USB Circuit Question
My problem is I need to control a 7 segment LED circuit (currently on a breadboard, eventually on a PCB). The only option I have from my PC is through USB. The circuit I have built on a breadboard uses 7 segment LED's and 4206 decade counters. I have cut a USB cable in half, and am using the positive and negative leads to power the circuit. I have made multiple attemps at controlling the circuit through the D+ and D- leads, but have failed so far. Basically all I need to do is control the clock input to the 4206 decade counter.
I have made multiple attemps at controlling the circuit through the D+ and D- leads, but have failed so far.
Does anybody know if this is even possible using the D+ and D- leads from the USB? I will eventually attempt to control it through bash script, but don't want to waste my time trying to develop a driver for this circuit if I will not be able to control it.

createbddcircuit
CREATEBDDCIRCUIT(3) BDD FUNCTIONS CREATEBDDCIRCUIT(3)
NAME
createbddcircuit - creates a bdd circuit.
ORIGIN
This software belongs to the ALLIANCE CAD SYSTEM developed by the ASIM team at LIP6 laboratory of Universite Pierre et Marie CURIE, in
Paris, France.
Web : http://asim.lip6.fr/recherche/alliance/
E-mail : alliance-users@asim.lip6.fr
SYNOPSYS
#include "bdd101.h"
bddcircuit *createbddcircuit( Name, NumberIn, NumberOut, BddSystem )
char *Name;
long NumberIn;
long NumberOut;
bddsystem *BddSystem;
PARAMETERS
Name Name of the bdd circuit.
NumberIn Number of inputs.
NumberOut Number of outputs.
BddSystem The bdd system to work on.
DESCRIPTION
createbddcircuit creates a bdd circuit with the name Name, with NumberIn inputs, and NumberOut outputs. This bdd circuit will use the bdd
system BddSystem. If a null pointer is given, the default bdd system is used.
RETURN VALUE
createbddcircuit returns a pointer to the bdd circuit created.
EXAMPLE
#include "bdd101.h"
bddsystem *BddSystem;
bddcircuit *BddCircuit;
BddSystem = createbddsystem( 100, 1000, 100, 50000 );
BddCircuit = createbddcircuit( "hello_world", 10, 10, BddSystem );
...
destroybddsystem( (bddsystem *)0 );
destroybddcircuit( (bddcircuit *)0 );
SEE ALSO
bdd(1), resetbddcircuit(3), destroybddcircuit(3).
