Prerequisite
This Program is the example how to show SD card file list with web-browser for WIZwiki-W7500.
To implement this function, you need a Platform board, network Interface board and SD card. Below are what we used.
- WIZwiki-W7500 from WIZnet (Platform board and Ethernet I/F board)
- SD card
Hardware Configuration
WIZwiki-W7500 Pin map
Software
SPI Initialization
main.cpp
SDFileSystem sd(PB_3, PB_2, PB_1, PB_0, "sd");
