Well maybe you should try replacing the HC11 for a start.. These things tend to spoil easily and for no apparent reason.... :( (or is it just bad luck?) That's funny, you shorted out something and it still can download? Maybe you should also change (...) (26 years ago, 22-Oct-98, to lugnet.robotics.handyboard)

Hi All, While I was building my sumo robot I managed to short a wire in my HB. I put a wire that was connected to a multimeter and also connected to another part of the robot, into a digital sensor input, sparks came out and it smelt like burnt (...)

It sounds like you've got the switch between +5V and GND. What pins exactly are you connecting to? The sensor connections Are like this: _ _ _ G + I N 5 N D V P You dont need a resistor to use a microswitch. The HB inputs have pull-up resistors, so (...)

There is the Micro Kernel from Jean J. Labrosse. It's a free kernel readily available, also for the 68hc11. I have his book but haven't implemented the full kernel yet, only parts of it. Its well written and cheap. Look at: (URL) jaron paludanus (...) (26 years ago, 21-Oct-98, to lugnet.robotics.handyboard)

I just got my HB and am trying to test the sensor input, the docs say to hook up the microswitch between signal and ground, when I do this and close the switch my hb resets (because I just shorted it out...).

To me is seems, that multitasking futures of IC is very insufficient. Is exist any small, inexpensive RTOS (real time operation system), that is tested for HB? I'm hear that RTXC, RTEK or MCX11 may be that RTOS. Is anybody tested some RTOS with HB? (...) (26 years ago, 21-Oct-98, to lugnet.robotics.handyboard)
