Demonstration
ArduCAM provides a full demonstration for the OV2640 camera module on the Arduino platform. Please download the examples from Github.
Example ArduCAM_Shield_V2_Camera_Playback.ino
It will turn the ArduCAM into a real digital camera with capture and playback functions.
1. Preview the live video on LCD Screen.
2. Capture and buffer the image to FIFO when the shutter pressed quickly.
3. Store the image to Micro SD/TF card with BMP format.
4. Playback the capture photos one by one when the shutter button holds on for 3 seconds.
This program requires the latest ArduCAM library and ArduCAM Shield_V2 ArduCAM shield and use Arduino IDE 1.6.8 compiler or above.
Example ArduCAM_Shield_V2_Digital_Camera.ino
It will run the ArduCAM as a real 2MP digital camera, provide both preview and JPEG capture
The demo sketch will do the following tasks:
1. Set the sensor to BMP preview output mode.
2. Switch to JPEG mode when the shutter button pressed.
3. Capture and buffer the image to FIFO.
4. Store the image to Micro SD/TF card with JPEG format.
5. Resolution can be changed by myCAM.OV2640_set_JPEG_size() function.
This program requires the latest ArduCAM library and ArduCAM Shield_V2 ArduCAM shield and use Arduino IDE 1.6.8 compiler or above.
Example ArduCAM_Mini_Video_Streaming.ino
It will run the ArduCAM as a real 2MP digital camera, provide both preview and JPEG capture
1. Set the sensor to JPEG output mode.
2. Capture and buffer the image to FIFO.
3. Transfer the captured JPEG image back to host via Arduino board USB port.
4. Resolution can be changed by myCAM.OV2640_set_JPEG_size() function.
This program requires the latest ArduCAM library and Rev.C or Rev.C+ ArduCAM shield and use Arduino IDE 1.6.8 compiler or above.
5. Use ArduCAM host v2 application to capture, view and save pictures.
