Announcement of picoTK 0.02

[Thomas Gallenkamp]

Hello !

I just revised the picoTK HOWTO and added documentation for the API (see
http://picotk.sourceforge.net).  
I started this in an effort to replace a MS-DOS/Borland BGI based system
with RTEMS. The goal is to replace an "embedded PC" by a more compact
683xx system. But I unfortunately didn't found a GUI library with few
enough
functionality. That's why I decided to do it myself. There are two things
in picoTK which I am most proud of:

Firstly it can use any X character font (copyrights might restrict the
usage to some PD/GPL fonts though). Allowing very good character quality
(much better than what Borland BGI had 12 years ago).
Secondly it implements a "terminal box" in which you can readily print
using "printf()". The terminal currently only understands "line-feed" and
"carriage-return" - but I am working on a more complete VT100 emulation. I
have compiled a bootable demo floppy disk image together with RTEMS
4.5.0beta, its on the picotk page http://picotk.sourceforge.net. 

I use RTEMS since 1996, when we started a robot project (68332 based, see
http://gupeto.sourceforge.net) and think it will have a great future.

Give it try

>  description:
>  picoTK is a C GUI toolkit that requires only a minimum of memory
> resources. It is intended for embedded system use, especially for
>  (but not limited to) the RTEMS realtime kernel. It is in no way
> comparable featurewise to a real full blown windows toolkit like Qt or
>  nanoX; it rather provides simple drawing primitives like lines, filled
>  rectangles, characters, and pixmaps. (But that is what many embedded
> applications might ask for.) It directly works on tailored
>  framebuffer hardware. A Linux framebuffer emulator is supplied as part
> of the kit, making evaluation (and emulation!) possible without
>  having a realtime OS and custom hardware.
>   
>  Changes:
>  New framebuffer drivers for 1bpp, 4bpp, and 8bpp color depth, generic
> frame buffer emulator for all supported color depth, a HOWTO
>  describing configuration and installation, and Makefile examples
> showing RTEMS and cross-compiler usage.
