PIC JAL IO Routine


by Vasile Surducan

I my application, count is a variable which is incremented or decremented from buttons, all problem with x84 is that you can't reached very small on pulses ( less than ms ) Probably with x84/20MHz is better.

I have use this to obtain a reference voltage after PWM is filtered.

Have anyone tried PWM with BETTER resolution than 8 bits with x84 ?

procedure pwm1 is
 pin_b7 = high
 for count loop
  asm nop
 end loop
 pin_b7 = low
 for ( 255 - count ) loop
 asm nop
 end loop
end procedure
