Thanks for the info Rainer. I ended up picking up a Logic Probe from Radio Shack as it was only $18. Even if its not top of the line, it should work plenty fine for this job (and more later).

Hi Scott, as I mentioned before i only assembled some 6.270 boards, but no handyboard. So what's follwing is only what i guess. I can't check this out here.

Hi Scott, I assembled three 6.270 boards (kind of grandpa of handyboard) some month ago and didn't need an Oscilloscope or a Logic Probe. I guess you'll only need such things if you run into trouble with getting started with your handyboard. So, try (...) (23 years ago, 26-Aug-01, to lugnet.robotics.handyboard)

Howdy all, I'm getting ready to finally begin assembly of my HB and I have a question regarding the "necessary" tools for this.

Hi To solve your problem you don't need to learn s19 code. You must only something like encoder0_low_threshold= 75; in your program (c and nod s19). You must only replace the 0 (zero) according to your used analog port. For further information refer (...) (23 years ago, 22-Aug-01, to lugnet.robotics.handyboard)
