All,

I've just uploaded Butterfly BASIC for the MSP430 to our website--it
wasn't doing anybody eny good languishing on my hard disk.

Butterfly BASIC is a small BASIC interpreter for the MSP430 which stores
its program in FLASH and uses very little RAM.  It's released under the
GPL, and compiles with CrossWorks for MSP430 and runs on a selection of
boards, e.g. the SoftBaugh ES449 and DIr169.

There is some documentation, but not enough as I would like.  As always,
the code is pretty good, the documentation lacking, and I've had no time
to work on it.  I'll answer questions on it, but not of the sort that
would lead me to do another port.  If somebody else wants to take up the
baton, that's fine.

Have fun!

Geez, eny.  That's what you get typing quickly.  :-(

Where is it located, Paul?

Thanks in advance,
Jon

It's in small print near the right edge of the website, but
here's a 
direct link (took me awhile to find it too):

Ah!  I was thinking that by "our website" that Paul meant the yahoo
msp430 one,
where files can be stored there.  Cripes!

Thanks, Adam!

Hi Jon,

Sorry, thought it was obvious in the right-hand column, but I realised
afterwards I should have put in a URL:

http://www.rowley.co.uk/msp430/basic.htm

Rgds,

I have a different viewpoint of "our", obviously.  :-)

Don't snigger at the code.  The thing I don't like about the code is
the
flash handling for program storage, which is far too opaque.

The interpreter tokenises the basic program and pre-checks it for
mismatched control structures (as far as it can) before running.

If the interpreter is better placed somewhere else, for community
effort, that's fine by me.  I don't think the Y! file area is a good
place to store it, but a link to it or a sourceforge project would be
ok.  I was going to get graphics primitives running on a DIr169
connected to a Nokia 3310 display, but no time, unfortunately.

Implementing a floating-point BASIC isn't that difficult either, but
integer BASIC is enough for my use.
