  Re: Basic Sensor Question
 
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 (...)

  RE: RTOS for HB?
 
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)
 
  Basic Sensor Question
 
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...). I tried putting a resistor (330 ohm) in (...) (26 years ago, 21-Oct-98, to lugnet.robotics.handyboard)

The results you get from a reflective IR sensor will vary quite a lot depending on surface color, roughness, angle of incidence, electrical noise, etc. My IR sensors were not good for much of anything besides encoders, (...)

  RTOS for HB?
 
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)
 
  Re: Questions about sensors
 
(...) One thing that was discussed before (I think on this mailing list?) that I thought was pretty cool was a small robot with a microphone (FM wireless mike perhaps?) and a photocell. It would stay in the shadows while trying to get close to (...) (26 years ago, 20-Oct-98, to lugnet.robotics.handyboard)
 
  Questions about sensors
 
Hi all, I'm having fun with my HB! For a software guy like me a 8 bit processor at 2 Mhz with 32K of RAM is a little small but it's so easy to add sensors to it it's just plain fun! But I'm an hardware newbie and I need more info on the sensors I (...) (26 years ago, 20-Oct-98, to lugnet.robotics.handyboard)
 
  data capture
 
hello, i am trying to send a data array to my PC from the handyboard thru the serial cable. a couple months ago, i was advised to use a terminal emulator to capture the data. this has not worked, however. i was told about using a null modem cable (...)

  HOW TO UNSUBSCRIBE
 
It appears to be time for the periodic unsubscribe reminder. In order to unsubscribe from the HB Mailing List, you must send a request to Fred Martin. He is the only person who can take you off the list. Ha ha ha ha!!! Try to guess his email (...) (26 years ago, 19-Oct-98, to lugnet.robotics.handyboard)
