58 PanelView Plus CE-Specific Extensions to the WinCE API
Requirements:
Hardware Monitor The PanelView Plus CE platform provides a hardware monitor driver
that can be called by applications to monitor the status of various
board parameters. In addition, the hardware monitor provides
functions to Reboot the board and to query the last reboot reason.
Hardware Monitor Parameters
These platform parameters are monitored by the HardwareMonitor
driver.
• 3-Volt battery voltage
• CPU Temperature
• Display Temperature
Note that the monitored parameters are of fundamentally different
types. Therefore the units of the parameters will vary according to the
parameter being monitored. For example, when an application sets
the warning levels for the 3V-battery voltage, the units of the levels
specified in HardwareMonitor API functions will be Volts. However,
when an application sets display temperature warning levels, the
application must specify temperature in degrees Celsius. Parameter
units are shown Table and described in more detail below for each
API function.
