//////////////////////////////////////////////////////////////////////////////// // // Filename: wbsettime.cpp // // Project: XuLA2 board // // Purpose: To give a user access, via a command line program, to set the // real time clock within the FPGA. Note, however, that the RTC // clock device only sets the subseconds field when you program it at the // top of a minute. This program, therefore, will wait 'til the top of a // minute to set the clock. It can be annoying, but ... it works. // // // Creator: Dan Gisselquist, Ph.D. // Gisselquist Technology, LLC // //////////////////////////////////////////////////////////////////////////////// // // Copyright (C) 2015, 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.
