2. ibApi_IO_SetADCConfig()
ibApi_FUNC ibApi_IO_SetADCConfig (
ibApi_APIHANDLE api_hdl,
ibApi_DEVICEID device_id,
ibApi_UINT8 channel_index,
ibApi_BOOL enabled
);
This sets whether the specified ADC channel is enabled or disabled. The channel must be
enabled before calling ibApi_IO_ReadADC().
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.
enabled: (input) ibApi_TRUE to enable the channel.
Return Value:
An ibApi_RESULT_SUCCESS if successful, or an error code (<0) if not.
3. ibApi_IO_GetADCConfig()
ibApi_FUNC ibApi_IO_GetADCConfig (
ibApi_APIHANDLE api_hdl,
ibApi_DEVICEID device_id,
ibApi_UINT8 channel_index
);
This queries whether the specified ADCchannel is enabled or disabled.
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.
Return Value:
An ibApi_TRUE if enabled, ibApi_FALSE if disabled, or an error code (<0) if not.
4. ibApi_IO_ReadADC()
ibApi_FUNC ibApi_IO_ReadADC (
ibApi_APIHANDLE api_hdl,
ibApi_DEVICEID device_id,
ibApi_UINT8 channel_index,
ibApi_FLOAT * adc_value
);
