Mass Storage

CMX-USBH-MS allows you to connect a standard pen drive to your embedded system to exchange files with the hosts’ file system. The system allows the host to access the drive using the minimum possible RAM and ROM requirements and can be used with both integrated and external USB controllers. CMX-USBH-MS uses just the control channel endpoint and two bulk endpoints. CMX-USBH-MS is fully compatible with CMX-FFS-FAT and CMX-FFS-THIN Flash file systems.

CDC Class

The CMX-USBH-CDC enables the designer to provide a virtual USB serial port on the embedded target which acts as a standard serial port and can be accessed using simple, serial API functions. CMX-USBH-CDC is optimized to use minimal RAM and ROM and requires just the control channel endpoint and a single interrupt endpoint.

HID Class

CMX-USBH-HID Class driver provides support for Human Interface Devices such as a mouse, keyboard and joystick. Descriptor parser included.

Printer Class

The CMX-USBH-PL Printer Lite class provides support for printing from an embedded USB Host.

USB Host Bootloader

CMX-BL-FAT can be used as a standalone reliable Bootloader for any sector based storage media such as SD/MMC cards and can be used with CMX-USB Host and CMX-USB Mass Storage to create a Bootloader which can install a new image from a pen drive.
