Dual rate!

Posted 02-26-2008 at 11:07 AM by cdog4w
I hooked up the dual rate pot and then setup the program to just spit out the byte values of the a2d over serial. I was expecting to read the value and have to do some math based on it to get the % of the wheel value to send out as the actual steering deflection.

When DR was on max, the DR pot reading exactly matched the wheel. When I turned it down, it matched the wheel, but was toned down. So no maths needed, i just read the DR pot! The cool thing is, I send the wheel, then the trigger, then the dual rate data (so it looks like a 3 axis joystick) so w/o software change in the pic, I can use either the dual rate or the raw wheel data with just a mapping change in ppjoy.

I also added a small deadband to the trigger and it seemed to help the odd throttle issues. I'm pretty happy with how it drives now.
