How do you know when you are "using too much resources" when installing
programs into the system interrupt?
Is there a limit to how long the system interrupt routine can last?
What happens if all the instructions I place in there causes the whole
interrupt to last more that 1 msec?

| (...) Yes, 1 mSec. (...) Time slows down (the tick counter is no longer accurate), your motors get variations in their PWM signal, and you risk losing syncronization with any servos you have out holding position. (27 years ago, 19-Nov-97, to lugnet.robotics.handyboard)
