I am starting my electronics adventure and I have built a led matrix controler based on shift register like the one here:
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:
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...
