AioSetDemoDiByte

Function

This is a function that sets the digital input of the demo device in port.

Format

Ret = AioSetDemoDiByte ( Id , DiPortNum , DiPort , DiData )

Parameters

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

DiPortNum [ C, C++ : short ] [ Python : ctypes.c_short ]
Specifies the number of elements in the port number array.

DiPort [ C, C++ : short * ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the array that stored the port number.

DiData [ C, C++ : short * ] [ Python : ctypes.POINTER(ctypes.c_short) ]
Specifies the address of the array that stored the data.

0	OFF
1	ON

Return values

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

Return values	Content
0	Normality completion
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.
18123	Pointer to DiPort, DiData is NULL
28120	The value of DiPortNum is outside the designated range of the device being used
28121	The value of DiPort is outside the designated range of the device being used
28122	The value of DiData is outside the designated range of the device being used
28123	A driver inner error occurred

Remarks

This is a function dedicated to the demo device.

One port has 8bit. And all initial values are 0 (OFF).

Please call AioInputDiByte function when you want to confirm the current Digital Input value.

Example

Sets the digital input data FH (bit0, bit1, bit2, bit3 ON) for port 0 to port 7.

C, C++	long Ret; short DiByte[8]; short DiData[8]; short i; for( i = 0 ; i < 8 ; i++ ){ DiByte[i] = i; DiData[i] = 0xF; } Ret = AioSetDemoDiByte ( Id , 8 , &DiByte[0] , &DiData[0] );
Python	Ret = ctypes.c_long() DiByteType = ctypes.c_short * 8 DiByte = DiByteType() DiDataType = ctypes.c_short * 8 DiData = DiDataType() for i in range(8): DiByte[i] = i DiData[i] = 0xF Ret.value = caio.AioSetDemoDiByte ( Id , 8 , DiByte , DiData )
