Is someone can tell me if there's a difference between these two way of mesuring a pulse width.
First simply by using PULSIN
PULSIN PIN_IN,0,PULSE_WIDTH
Or by using WHILE WEND like this
WHILE PIN_IN = 0
PULSE_WIDTH = PULSE_WIDTH + 1
WEND
I know PULSIN increment by 10us step using a 4MHz Xtall. Do the While wend way can be more accurate ? Is there a way to know how many cycles required by this code ?
Thank you
