Disadvantages to CAN? - Chief Delphi

I got something totally different from my FIRST experience. to me the spirit of FIRST is all about sharing. during the 6 week build period, you share yourself with the other people on your team. at the competition, you share your creation with everyone who watches your 'bot play the game. - George1902 [more]

The Jaguars closed loop modes (including current control) are performed at 1000hz. This is faster then possible when using PWM input (200hz), but slower then the h-bridge pulse rate (15,000hz).
