    hi every one[:D].
    i am using dspic30f4011 to give totally 6 pwm pulses(two at a time) depending on the inputs in my motor(BLDC) control operation.
    After dumping the program i tested. I used potentiometer(pot) to vary the pulse width.
    at pot zero postion no pulse is coming but when i increased pot value all the six pwm pulses are coming at a time.
    i need only two pulses at a time.
    please tell me the reason why it is happening. please give me suggestions how to avoid this condition.
    thank you..

    You programmed it wrong.
    Don't program it wrong.



    Without knowing anything more, there isn't much help to offer. If you'd like solutions, provide a schematic, code, and what you've tried to debug it.

    Unbelevibale! It is "URGENT" yet the OP posts no information that might allow others to help. ust not have been so "urgent".


    BTW Urgent usually means: I have a project due tomrrow for my class. I have not been playing with my game boy and not paying attention in class. I have no idea what I am doing. Please do my project for me.

    You already got a reply. How do you expect anyone to help you if you don't provide the information that was requested (twice now)?

    Why should anyone help you if you are not going to put any effort into your own problem?

    Well I guess it was too difficult to post a schematic and troubleshooting findings.
