SOFTWARE DESIGN
The USB demonstration program consists of the following files (
Table 5.
and
Table 6.
).
Table 5. List of Header Files
Table 6. List of C Source Files
When developing USB code the for μPSD32xx family, there are software design issues or considerations
that must be taken into account. These are discussed in this section.
USB Communication Flow
The USB provides a communication service between software on the host and its USB function. Functions
can have different communication flow requirements for different client-to-function interactions. The USB
provides better overall bus utilization by allowing the separation of the different communication flows to a
USB function. Each communication flow makes use of some bus access to accomplish communication
between client and function. Each communication flow is terminated at an endpoint on a device. Device
endpoints are used to identify aspects of each communication flow.
Figure 3.
shows a more detailed view of communication flow between the device and the host. It supports
the logical device and function layer communication flows. These actual communications flows cross sev-
eral interface boundaries.
