Negative numbers? - Chief Delphi

I am a mentor now and I would be more proud of a National Chairmans Award which acknowledges my many years of service to the team and the community rather than a National Championship which acknowledges one great robot I helped build. - The Lucas [more]

Re: Negative numbers?

Also,

Code:

...
pwm01 = (-0.007874015748031496062992125984252) * (p1_y - 127) * (p1_y - 127) + 127;...

You will notice that

Code:

...
((p1_y - 127) * (p1_y - 127) + 127) / 127
...

will work much much better for your purposes. Since pwm01 is an unsigned char and the whole thing will be converted to a char later, it does not matter that you are doing integer division.

Sometimes you have to forget the lessons you're taught so well in Comp Sci.
