Sonic Depth Meter code & Math problems 12F683

I 'd use what Henrik has posted and maybe with a smaller multiplier, say 3000. Keep your ten average pile. Then Henrik's lines will give you directly the result for your digital pot.

'Main Program  ****************************

'get avg depth
    pause 1000
    for x = 1 to 10
        pulsin gpio.4,1,inputpulse
        dist= dist + inputpulse
        pause 100
    next x
    
    newtapsetting = (dist ** 3060) - 42       'try also a number smaller, 3000
    IF newtapsetting > 127 THEN newtapsetting = 127

serout gpio.0,t9600,[12,"avg :", #avgdist,13]
serout gpio.0,t9600,["tap :", #newtapsetting]

pause 500

end
