(...) I'm unfamiliar with the workings of IC, but if your interrupt service routine is sufficiently short, and you don't reset the interrupt mask to enable recursive interrupts, you shouldn't notice the difference. You asked if there was a more (...) (27 years ago, 9-Jun-97, to lugnet.robotics.handyboard)

I'm in the middle of planning/writing a small program that will read a digital input to determine it's frequency & pulse width. I thought it'd be nice to have this part of the program (in assembly) running off the system interrupt so that these (...) (27 years ago, 9-Jun-97, to lugnet.robotics.handyboard)

Maze-running competitions are one of the earliest ways used to test mobile robots. They force developers to build mechanical mice that quickly learn the most effective path to a goal and reach it in the shortest time. The mazes range from tabletop (...)
