Two time variables are declared by the system, which can be used for counting time. As they
are updated by system clock, Don
’t write to them.
· extern volatile unsigned long sys_msec;
// in unit of 5 ms
· extern volatile unsigned long sys_sec;
// in unit of 1 second
These two variables are cleared to 0 upon power up.
Purpose： Shut down the system.
Syntax： void SysSuspend(void);
Example call： SysSuspend( );
Includes：
#include “SDK.h ”
Description： This function will shut down the system.When power on, the system will
resume or restart itself, depending on the system setting.
Returns： None.
Purpose： Set system delay time.
Syntax： void SysDelay(unsigned int ulTime);
Example call： SysDelay(6000);//delay 6 seconds.
Includes：
#include “SDK.h ”
Description： The function can delay system, its unit is millisecond.
Returns： None
Purpose： Set power on for resume or restart.
Syntax： void SetPowerOnState(int slState);
Example call： SetPowerOnState(0);//Power on for resume.
Includes：
#include “SDK.h ”
Description： This function can set power on status for resume or restart.
slState for 0:Set power on resume.
slState for 1:Set power on restart.
Returns： None
Purpose： Get power on status
Syntax： int GetPowerOnState(void);
Example call： if (GetPowerOnState())
_printf_color(COLOR_BLACK, “Power on for restart:”);
Includes：
#include “SDK.h ”
