DioSetDemoBit

Function

Sets 1 bit of data to the input bit of the demo device.

Format

Ret = DioSetDemoBit ( Id , BitNo , Data )

Parameters

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

BitNo [ C: short ] [ Python: ctypes.c_short ]
Specifies the logical input bit number.
The logical input bit number is a number, which is assigned from the first input bit of the device as 0 to the last one serially.

Data [ C: unsigned char ] [ Python: ctypes.c_ubyte ]
Specifies the input data as 0 or 1.

Return Value

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

DIO_ERR_SUCCESS	0	Normal completed.
DIO_ERR_DLL_INVALID_ID	10001	Invalid ID is specified.
DIO_ERR_DLL_CALL_DRIVER	10002	Driver cannot be called (failed in ioctl).
DIO_ERR_SYS_NOT_SUPPORTED	20001	This function cannot be used for this device.
DIO_ERR_SYS_BIT_NO	20102	Bit number is outside of the available range.
DIO_ERR_SYS_BIT_DATA	20104	Bit data is neither 0 nor 1.

Initial Value

This is dedicated function for demo device.

The initial value of the input data is 0, after the device was reset.

Please call DioInpBit function when you want to confirm Digital Input Value.

Remarks

Sets 1 bit of data to the input bit. Specifies the input data as 0 or 1.

Example

Sets the input data 1 to bit 0.

C	Ret = DioSetDemoBit ( Id , 0 , 1 );
Python	Ret = cdio.DioSetDemoBit ( Id , 0 , 1 )
