    complex gpio

    user_136061072

      Hello,

         

      is it possible to create a defined pulse (length,initial value) at a Complex-GPIO-Output pin?

         

      How can this be done ( timermode,period)?

         

      I use beta2 sdk.

         

      Best regards

          What is the type of functionality you're trying to achieve? Please share more details on it.

            Hello,

               

            i try to explain it more in detail.

               

            I have one pin (pinA) configured as Interrupt-Input.

               

            when i detect a falling edge, i want to create a pulse on another Pin (PinB).

               

            pinA :  ---------------|_________|------------

               

            pinB:  _________|--|______________

               

            The length of the pulse should be configurable (< 1 msec).

               

            It is not possible to do this with a timer and simple gpio(which i have tried),

               

            so maybe it is possible with a cpmplex gpio.

               

             

               

            Best regards

              Hi,

                 

              It does seem possible at first look. Can you please create a tech support case (MyAccount->MyCases) for this so that one of our engineers can look at the kind of flexibility you're looking at and the method that'll be needed to implement it.

                 

              Regards,
