    Sending TTL Signals (case 472)

    Hello, I am working on sending TTL signals from DirectRT in order to control external LED's. Could you please give a list of ports through which DirectRT can send such signals? Much appreciated.

    Hi - DirectRT can easily interface with your PC's parallel port. This will give you control of at least 8 LEDs. Do be sure to properly current limit the outputs, as the parallel port is a bit fragile electrically. The folks at www.beyondlogic.org have some nice diagrams and sample schematics.
