XPS Unified Programmer’s Manual
7.2.1.57 GPIOAnalogGainGet
Name
GPIOAnalogGainGet – Gets the gain for one or several analog inputs (ADC).
Input tests
- Refer to section 7.1: “Input Tests Common to all XPS Functions”.
- Checks board: (-8)
- GPIO name (ADC): (-8)
- Hardware compatibility or XPS initialization in progress: (-22)
Description
Gets the gain value for one or several analog inputs. Please refer to Appendix B.5
Analog I/O of the XPS Motion Tutorial for further information about ADC gain.
The gain value must be 1, 2, 4 or 8.
The maximum number of INT boards that can be plugged inside the XPS controller is 2,
increasing the number of analog inputs (ADC) from 4 to 8.
Prototype
int GPIOAnalogGainGet(
int SocketID,
int NbElements,
char * GPIONameList,
double * AnalogGainValueArray
)
Input parameters
SocketID int Socket identifier gets by the
“TCP_ConnectToServer” function.
NbElements int Number of analog GPIO to read.
GPIONameList char * List of analog input names – separator is
comma.
Output parameters
AnalogGainValueArray int * Value of analog input gain.
Return (In addition to the results of “Input Tests Common to all XPS
Functions”)
• 0: No error.
• -8: Wrong object type for this command.
• -22: Not allowed action.
