Hi,

I am building a NXT remote control program but atempt a problem.

I am now success to reading sensors even ultrasonic(sonar) sensor.

But I want to set the sonar to imperial(inch) unit or metric(Centimeter)
unit.

Or, want to know how to reading from the sonar in inch or cm unit.

Of course, I am reffered the Direct command documentation, Ultrasonic I2C
protocol document...and so on

but it is so difficulty to understand and use it's contents.

anyway, I try it, but failure.

I also search for google and some famous LEGO NXT web site, but can't find
exactly answer.

They say with some lib or tool like NXC, java, C++ lib... etc. but I don't
have them.

What I want to know is the data give the sonar in LSWRITE command or in the
return package.

aaaaaahh... I am tired... please let me know...

(...) The sensor itself returns only cm values. To use inches just multiply the result by 100 and divide by 254 (1 inch = 2.54 cm, but since we are dealing with integers we use 1/2.54 = 100/254) Philo (16 years ago, 7-Mar-09, to lugnet.robotics)
