7.1. Introduction.
7.1.1.
The following describes a very small application for isochronous transfers demonstration
from Host to Device, and from Device to Host. It is designed especially for Motorola
ColdFire5272 USB Protocol Stack audio sample (see [3]) firmware. The Client
application demonstrates how the ColdFire firmware Driver handles control and
isochronous transfers. The MCF5272 USB Driver and audio sample Client firmware
components work together on the Device, to perform PCM samples loop-back using
simultaneous isochronous transfers through isochronous IN/OUT endpoints. The
application is capable of demonstrating the Stand-Alone and uClinux versions of the
Device-side firmware component, due to USB protocol transparency. Additionally the
application demonstrates a working MOTUSB Driver and dynamic link library software
components on the Host side.
