v pláne mám niečo takéto:
https://learn.adafruit.com/raspberry-pi ... ix-display
Navyše v spojení 6tich kusov toho 64x64 panela takže to budem potrebovať isto pomoc od skúsených ľudí tu na fóre.
Bol by som veľmi vďačný keby sa ozval niekto kto s tým už pracoval a vie ako na to.
Ešte som našiel toto:

Matrix Color Pins
Pi GPIO #5 - Matrix R1 (Red row 1) pin
This pin controls the red LEDs on the top half of the display
Pi GPIO #13 - Matrix G1 (Green row 1) pin
This pin controls the green LEDs on the top half of the display
Pi GPIO #6 - Matrix B1 (Blue row 1) pin
This pin controls the blue LEDs on the top half of the display
Pi GPIO #12 - Matrix R2 (Red row 2) pin
This pin controls the red LEDs on the bottom half of the display
Pi GPIO #16 - Matrix G2 (Green row2) pin
This pin controls the green LEDs on the bottom half of the display
Pi GPIO #23 - Matrix B2 (Blue row 2) pin
This pin controls the blue LEDs on the bottom half of the display
Matrix Control pins
Pi GPIO #4 - Matrix OE (output enable) pin
This pin controls whether the LEDs are lit at all
Pi GPIO #17 - Matrix CLK (clock) pin
This pin is the high speed clock pin for clocking RGB data to the matrix
Pi GPIO #21 - Matrix LAT (latch) pin
This pin is the data latching pin for clocking RGB data to the matrix
RGB Matrix Address pins
Pi GPIO #22 - Matrix A (address A) pin
This pin is part of the 1->16 or 1->8 multiplexing circuitry.
Pi GPIO #26 - Matrix B (address B) pin
This pin is part of the 1->16 or 1->8 multiplexing circuitry.
Pi GPIO #27 - Matrix C (address C) pin
This pin is part of the 1->16 or 1->8 multiplexing circuitry.
Pi GPIO #20 - Matrix D (address D) pin
This pin is part of the 1->32, 1->16 multiplexing circuitry. Used for 32-pixel and 64-pixel tall displays only
Pi GPIO #24 - Matrix E (address E) pin
This pin is part of the 1->32 multiplexing circuitry. Used for 64-pixel tall displays only. Present on newer “Rev C” HATs only. Requires minor soldering, explained on next page.
Ale, ja nemám na mojom paneli D, ale v špecifikácii sa píše že používa 1->16 multiplexing.. Ja uz z toho šaleny..
