OV5640 driver:

This is my modified OV5640 driver for the CMOS camera that incorporates many image resolutions and/or image quality. You can take advantage of a higher FPS, Image Quality (Preview or Capture) or Window size, choosing the one that best fit your needs.

This is expected to work with reasonable quality for AW platform (32 bit and 64 bit).

Working window sizes and expected FPS (preview mode)

  • QSXGA: 2592x1936 (7.5 FPS)
  • QXGA: 2048x1536 (7.5 FPS)
  • 1080P: 1920x1080 (7.5 FPS, 15 FPS)
  • UXGA: 1600x1200 (7.5 FPS, 15 FPS)
  • UXGA: 1280x960 (7.5 FPS, 15 FPS)
  • 720P: 1280x720 (7.5 FPS, 15 FPS)
  • XGA: 1024x768 (7.5 FPS, 15 FPS)
  • SVGA: 800x600 (15 FPS, 30 FPS)
  • VGA: 640x480 (15 FPS, 30 FPS)
  • QVGA: 320x240 (30 FPS)
  • QCIF: 176x144 (30 FPS with some artifacts)

The OV5640 has been updated to work on M64 (https://github.com/avafinger/ov5640/tree/A64)
