   Hi, i have this code hos do i  calculate the frquency  and pulse width?   
      
   from machine import Pin   
   from rp2 import PIO, StateMachine, asm_pio   
   import time   
      
   led = Pin("LED", Pin.OUT, value=0)   
      
   @asm_pio(set_init=PIO.OUT_LOW)   
   def square():   
       # Cycles: 1 + 1 + 6 + 32 * (30 + 1) = 1000   
       irq(rel(0))   
       set(pins, 1)   
       set(x, 31)                  [5]   
       label("delay_high")   
       nop()                       [5]   
       jmp(x_dec, "delay_high")   
      
       # Cycles: 1 + 7 + 32 * (30 + 1) = 1000   
       set(pins, 0)   
       set(x, 31)                  [5]   
       label("delay_low")   
       nop()                       [1]   
       jmp(x_dec, "delay_low")   
      
   sm = StateMachine(0, square, freq=2000, set_base=Pin(0))   
      
   sm.irq(lambda p: led.toggle())   
      
   sm.active(1)
