This is a test program for Camera Module(C328, LJ-DSC02)
Dependencies: CameraC328 SDFileSystem mbed-src
Fork of Camera_TestProgram_2015 by
Prerequisite
This example stores the image data acquired from the camera on a micro sd card.
To implement this function, you need a Platform 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)
- LJ-DSC02 (Camera module)
- Micro SD Card
Hardware Configuration
- connect Camera module
Software
Init resolution and frame of image
#define USE_JPEG_HIGH_RESOLUTION 1 static const int CAPTURE_FRAMES = 1;
