WIZnet / Mbed 2 deprecated Camera_LS_Y201_HTTP_SDcard_file_server_WIZwiki-W7500

In this example, the image data acquired from the camera is stored on the Micro SD card and displayed through a web browser.

Dependencies:   Ethernet_Camera_LS_Y201_SDcard SDFileSystem WIZnetInterface mbed

Fork of HTTP_SDcard_file_server_WIZwiki-W7500 by justin kim

Prerequisite

In this example, the image data acquired from the camera is stored on the Micro SD card and displayed through a web browser.

To implement this function, you need a Platform board, network Interface board, camera module.

This example uses LS-Y201 Camera module.

  • WIZwiki-W7500 from WIZnet (Platform board and Ethernet I/F board)
  • LS-Y201 (Camera module)
  • Micro SD Card

Hardware Configuration

/media/uploads/Ricky_Kwon/camera_ls-y201.png

  • connect Ethernet Cable & USB Cable
  • connect Camera module

Software
