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.

17010

The value of Input is outside the designated range of the function

17011

Pointer to Source is NULL
Specify the address of variable to parameter.

20001

This function can't be used by this device

20002

Can not use while by another device works
To use this function, analog input and output, counter, timer operation must be stopped.

20003

Can not use because another process is using the device

Example

The Source signal connected with the analog output generating clock period is acquired.

C, C++

long Ret;
short Source;
Ret = AioGetEcuSignal ( Id , AIOECU_DEST_AO_CLK  , &Source );
 

Python

Ret = ctypes.c_long()
Source = ctypes.c_short()
Ret.value = caio.AioGetEcuSignal ( Id , caio.AIOECU_DEST_AO_CLK , ctypes.byref(Source) )
