Micro Digital Announces USB Stack Enhancements

Share Article

Micro Digital, Inc. has announced several enhancements to its previously announced smxUSBH(tm) USB host stack and smxUSBD(tm) USB device stack. Both USB stacks have been upgraded to comply with the USB 2.0 Specification. As a result, both stacks are now able to support low, full, and high-speed USB operations.

In addition USB On The Go (USB OTG) support has been added in the form of a new product, smxUSBO(tm), our new USB OTG stack. smxUSBO can operate with either smx USB host stack or smx USB device stack, or both. All three stacks are priced separately to afford users the greatest flexibility.

To support these deelopments a USB Enhanced Host Controller Interface (EHCI) driver has been added for the USB host stack. Also, an NXP (Philips) ISP176x driver has been added. Both support USB high speed (480 Mbps) operation. In addition, USB controller drivers are now available for most Freescale ColdFire, Atmel ARM, Freescale ARM, Sharp ARM, and STMicro ARM on-chip USB controllers. More are being added every month. These make Micro Digital USB stacks truly drop-in solutions. Demos are available.

All smx USB products have been designed from the ground up for embedded systems. They comply with applicable specifications and suppport all four USB data transfer modes (control, bulk, isochronous, and interrupt) and low, full, and high speed operation. USB host class drivers are available for mass storage drives, mice, keyboards, printers, and hubs. USB device class emulators are available for serial, mouse, mass storage, and composite devices. These operate with standard Windows(R) USB class drivers, thus providing easy connection to any Windows machine.

All smx USB products are written in ANSI C, and can be ported to any hardware platform. They are optimized for Micro Digital's SMX RTOS, but can be easily ported to other RTOSs. These USB products are modularized and feature small footprints and good performance.
