7. ibApi_IO_GetDIOConfig()
ibApi_FUNC ibApi_IO_SetDIOConfig(
ibApi_APIHANDLE api_hdl,
ibApi_DEVICEID device_id,
ibApi_UINT8 channel_index,
);
This queries whether the specified DIO channel is configured for input or output, which
governs the interpretation of ibApi_IO_ReadDIO().
* and ibApi_IO_WriteDIO()
Parameters:
api_hdl: (input) API handle returned from ibApi_Open().
device_id: (input) ID of the device to be accessed.
channel_index: (input) Channel index to access.
io_mode: (input) the new input/output mode
Return Value:
An ibApi_IOMODE value if successful, or an error code (<0) if not.
8. ibApi_IO_WriteDIO()
ibApi_FUNC ibApi_IO_WriteDIO (
ibApi_APIHANDLE api_hdl,
ibApi_DEVICEID device_id,
ibApi_UINT8 channel_index,
ibApi_UINT8 dio_value
);
This sets the value of the specified DIO channel. Note that an error will result if the channel is
not configured for output.
Note: In some product models, the DIO pins are shared with the serial data
interface and will be disabled when it is active.
Parameters:
api_hdl: (input) API handle returned from ibApi_Open().
device_id: (input) ID of the device to be accessed.
channel_index: (input) Channel index to access.
dio_value: (input) New output level (0 or 1).
Return Value:
An ibApi_RESULT_SUCCESS if successful, or an error code (<0) if not.
