int WINAPI Read_Resolution (int Card, int Channel)

DESCRIPTION

Reads the given channel, and returns the current resolution.
If bits are: 16 Resolution is 16
If bits are: 14 Resolution is 14
If bits are: 12 Resolution is 12
If bits are: 10 Resolution is 10

INPUT DATA

Card = an integer between 0 and 7 for the card of interest. The card number is set in the
MOTION FEEDBACK BOARD MANAGER.

Channel = an integer between 0 and 5 for the channel of interest.

RETURNED DATA

This routine returns an integer that represents the current resolution of a channel as either
10,12,14, or 16 bits. If a 9 is returned than there was an error with the initialization of the
card.

EXAMPLE CODE

Code Result/Returned

Data

int Resolution;

Resolution = Read_Resolution(4,3);

Returns the current

resolution (as an integer)

for card #4, channel 3.
