pulseShape short: shape of pulses:

0 (negative-going for 1 clock period)

1 (negative-going square pulses)

trainClock short: clock source for the train rate generator.

One of the following pre-defined constants may

be used:

CLK_1MHZ = 2 (fixed 1 MHz clock)

CLK_100KHZ = 3 (fixed 100 kHz clock)

CLK_10KHZ = 4 (fixed 10 kHz clock)

CLK_1KHZ = 5 (fixed 1 kHz clock)

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)

trainFreq double: desired train frequency in Hz. The

actual frequency will be rounded to an integral

division of the train clock frequency.

Returns short: Handle to the restricted periodic pulse train generator (>= 0) ). Use

this handle to call the TCfreeRestrictedPulseTrain function when

finished, in order to free up the counter/timers for re-use.
