Welcome comunity,
I am starting my electronics adventure and I have built a led matrix controler based on shift register like the one here:
http://arduino.cc/en/Reference/ShiftOut
It is working fine, but to make things more complex I'd like to control the matrix from PD using Firmata 2.1 which seems to have now control of ShiftOUT as mentioned here:
http://firmata.org/wiki/Proposals#ShiftOut
I am trying to send proper data to firmata from pduino examples with no luck.

I do not know how to understand this:

/* shiftIn/Out (uses 8-bit value)
* ------------------------------
* 0 START_SYSEX (0xF0)
* 1 shiftOut (0x75)
* 2 dataPin (0-127)
* 3 clockPin (0-127)
* 4 latchPin (0-127)
* 5 msbFirst (boolean)
* 6 bits 0-6 (least significant byte)
* 7 bit 7 (most significant bit)
* n ... (as many byte pairs as needed)
* n+1 END_SYSEX (0xF7)
*/

what should I send is something like: sysex 0xF0 0x75 9 10 11 ?? ?? ?? ?? 0xF7
too much question marks here....
pduino seems also not to understand hex values I am putting...

Please advice
