//////////////////////////////////////////////////////////////////////////////// // // Filename: usbi.h // // Project: XuLA2 board // // Purpose: This package attempts to convet a JTAG over USB based // communication system into something similar to a serial port // based communication system. Some differences include the fact that, // if the USB port isn't polled, nothing comes out of the port. Hence, // on connecting (or polling for the first time) ... there might be a // bunch of stuff to (initially) ignore. // // // Creator: Dan Gisselquist, Ph.D. // Gisselquist Technology, LLC // //////////////////////////////////////////////////////////////////////////////// // // Copyright (C) 2015-2016, Gisselquist Technology, LLC // // This program is free software (firmware): you can redistribute it and/or // modify it under the terms of the GNU General Public License as published // by the Free Software Foundation, either version 3 of the License, or (at // your option) any later version. // // This program is distributed in the hope that it will be useful, but WITHOUT // ANY WARRANTY; without even the implied warranty of MERCHANTIBILITY or // FITNESS FOR A PARTICULAR PURPOSE.
