(0): from low to high

> detect the din event
DIN_EVENT_HIGH_TO_LOW or
DIN_EVENT_LOW_TO_HIGH with
duration. The value of “duration” must be a
multiple of 20 milliseconds. The range of
“duration” is 0, or 40 <= duration <= 3600000
milliseconds. The error of the measurement is
24 ms. For example, if the DIN duration is
200 ms, this event will be generated when the
DIN pin stays in the same state for a time
between 176 ms and 200 ms.
Output: none.
Return: reference the error code.
int get_din_event(int diport, int *mode, long int *duration)
Description: To retrieve the DIN event configuration, including mode
(DIN_EVENT_HIGH_TO_LOW or DIN_EVENT_LOW_TO_HIGH), and the value of
“duration.”
Input: int diport - which DIN port you want to retrieve.
- The port whose din event setting we wish to retrieve
int *mode - save which event is set.
unsigned long *duration - the duration of the DIN port is kept in high or low state.
- return to the current duration value of diport
Output: mode DIN_EVENT_HIGH_TO_LOW
(1): from high to low
DIN_EVENT_LOW_TO_HIGH(0): from low to high
DIN_EVENT_CLEAR(-1): clear this event
duration The value of duration should be 0 or 40 <= duration
<= 3600000 milliseconds.
Return: reference the error code.
Special Note
Do not forget to link to the library libmoxalib.a for DI/DO programming, and also include the
header file moxadevice.h. The DI/DO library only can be used by one program at a time.
