    PWM Square Wave of 38 kHz using Systick Timer

    user_350540870

      Hey All

         

      How is everyone doing? Hope all of you are enjoying the start of the year 2016 and getting more and more fascinated with PSoC like me.

         

      Today I have taken a task to Generate a 38kHz square wave with PSoC4 using a SysTick Timer. I have even designed a project related to that. My design, theoretically, will give square wave of around 38.4 kHz due to clock resolution limitation of PSoC4 that is 24 MHz.  I was checking the wave on CRO. (please find attached the CRO result image.) As it gave me some triangular wave, I decreased the frequency to 100 Hz and checked again with CRO. This time I got the perfect square wave.

         

      I kindly request you to please find attached my project designed for 38.4 kHz and give me a solution to get a perfect square wave. In addition, if anyone of you can give me a solution to get a perfect 38 kHz square wave than the current design of 38.4 kHz, I will be very much thankful.

         

       

         

      Thanks and Regards
