Hi, I bought a Polaroid 6500 for x-mas and now I’ve got two questions: 1) In the Handy Board Interfacing Diagram of the Polaroid 6500 at the Handyboard page V+ is connected to the pin 9 of the Polaroid 9-pin connector.

Hi all, The model this is written for is a biped walker with each leg driven by it's own motor. The PB is a Scout. It uses a modified version of ping.nqc to do IR proximity detection. When it detects that there is an obstacle, it should back up, (...) (24 years ago, 3-Jan-02, to lugnet.robotics.rcx.nqc)

John, I just did the same test, I think what Fred was saying is that IC sets the 0x8000 to accept a startup program if one is loaded. If I poke a 0 to that address then load any program it sets back to 1. I think he was wandering if your IC version (...) (24 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

Fellow Lugnuts, Doe anyone want to purchase a 74HC244 (U5) that "kinda works" ? YES, YES, believe it or not, U5 was my problem !!

Matt, The only mod I've made to my HB is to cut the motor power supply "+" trace and use a separate motor power supply. See my post/response to Dan for my explanation of that. After reading your START button question, I triple checked. I don't (...) (24 years ago, 3-Jan-02, to lugnet.robotics.handyboard)

Dan, Yes, I did cut the trace for external motor power. I know the HB and the motor power "+" sources are isolated because I not only checked with a VOM, but I removed the motor supply batteries and when I run my motor test program (remember, no (...)

I'm trying to track down a good suite of development tools for the H8. So far I've found out that the Hitachi Embedded Workshop is $1100. Since the main tool that I'm interested in is the simulator (I can use the GNU tools to write code) I'm (...) (24 years ago, 2-Jan-02, to lugnet.robotics)

Wow, What a bugger! This is one of the strangest cases I've seen. Works fine while connected, but not when reset. Works fine on my board either way. Memory and 68HC11 have been traded out. Scope shows no voltage drop at Mem-power durring reset. Both (...) (24 years ago, 2-Jan-02, to lugnet.robotics.handyboard)

I have had this problem with one or two of my RCXs. I think the problem is that the CPU/RAM get into a "funny" state as the supply voltage drops after the batteries are removed. Once in this state, re-inserting batteries just brings the power up to (...) (24 years ago, 2-Jan-02, to lugnet.robotics)
