eCosPro Jungo USBware™ USB Stack Middleware

Does your eCos based embedded device require USB host, device or OTG support? The USBware stacks are optional middleware components for eCosPro that enable USB functionality to be incorporated into your design with the minimum of effort. The stacks are high quality, mature, and featureful implementations of the universal serial bus standard protocols and classes.

USBware stack architectural block diagram

The USBware stacks consist of three logical layers communicating through two interfaces. The stacks upper portions are the Class/Device Driver layers, representing the various class/function drivers that can be incorporated into the stack. The middle Core layers are responsible for providing the common core USB stack functionality - host, OTG, or device. The lowest Controller Driver layers are responsible for abstracting the physical controller hardware.

The eCos specific implementation of the USB OS Wrappers integrates the stack into eCos, and along with full gnu gcc toolset compatibility, minimizes the effort required to add USB functionality into your device.
