4.7.5 WDT Modules

SPC is targeted to be the embedded device for web-enabled and data-acquisition systems. It is built-in with a useful dynamic link library, WATCHDOG.DLL, which has been designed to help AP developer easily implement his requirements of handling the system resources such as Watchdog timer and LCD brightness control etc. Programmers who are familiar with WIN32 API programming would feel very easy to use this DLL to create his functions. The DLL make its device services look as a file whose name is "WDT1:". The programmer could use this file name in "CreateFile()" to open it and get the file handler. Then the following controls of user required device services would be achieved by way of the file handler in one function call of "DeviceIOControl()". At most 5 applications can access watchdog timer simultaneously. The DeviceIOControl function is following:
