Hello everyone, i'm trying to acomplish this board http://electronics-diy.com/USB_IO_Board.php but can't find proper firmware for this build, maybe someono knows or have what i could to use? I has tryed few firmwares but nothing happens, i'm using PIC18F2455 with external osc 20Mhz. i'm new to this, tryed this circuit with program to flash different LED's, it works.
