Page 55

ADChannelNo: selected channel number or the ending channel number to perform A/D conversion.

@Return Code

ERR_NoError

5.16_9111_AD_Get_Channel

@ Description

This function reads from the multiplexer scan channel register to get the AD channel number and the value is stored in ADChannelNo. Under non-auto scan mode, the bit 0 to 3 of ADChannelNo stores the channel number setting and the bit 4 to 7 of ADChannel is all ‘0”. Under auto-scan mode, the bit 0 to 3 of ADChannelNo records the ending channel number. The bit 4 to 7 of ADChannelNo is the selected channel.

@ Syntax

C/C++ (DOS)

U16 _9111_AD_Get_Channel (U16 cardNo, U16 *ADChannelNo )

C/C++ (Windows 95)

U16 W_9111_AD_Get_Channel (U16 cardNo, U16 *ADChannelNo)

Visual Basic (Windows 95)

W_9111_AD_Get_Channel (ByVal cardNo As Integer, ADChannelNo As Integer) As Integer

@ Argument

cardNo: The card number of PCI-9111 card initialized

ADChannelNo: channel number to perform A/D conversion

@Return Code

ERR_NoError
