 | | Dissecting a mouse for the Handyboard

|
Hi All, Has anyone dissected a PC Mouse, and interfaced it with the Handyboard, to use it as a directional and speed indicator. Any information on how the mouse works or how it can be used with the handyboard would be appreciated. Thanks Michael (27 years ago, 10-Jun-97, to lugnet.robotics.handyboard)

Try going to the shutdown menu for Win95. Select restart in Msdos mode. Once the system gives you the dos prompt, try hbdl again. (...) may take a min but how much speed do you need?... if that works... try 19200, 38700, blah blah blah... (...) (...) (27 years ago, 9-Jun-97, to lugnet.robotics.handyboard)

Hmm.. Seems my reply address was wrong in my original message, so i'm re-posting this with the right address. (Thanks Fred for pointing this out). I'm working with a robot where weight is very important. I was wondering if anyone had the exact (...) (27 years ago, 9-Jun-97, to lugnet.robotics.handyboard)

(...) Paul, What you want to do is easy. All you need to do is get a small assembler routine which uses the Input Capture feature. Set the IC via registers to trigger when a rising pulse begins, it will stash the time and strigger an interrupt. Then (...) (27 years ago, 9-Jun-97, to lugnet.robotics.handyboard)

(...) 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)

| | System Interrupts & frequency counting
|
|
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)

I'm working with a robot where weight is very important. I was wondering if anyone had the exact weight of the Handy board, Miniboard and the Nicad battery pack that the Handy board uses? Thanks, Daryl Boyd (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 (...)
