Recently we got this *huge* LED walls.

We disassmbled the monster and now we got ~300 LED panels

Each of the 8*9 pixels consists of 5 LEDs = 360 red LEDs per panel
300 panels equals 90.000 LEDs++ :)

we don't know how to power them yet :)


  • POUT EQU CENTRO ;the leftmost module will be connected to the POUT-port
  • ATTENTION! The bit positions must not be changed!
  • 8V, 5V, 12V, GND are not equipped with pins

1 data/clock ? comes back out here (Rückleitung Schieberegister) wurscht
2 data/clock ? comes back out here (Rückleitung Schieberegister) wurscht
3 DatLoad EQU 0 ;data bit for loading data and control data wurscht
4 ClkRing EQU 1 ;clock for shift left the whole line CLOCK !!
5 ClkLoad EQU 2 ;clock for shift left & loading all selected modules wurscht
6 ClkBlink EQU 3 ;clock for blinking (, 1...on) selektrierte spalte blinken
7 ClkSteu EQU 4 ;clock for shift left & load control data from DatLoad wurscht
8 DatRing EQU 5 ;data bit for loading data during ClkRing DATA !!
9 Reset EQU 6 ;clear all control data wurscht
10 OnOff EQU 7 ;turn on/off the whole display (, 1...on) turns off ALL the LEDs when pulled to ground

When connecting ONE single panel the following pins need to be connected on the output side:

pin 1 -> pin 8
pin 2 -> pin 3
