MTP

This embedded USB Media Transfer Protocol (MTP) class driver can be integrated with HCC’s FAT, THIN, TINY, and SafeFLASH file systems. The file system appears as though it is a drive on a PC.

This class driver supports two protocols:

  • Media Transfer Protocol – used for atomic transfer of music and media files to/from portable devices. As a component of the Windows Media framework, MTP is associated with Windows Media Player.  
  • Picture Transfer Protocol (PTP) – used for atomic transfer of photograph files from digital cameras.
