5.8 I7000_AnalogOut
z Description:
Send the analog output command to CB-7000.
z Syntax:
I7000_AnalogOut(WORD w7000[], float f7000[], char szSendTo7000[], char szReceiveFrom7000[])
z Input Parameter:
w7000: WORD Input/Output argument table
f7000: float Input/Output argument table
szSendTo7000: command string send to CB-7000
szReceiveFrom7000: result string read from CB-7000
z Return Value:
NoError: OK
others: Error code, refer to I7000.H
