/** * @file cc3000_common.cpp * @brief Defines common functions/macros for the CC3000 library * @author Texas Instruments * @author Modified by Shawn Hymel (SparkFun Electronics) * * Changes to the original code are listed below: * * - Changed file name from *.c to *.cpp to force the Arduino compiler to * treat it as a C++ file * * - Added the following to allow for debugging: * #include * #include "../common.h" * * - Changed return value of STREAM_TO_UINT16_f to a more explicit conversion * from a char[] to unsigned short * * - Changed return value of STREAM_TO_UINT32_f to a more explicit conversion * from a char[] to unsigned long */ /***************************************************************************** * * cc3000_common.c.c - CC3000 Host Driver Implementation. * Copyright (C) 2011 Texas Instruments Incorporated - http://www.ti.com/ * * Redistribution and use in source and binary forms, with or without * modification, are permitted provided that the following conditions * are met: * * Redistributions of source code must retain the above copyright * notice, this list of conditions and the following disclaimer. * * Redistributions in binary form must reproduce the above copyright * notice, this list of conditions and the following disclaimer in the * documentation and/or other materials provided with the * distribution. * * Neither the name of Texas Instruments Incorporated nor the names of * its contributors may be used to endorse or promote products derived * from this software without specific prior written permission. * * THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS * "AS IS" AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT * LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR * A PARTICULAR PURPOSE ARE DISCLAIMED.
