WIZnet / Camera_TestProgram_2015

This is a test program for Camera Module(C328, LJ-DSC02)

Dependencies:   CameraC328 SDFileSystem mbed-src

Fork of Camera_TestProgram_2015 by Ricky Kwon

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

/media/uploads/Ricky_Kwon/camera.png

  • connect Camera module

Software

Init resolution and frame of image

#define USE_JPEG_HIGH_RESOLUTION  1
static const int CAPTURE_FRAMES = 1;
