Sets the timing of external clock input.
Ret = AioSetAiClockEdge ( Id , AiClockEdge )
Id
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Specifies the ID retrieved from AioInit function.
AiClockEdge
[ VB.NET : Short ] [ C, C++ : short ] [ C# : short ] [ Python : ctypes.c_short
]
Sets the timing of external input from the following range.
0 |
External input falling edge |
1 |
External input rising edge |
Ret [ VB.NET : Integer ] [ C, C++ : long ] [ C# : int ] [ Python : ctypes.c_long ]

External input falling edge is used for all devices. *
If the external clock is set by AioSetAiClockType
function, it is possible to set external trigger falling edge or rising
edge.
When internal clock is being used, the setting by this function is invalid.
This function cannot be used on devices without
the analog input function.
If the device is in operation, the function cannot be performed.
DEMO DEVICE do not support external clock function.

For these devices, whether AioSetAiClockEdge function can be used or not
depends on manufacturer's serial version.
This function returns 20001 error as unsupported version of hardware is
being used.
Uses the external input rising edge as the clock.
