Recently we got | Recently we got [[Blinkofant/LED-Display History|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<br /> | |||
300 panels equals 100.000++ LEDs :)<br/> | |||
<br/> | |||
1 panel full on needs 1.15 AMP @12V | |||
<strike>we don't know how to power them yet :)</strike><br/> | |||
<strike> we are probably going to use the trafo we got out of the old displays.<br/>needs drehstrom outputs 140 AMP 12V weights 40kg+</strike><br/> | |||
actually we might use a lot of ATX powersupplies<br/> | |||
There is a mailinglist for the blinkofant project see: blinkofant@lists.metalab.at | |||

On the last Panel of a row the following pins need to be connected on the output side: | |||
pin 1 -> pin 8<br /> | |||
pin 2 -> pin 3 | |||

Aktuelle Testfirmware für den Arduino liegt im GIT von 5uper.net ( git clone git@5uper.net:ledmatrix.git ) | |||
Ein clone des git-repos ist auf [https://github.com/parasew/blinkofanten github/parasew] | |||
Es gibt auch eine [http://pastebin.com/7GS76STv für avr-gcc angepasste Version]. | |||

</pre> | |||
this is the magic: | |||
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))); | |||
<pre> | |||
ein panel besteht aus 8*9 pixel (8 spalten mal 9 pixel) | |||
man schiebt 10 bits an daten rein für jede der 8 spalten | |||
9 bits an/aus pro pixel + 1 bit ob diese spalte blinkt | |||
wenn man das blinkybit gesetzt hat kann man auf pin6 eine | |||
clock anlegen die die blinkenrate vorgibt | |||

* ATTINY2313 .. das wird teuer | |||
* Logic IC für puffer und RX ? welche? | |||
* 2x mod8 buchse (rj45) ?! das wird auch teuer.. | |||
* kondensatoren | |||
* eventuell stecker für kabelverbinder zum led modul | |||
