I've been looking into the HandyBoard, and it looks great. I'm
wondering if I could get some opinions here. A friend of mine and I are
going to build a robot, and we are trying to decide if we should go with
the HB, or make something else. I know this is the HB list, so please
feel free to share your experienced opinions.
My friend is biased towards the 8051 derivatives. He has already done
some stuff with the Dallas Semi chip called 'Speed it uP' which is a
6mip (!) 8051 derivative. I'm a game developer (not a hardware guy as
you can probably see already), so to me, lots of speed in the micro
sounds good since I could implement complicated (AI, fuzzy, complicated
path-finding) routines for controlling the Bot, without worrying about
the thing bogging down.
The one compelling reason he gives for using the 6mip 8051 thing is that
he already has a nice C compiler that produces optimized code (besides
having a pretty windoze interface, etc.). And of course he's familiar
with it already.
To me, the fact that you can buy a HandyBoard prebuilt sounds good. But
the idea of Interactive-C sounds bad to me, since it's pcode, and
probably fairly slow (is it? Has anyone tried to do complicated things
that IC can't keep up with?) Is there any other 68hc11 C compilers out
there for a reasonable price? I haven't seen any yet.
So what do you all think? HandyBoard and InteractiveC, or 6mip 8051ish
thing with homegrown board?
Which do you think is easier, more expandable, more powerful?
Sorry this was a long post, and thanks for any advice you can offer,

| (...) I believe the answer is 'yes'. Which may sound silly but may turn out to be the answer you settle on. Tom's comments about the power of 8 bit computers is spot on. They eventually lose their ability to 'keep up' as it were, however they are so (...) (27 years ago, 23-Apr-97, to lugnet.robotics.handyboard)

| (...) For a decent and inexpensive 68HC11 ansi-C compiler you should look into ICC11 from imagecraft. I think they have a dos version for around $50 and a windows version for around $100. I used it in a project with the motorola 68HC11 evb and I was (...) (27 years ago, 23-Apr-97, to lugnet.robotics.handyboard)
