Today SCIOPTA Systems AG is announcing the immediate availability of the USB Host Stack for embedded systems running under the SCIOPTA real-time operating system.
The SCIOPTA USB host stack is specifically designed for embedded systems. It contains the core protocol stack, the required host controller device drivers, a low-level communication API and high-level class drivers.
SCIOPTA USB host stack provides high-level class drivers for keyboards, mice, touch screens, printers, mass storage devices (disks, memory sticks, floppies, digital cameras, CD-ROMs, DVDs, etc.), and ASIX USB-Ethernet bridge devices.
SCIOPTA USB Hoast stack is royalty free and available for SCIOPTA supported CPUs which are equiped with USB host controllers.
All major USB 1.1 and 2.0 host controller such as UHCI, OHCI and EHCI types are supported. These controller types are always supported, regardless of their respective vendor or model.
All USB data transfer types/protocols (bulk, interrupt and isochronous) can be used to support both high throughput and real-time oriented devices..
Low, full, and high speed data transfer can be used. Up to 12 Mb/s on USB 1.1 and 480 Mb/s on USB 2.0 buses are supported.
The SCIOPTA USB host stack automatically detects devices and/or hubs being added and removed from the bus and can call application supplied callbacks for each event of such a type. The application can then decide whether to enable and operate the device or not. The host stack supplies functions to query a device’s name, vendor, class, descriptors, interfaces, endpoints, etc.
Host Stack Class Drivers
A hub class driver is integrated in the core USB protocol stack. Class drivers allow applications to use a device without being concerned about details, such as the transfer type and speed to use, etc.
The mass storage device class driver requires a file system such as SCIOPTA SFATFS.
The USB-Ethernet bridge drivers need the SCIOPTA IPS network stack.
