Easy function. This is a simplified version of AISample. Reads the voltage from 1 analog input. Calling this function turns/leaves the status LED on.
Execution time for this function is 20 milliseconds or less (typically 16 milliseconds in Windows).
Declaration:
long EAnalogIn ( long *idnum,
long demo,
long channel,
long gain,
long *overVoltage,
float *voltage )
Parameter Description:
Returns: LabJack errorcodes or 0 for no error.
Inputs:
-
*idnum – Local ID, serial number, or -1 for first found.
-
demo – Send 0 for normal operation, >0 for demo mode. Demo mode allows this function to be called without a LabJack.
-
channel – Channel command is 0-7 for single-ended, or 8-11 for differential.
-
gain – Gain command is 0=1, 1=2, …, 7=20. This amplification is only available for differential channels.
Outputs:
-
*idnum – Returns the local ID or -1 if no LabJack is found.
-
overVoltage – If >0, an overvoltage has been detected on one of the selected analog inputs.
-
voltage – Returns the voltage reading.
