Re: [Amforth-devel] amforth-1.3 on atmega8

[<ha...@hu...>]

Hello Matthias,

thanks for your quick reply.  The problem has been the clock.  At 8
Mhz, 9600 are not really attainable and I guess that the AVR just
received garbage when I was trying to define a word.  I installed a
3.6864 Mhz xtal and now things work on the ATMEGA8L-8PI just fine!
Great!  Thanks for this very cool piece of software.

Is there any information available on how one would proceed to get an
application running with amforth?  I see that there are several files
in the blocks/ subdirectory that appear to be Forth libraries, but how
would I add those files to the Flash image?

Is the svn repository available for public read access?

Again, thanks for your support and this great piece of software!

-Hans
