6.4.7.8 Prepare a 32-Bit Event Counter — TCsetEventCounter
Sets up a 32-bit event counter, which uses 2 timer/counters to count events on the clock input
of the specified timer/counter channel.
An 'event' is a rising edge followed by a falling edge on the clock input.
If an internal clock source is used to provide the events, this is similar to the stopwatch
function.
SUPPORTED IN VERSION 4.42 ONWARDS.
See section 3.1.10 for more information on the 32-bit event counter application.
i = TCsetEventCounter (h, chip, chan, clock)
where h short: board handle as issued by the
registerBoardEx function.
chip short: address offset of the timer/counter chip.
One of the following pre-defined constants may
be used:
X1 = 0
X2 = 4
Y1 = 8
Y2 = 12
