Parameter
These bit operations are useful in Visual Basic
applications to access individual bits within an
integer. The BitSetTo function either sets or
clears the specified bit based on the value of
bBitValue. Any non-zero value for Data turns on
the bit. The BitSet and BitClr functions set and
clear the specified bit. Bit numbers start at zero
for the least significant bit (LSB).
The zero at the end of the parameter name
“BitNumber0” serves as a reminder of this fact
for anyone looking through the function defini-
tions in either the .BAS file or the .H header
files. PamuxUtilBitTest returns true if bit number
BitNumber0 in Data is set.
Gets an analog board’s status and returns
an equivalent error. Analog read functions
also return the same result after perform-
ing their read. An analog configure func-
tion can be used to clear the “power-up”
error. The “old data” error is cleared by
the B6 processor as it updates inputs.
This function could be used to wait for
fresh input data.
