WTF? Recently we got these *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 :) Pinout 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 pin # function comments 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 (0...off, 1...on) clock for blinking of selected rows 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 (0...off, 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 Software Aktuelle Testfirmware für den Arduino liegt im GIT von 5uper.net ( git clone git@5uper.net:ledmatrix.git ) SPI.begin(); SPI.setBitOrder(LSBFIRST); SPI.setDataMode(SPI_MODE0); SPI.setClockDivider(SPI_CLOCK_DIV128); // biggest divider there is. SPDR = panelData[i]; while(!(SPSR & (1<<SPIF)));
