StartDIOPulse

Start a digital output pulse for the main board or a DIO option card.

int StartDIOPulse(int bd, int out, uint8 cond, int count, float pulseWidth, float dutyCycle);

int StartDIOPulse(int bd, int out, float dutyCycle);

Parameters

• bd - number of digital output card (main board output is not supported for pulse)
• output - output number (outputs 1 - 4) only are supported
• cond - DIO_PULSE_HIGH = start with output on, DIO_PULSE_LOW = start with output off
• count - count of pulses to output, 0 = continuous until StopDIOPulse
• pulseWidth = size of the cycle in seconds
• dutyCycle = duty cycle .5 = 50 percent duty cycle

Return Value

• Returns the result - OK success

Remarks

Requires main board version 1.19 and DIO card firmware version 0.05 or greater. The main board or option card must already be opened by calling OpenMnBd first. The call does a wait for acknowledgement. If the application is using main board communication events these events may be called during the wait for acknowledgement.

Examples

if(StartDIOPulse(1, 1, DIO_PULSE_HIGH, 10, 2.0, 0.5) == OK)
    DisplayText(0, 0, "10 pulses 1 sec on 1 sec off");

if(StartDIOPulse(1, 4, 0.7) == OK)
    DisplayText(0, 0, "Card 1 Output 4 70 pct");
