Has no effect on boards without gate connection registers.
i = TCchangeRestrictedPulseTrainGate (h, hRPT, trainGate)
where h short: board handle as issued by the
registerBoardEx function.
hRPT short: restricted periodic pulse train generator
handle, as issued by the
TCsetRestrictedPulseTrain function.
trainGate short: gate input source for the train rate
generator (if the board has gate connection
registers). One of the following pre-defined
constants may be used:
GAT_VCC = 0 (gate on/high)
GAT_GND = 1 (gate off/low)
GAT_EXT = 2 (gate from external
input)
GAT_OUTN_2 = 3 (gate from inverted
output of a timer
channel offset by -2
from train channel)
Returns short: OK

6.4.8.16 Change Restricted Periodic Pulse Train’s Frequency — TCchangeRestrictedPulseTrainFreq
Changes the frequency of trains for the restricted periodic pulse train generator (as set up by
TCsetRestrictedPulseTrain) to the specified value.
SUPPORTED IN VERSION 4.32 ONWARDS.
i = TCchangeRestrictedPulseTrainFreq (h, hRPT, trainFreq)
where h short: board handle as issued by the
registerBoardEx function.
hRPT short: restricted periodic pulse train generator
handle, as issued by the
TCsetRestrictedPulseTrain function.
trainFreq double: desired train frequency in Hz. The
actual frequency will be rounded to an integral
