swerve drive with arduino mega 2560

[techhelpbb]

If you want trig functions you don't actually need full floating point support: use a look-up table.

BTW there are trig look-ups masked into the Parallex Propeller just for this reason,

all oof the answers are confusing me, the calculations i can probably figure out on my own, and the whole thing is completely set up except for the code, which is what i need help with. i put the issue in the description of the problem im having. butvtganks anywayb also, i cant switch the setup of what im using significantly, like using somethingbother than a swerve drive, arduino, ot talons, but i can out thungs on it. also, sorry for the spelling mistakes, im using a touch screen computer and its hard to type correctly

i just realized I didn't put the issue in for lack of time, here is what is going wrong:
i clicked burn bootlegger after doing all previous steps correctly and this came up-

Arduino: 1.6.9 (Windows 8.1), Board: "Arduino/Genuino Mega or Mega 2560, ATmega2560 (Mega 2560)"

Problem uploading to board. See http://www.arduino.cc/en/Guide/Troubleshooting#upload for suggestions.

I'm not sure why you would have to do "burn bootloader." Arduino boards come hot out of the gate ready to go.

Under "tools->board" make sure you have the correct Arduino hardware selected. Then check that you have the correct "com" port selected.

Then press the upload arrow and you should be running code. Test this with the supplied examples before trying to upload your own custom code.
