This link is the example of HTTP client using W5x00(iolibrary). ![](https://github.githubassets.com/favicons/favicon.svg) [GitHub](https://github.com/WIZnet-ioLibrary/W5x00-HTTPClient) ![](https://maker.wiznet.io/forum_uploads/wiznet/original/2X/a/a840830b35b5a451343b46f12635a39f6b640bf4.png) ### [GitHub - WIZnet-ioLibrary/W5x00-HTTPClient: The HTTPCleint Example for W5x00...](https://github.com/WIZnet-ioLibrary/W5x00-HTTPClient) The HTTPCleint Example for W5x00 using ioLibrary.

So, You have to add and modify this code with HTTP Client code. ### Reply 4 by hiren.tejani, 2021-03-16 when above example compile, i get following error for Wiznet-EVB. c:/nxp/lpcxpresso_8.2.2_650/lpcxpresso/tools/bin/…/lib/gcc/arm-none-eabi/5.4.1/…/…/…/…/arm-none-eabi/bin/ld.exe: Warning: alignment 2 of symbol `len' in ./src/ioLibrary/Application/HTTP_Client/httpClient.o is smaller than 4 in ./src/main.o c:/nxp/lpcxpresso_8.2.2_650/lpcxpresso/tools/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: HTTPServer_LPC11E36_LPCXpresso.axf section `.text’ will not fit in region `MFlash96' c:/nxp/lpcxpresso_8.2.2_650/lpcxpresso/tools/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: HTTPServer_LPC11E36_LPCXpresso.axf section `.bss’ will not fit in region `RamLoc8' c:/nxp/lpcxpresso_8.2.2_650/lpcxpresso/tools/bin/../lib/gcc/arm-none-eabi/5.4.1/../../../../arm-none-eabi/bin/ld.exe: region `MFlash96’ overflowed by 63284 bytes c:/nxp/lpcxpresso_8.2.2_650/lpcxpresso/tools/bin/…/lib/gcc/arm-none-eabi/5.4.1/…/…/…/…/arm-none-eabi/bin/ld.exe: region `RamLoc8’ overflowed by 4468 bytes collect2.exe: error: ld returned 1 exit status make: *** [HTTPServer_LPC11E36_LPCXpresso.axf] Error 1 ### Reply 5 by irina, 2021-03-16 (in reply to reply 4) I will compile the project immediately and answer it as soon as possible. Can you please tell me if mcu (target) changes whether or not? ### Reply 6 by hiren.tejani, 2021-03-17 i just add TLS library to “HTTPServer_LPC11E36_LPCXpresso” example code and in that example MCU is LPC11E36. i try to upload sample project but it’s size is approx7Mb so i can’t upload. ### Reply 7 by becky, 2021-03-19 (in reply to reply 6) Hi, TLS cannot be uploaded to the W5500-EVB. Because there is not enough memory. M4 core was used in the GitHub link where the example was posted. W5500-EVB is not enough because it uses M0 MCU. ### Reply 8 by noneedname, 2022-05-24 Hi can I use this library for RP2040 ? I need to http request with RP2040 and W5500. ### Reply 9 by irina, 2022-06-15 I’m sorry I’m late We support the microypython and C.
