    I've had a TLC5940 object in the Propeller Object Exchange for some time. The code could be made to be much faster and more efficient, but it has worked reliably for years. obex.parallax.com/objects/375/

    The pin wiring depends on your application. The TLC5940 object allows you to use any pin. When starting the object you specify which signals are which pins. Look at the TLC5940 data sheet and I think you will see similar names as used in the object start method.

    PUB StartTLC5940(_sclk, _sin, _xlat, _gsclk, _blank, _vprg, _dcprog)

    I just now noticed the title of your thread included "Basic Stamp". Obviously the code I linked to was for the Propeller, but I think you got that. The basics is to clock data out and then latch it in. A second task is a continuously clocking signal that counts to 1023 as the gray scale clock.
