Dead zone for RC control

I'm using the arcade drive controls through Easy C, but the current controller the drivers want to use doesn't center itself very well, so I need to know if there is anyway to put a dead zone into the code. Thanks for the help.

I figured out a really easy way to do it. Turns out I just didn't think it through. I made a simple If-Else statement. If the joystick values are between then set pwms as 127 else tank drive. Worked well enough.

Re: Dead zone for RC control

A very readable way to do it is to make an inline function like this:

Code:

#define STOP 127

#define DEAD_ZONE 15 // or any other number, fool around with this to make it work as you want it to

#define IN_DEAD_ZONE(x) (x <= DEAD_ZONE + STOP && x>= STOP - DEAD_ZONE)

This would work with something like this:

Code:

if (IN_DEAD_ZONE(p1_y))

p1_y = STOP;
