Digin_Edge
Digin_Edge
returns whether a positive or negative edge has occurred on
digital inputs.
Syntax
#Include
ADwinGoldII.inc / GoldIITiCo.inc
ret_val
=
Digin_Edge
(
edge
)
Parameters
Notes
A set bit in
ret_val
means, that a selected edge has been occurred at
least once at the digital input since the previous query. Bit for output
channels always return zero.
A query with
Digin_Edge
resets all bits to zero.

ret_val
Bit pattern where each bits represent an edge
occurred at an input. The mapping of bits to inputs
is shown below.
Bit = 1: An edge has occurred.
Bit = 0: No edge occurred.
