(...) Looks like a typo - try this in your handler instead: "bclr #6, @0xc9:8 \n\t" // Clear CMFA // (bit 6 of // TCSR) I haven't really checked the rest of the code for anything else, though. HTH, Mark (19 years ago, 19-May-05, to lugnet.robotics.rcx)

It's not a true realtime interrupt. Some events may be recognized immediately (e.g. a new "mailbox" message, and some may be recognized on a 100 millisecond background scan (e.g. a "click" event). The event monitoring code does not put the task into (...) (19 years ago, 19-May-05, to lugnet.robotics.rcx.robolab, lugnet.robotics.rcx)
