GPIO API and Example Applications
This section will show you how to develop applications under a WinCE
environment by giving an introduction to GPIO API and example
applications.
The APIs involved when developing applications based on the SBC8140 are
using the Windows Embedded CE 6.0 API and have been expanded only in
GPIO interface definition. The applications that control pin status can be
found under X:\WINCE600\app\GPIOAppDemo (where X is the label of
your PC’s DVD drive).
Please view the relevant documents of MSDN Windows Embedded CE 6.0
API to learn about Windows Embedded CE 6.0 standard API definition.
Note:
The interfaces derived from some drivers can only be used by other drivers,
applications do not have access to these interfaces.
The GPIO devices name is L"GIO1:" with expanded DeviceIoControl
interface definition; the following table lists the corresponding IOCTL code;
