HTTP sdcard file server WIZwiki-W7500ECO

Dependencies:   SDFileSystem WIZnetInterface mbed

Fork of HTTP_SDCard_File_Server_WIZwiki-W7500ECO by Bohyun Bang

Prerequisite

This Program is the example how to show SD card file list with web-browser for WIZwiki-W7500ECO.

To implement this function, you need a Platform board, network Interface board and SD card. Below are what we used.

  • WIZwiki-W7500ECO from WIZnet (Platform board and Ethernet I/F board)
  • SD card
