안녕하세요 W5500과 W5300은 HW에서 TCP통신 까지 지원합니다. 따라서 HTTP protocol을 SW에서 구현하셔서 사용하시면 가능합니다. 참고하실만한 링크 참조해드립니다. 아래링크는 keil기반의 WIZwiki-W7500 보드로 http client를 구현한 예제입니다. W7500은 W5500이 내장 되어있는 mcu chip입니다. github.com Wiznet/W7500/blob/master/W7500x_Library_Examples/Projects/Peripheral_Examples/WZTOE/httpClient/main.c /******************************************************************************************************************************************************* * Copyright �� 2016 <WIZnet Co.,Ltd.> * Permission is hereby granted, free of charge, to any person obtaining a copy of this software and associated documentation files (the ��Software��), * to deal in the Software without restriction, including without limitation the rights to use, copy, modify, merge, publish, distribute, sublicense, * and/or sell copies of the Software, and to permit persons to whom the Software is furnished to do so, subject to the following conditions: * * The above copyright notice and this permission notice shall be included in all copies or substantial portions of the Software. * THE SOFTWARE IS PROVIDED ��AS IS��, WITHOUT WARRANTY OF ANY KIND, EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF CONTRACT, * TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. *********************************************************************************************************************************************************/ /** ****************************************************************************** * @file WZTOE/Loopback/main.c * @author IOP Team * @version V1.0.0 * @date 01-May-2015 * @brief Main program body This file has been truncated. show original 아래링크는 mbed기반의 WIZwiki-W7500보드로 HTTP Server로 REST를 구현한 예제입니다…
