AioSetAoClockType

Function

Sets the clock type.

Format

Ret = AioSetAoClockType ( Id , AoClockType )

Parameters

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

AoClockType [ C, C++ : short ] [ Python : ctypes.c_short ]
Sets the clock type from the following range.
The available value differs by the device.

0	Internal clock
1	External clock
10	Event controller output

Return value

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

Return values	Content
0	Normality completion
7	Execute AioResetDevice function because the device has recovered from standby mode
10001	Invalid Id was specified Use the Id retrieved from AioInit to specify the Id in this function.
10002	AIO driver can't be called At first, perform AioInit function.
13180	The value of AoClockType is outside the designated range of the function
20001	This function can't be used by this device
20002	Can not use while by another device works To use this function, analog output operation must be stopped.
20003	Can not use because another process is using the device When another process is using the device, all functions except for those that support multi-process can not be performed.
23180	The value of AoClockType is outside the designated range of the device being used

Initial value

Internal clock is used for all devices.

Remarks

If the Internal clock and system time are used as the clock, please use AioSetAoSamplingClock function to set the internal clock.
If the event controller output is used as the clock, please use AioSetEcuSignal function to set the connection of the event controller.
If you only perform this function, the connection of the event controller isn't changed.

This function cannot be used on devices without the analog output function.
If the device is in operation, the function cannot be performed.

Example

Uses the internal clock as the clock type.

C, C++	long Ret; Ret = AioSetAoClockType ( Id , 0 );
Python	Ret = ctypes.c_long() Ret.value = caio.AioSetAoClockType ( Id , 0 )
