Media Transfer Protocol

The CMX-USBH-MTP class driver enables users to implement MTP host functionality and access MTP enabled devices. A user-friendly API is provided for accessing the connected MTP devices. Since MTP is an extension of PTP, PTP devices can also be accessed using CMX-USBH-MTP.

Pictbridge

CMX-USBH-Pictbridge is a USB Add-On option which, when used in conjunction with CMX-USB-MTP, allows images to print directly from an image source without the need for a PC. This option also includes XML parser for encoding and decoding PictBridge protocol objects.

USB Host Bootloader

CMX-USBH-BL Host Bootloader provides the ability to update your product from a flash drive. With a footprint of less than 12K for code and under 2K RAM, the Host Bootloader is installed as a permanent bootstub and based on the developers' design, CMX-USBH-BL can automatically check the flash drive for a new image and upload it to the target.

CMX-USB Device
The CMX-USB device stack offers a wide selection of Add-On options including an HID class implementation supporting Human Interface Devices such as a keyboard, mouse or joystick, a full USB Mass Storage Class with optimized drivers for accessing MMC/SD cards or other devices, a CDC class implementation for supporting standard communications ports, Media Transfer (MTP) Class for portable media devices, Pictbridge Extension for MTP Class, RNDIS for Remote Networking, ECM for Ethernet Networking Control, Audio, MIDI, Printer, Personal Healthcare Class and a Bootloader. USB Mass Storage is fully compatible with CMX-FFS-THIN and CMX-FFS-FAT File Systems.

CMX is constantly adding new processors, for more information please contact us.
