AioSetCntInputSignal


Function

Sets the type of counter input signal.

Format

Ret = AioSetCntInputSignal ( Id , CntChannel , CntInputSignal )

Parameters

Id [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the ID retrieved from AioInit.

CntChannel [ C, C++ : short ] [ Python : ctypes.c_short ]
Sets the channel of counter.

CntInputSignal [ C, C++ : short ] [ Python : ctypes.c_short ]
Sets the clock type from the following range.
The value that can be set is different according to device.

0

External clock (Fixed)

Return values

Ret [ C, C++ : long ] [ Python : ctypes.c_long ]
