    one shot timer

    guenter.dengler

      Hello,

         

      is the one shot timer function (CyU3PTimerCreate with RescheduleTicks=0) already implemented?

         

      I can not get it working.

         

      Best regards

          Are you seeing any error being returned or does the API succeed but without the expected output?

             

          Please post the code that you're using as well I would like to look at the parameters you're using.

             

          Regards,

            Hello,

               

            i tried it like follows:

               

            CyU3PTimer pTimer1;   // global

               

            Initialisation:

               

                CyU3PReturnStatus_t status = CY_U3P_SUCCESS;
                uint32_t nExpirationInput=0;
                uint32_t nInitialTicks = 10;
                uint32_t nRescheduleTicks = 0;       // If set to zero, the timer will be a one-shot timer
                uint32_t nTimerOption = CYU3P_NO_ACTIVATE;
                status = CyU3PTimerCreate(&pTimer1,TimerFunc1,nExpirationInput,nInitialTicks,nRescheduleTicks,nTimerOption);
                if (status != CY_U3P_SUCCESS){
                        CyU3PDebugPrint (4, "CyU3PTimerCreate Failed, Error Code = %x\r\n",status);
                    }
             

               

            Start of one shot timer:

               

                CyU3PReturnStatus_t status = CY_U3P_SUCCESS;

               

                status = CyU3PTimerStart(&pTimer1);    //re-start one-shot timer
                if (status != CY_U3P_SUCCESS)
                    CyU3PDebugPrint (4, "CyU3PTimerStart Failed, Error Code = %x\r\n",status);
             

               

                CyU3PTimerStart gives me the error : CY_U3P_ERROR_ACTIVATE_FAILED

               

             

               

            Best regards
