5.14 _9111_AD_Read_Data_Repeat

@ Description

This function is used to read the AD conversion data n times continuously.

@ Syntax

C/C++ (DOS)

U16 _9111_AD_Read_Data_Repeat (U16 cardNo, I16 far *ADData, U16
n)

C/C++ (Windows 95)

U16 W_9111_AD_Read_Data_Repeat (U16 cardNo, I16 *ADData, U16
n)

Visual Basic (Windows 95)

W_9111_AD_Read_Data_Repeat (ByVal cardNo As Integer, ADData As
Integer, ByVal n As Integer) As Integer

@ Argument

cardNo:

The card number of PCI-9111 card initialized

ADData:

A/D converted value, please refer to section to learn the
relationship between the voltage and the value

n:

The number of times to read the AD conversion data

@ Return Code

ERR_NoError

5.15 _9111_AD_Set_Channel

@ Description

This function is used to set AD channel by means of writing data to the
multiplexer scan channel register. There are 16 single-ended A/D
channels in PCI-9111, therefore the channel number could be set
between 0 to 15. Under non-auto scan mode, the ADChannelNo stores
the channel number setting. Under auto-scan mode, the ADChannelNo
records the ending channel number.

@ Syntax

C/C++ (DOS)

U16 _9111_AD_Set_Channel (U16 cardNo, U16 ADChannelNo)

C/C++ (Windows 95)

U16 W_9111_AD_Set_Channel (U16 cardNo, U16
ADChannelNo)

Visual Basic (Windows 95)
