Pulse Width

The Pulse Width function will measure the width of an applied event from its rise to its fall (effectively one

half the period). The Base Address of the card is required as input to the function. The signal should be

applied to the CLOCK IN pin of the card. Software latency will be affected by the operating system and

will set a limit on the precision of the measurement.

unsigned pulse_width(unsigned BaseAddress);
