It is not suggested to use RC servo lib (including rcservo_SendPWMPulses()) and PWM lib (including pwm_SetPulseCount()) at the same time, because this may confuse the internal states of the two lib.

Currently, no PWM-mode API in RC servo lib of RoBoIO can stop PWM pulses directly. But you can try the following trick:

Code:: rcservo_SendPWMPulses(channel, period, duty, count); .... //trick to cancel PWM pulses of the last rcservo_SendPWMPulses(cannel, ...) call rcservo_SendPWMPulses(channel, period, duty, 1L); while(rcservo_IsPWMCompleted(channel) == false);

is there any way to cancel the pwm signal once started? in the following code I tried "break" while loop doesn't work

Code:: rcservo_SendPWMPulses(channel, period, duty, count); while(rcservo_IsPWMCompleted(channel) == false){ break; }
