Using Camera module, FTP Client on WIZwiki-W7500, send the image data to FTP Server.
Dependencies: CameraC328 SDFileSystem WIZnetInterface mbed-src
Prerequisite
This example send the image data acquired from the camera to an FTP Server.
To implement this function, you need a Platform board, network Interface board, camera module.
Available camera modules are C328, LJ-DSC02. Because the cameras listed above all have similar internal protocols.
This example uses LJ-DSC02.
- WIZwiki-W7500 from WIZnet (Platform board and Ethernet I/F board)
- LJ-DSC02 (Camera module)
- FTP Server(AL FTP)
- Micro SD Card
Hardware Configuration
- connect Ethernet Cable & USB Cable
- connect Camera module
Software
Init FTP Server information
static char ID[]={"abc"}; //Set FTPServer Login ID
static char PASSWORD[]={"123"}; //Set FTPServer Login Password
const char ftpServer_control_ip_addr[] = "192.168.1.2";
Caution
Must fix FTP server ip, id, pass
