  • Add sanity checks and more meaningful error messages.
  • Allocate FatFS LFN buffer on stack (frees 255 heap bytes).
  • Move the FatFS and MSC buffers to main RAM (saves heap and allows DMA access).
  • Use DMA for SDIO transfers.
  • Remove framebuffer mutex (IDE reads images before snapshots).
  • Define pin aliases (P0..P8)/
  • Move LCD to built-in module.

Image processing:

  • Improved iris detection.
  • Edge detection, generic convolution, motion detection and GIF support.
  • JPEG compressor optimizations (70ms @QVGA 320x240) faster BinDCT and 2x2 subsampling.
  • Proper JPEG headers for Grayscale images.
  • Bug fixes in old integral image code and a new integral image using a moving window.
  • Set the number of pixels counted in each blob in imlib_count_blobs.
  • Simplify the image descriptor APIs, use a generic image.load/save/match_descriptor functions.
  • Add HQVGA resolution, and special digital effects support.
  • Support higher Grayscale resolutions (up to QVGA) for most algorithms.
  • Image processing functions accept paths to images on uSD.
