    sleep timer interval

    prajakta.zagade

      Hello all,

         

      I am  using CY8c3244PVI-133 controller for one of my project.

         

      I want to generate a signal of 40msec on one of the port pin.

         

      I designed in such a way that it will generate a signal and again go back to sleep. and wakeup generate a pulse and again back to sleep.

         

      i.e. sleep->wakeup->high pulse->sleep->wakeup->low pulse->sleep and so on

         

      I am using sleeptimer and in the isr of sleeptimer I am toggling one port pin.

         

      If I set sleeptimer interval = 4sec, port pin is high for 2sec and low for 2sec

         

      If I set sleep timer interval = 2sec then port pin is high for 1sec and low for 1sec

         

      oscillator for sleep timer is ILO i.e 1KHZ

         

      Please guide.

         

      Thank you all
