the bitkanone is intended to control WS2812B Led-Strips as displays, it features more stuff around mecrisp-Forth for stellaris
mecrisp is a Forth system written by Matthias Koch. bitkanone itself is written by Gerald Wodni

Program mecrisp into the lm4f120 using lm4flash (might require sudo):
$ tools/lm4flash/lm4flash tools/mecrisp/lm4f120/mecrisp-stellaris-lm4f120.bin
Merge all source-code into one file for an easy upload:
$ ./merge
Start a serial-terminal (picoterm)
$ ./terminal
Instruct picoterm to upload the merged file:
<ctrl-a><ctrl-s>bitkanone.fs<return>
on ( -- ) set all leds to full white
off ( -- ) disable all leds
red ( -- ) set leds to soft color ($1F instead of $FF)
yellow --//--
green --//--
cyan --//--
blue --//--
magenta --//--
white --//--flush ( -- ) write buffer using the current flush-target (most likely z-flush)
buffer-off ( -- ) clear buffer
buffer! ( u -- ) set all pixels to ugame-line ( n -- )
gol-step ( -- ) compute single gol-step
g ( -- ) alias for gol-step ( for easy demonstrion )
game-steps ( n -- ) compute n gol-steps
gol-off ( -- ) clear all life
g! ( n-x n-y -- ) spawn live in cell x yglider ( -- ) smallest moving object / hacker-symbol
lwss ( -- ) light-weight-space-ship
gol-line ( n -- ) line with n elements
die-hard ( -- ) small startup colony
acorn ( -- ) lives forever on infinite grid, not here :/
quadpole ( -- ) static
schick ( -- )glitter ( -- ) displays a nice glitter-fire-like effect until a key is pressed
glitter-color ( -- a ) color variable, standard value: $FFAF3Fpnm-here ( -- ) parses an image in pnm-ascci format, some images can be found in /data/images. Just send them with <ctrl-a><ctrl-s>data/images/1701.ppm<return>(sudo) tools/lm4flash/lm4flash tools/mecrisp/lm4f120/mecrisp-stellaris-lm4f120.bin

On power on the the test pattern will be displayed for one second ( blue-waves with a red dialogal line originating from the top left. After that the bottom left (1st) Led will turn green. If you press any key from now on within 5 seconds, it will turn red and you will be greeted by "Human presence deteced". If no key is received, the ev-demo program is launced and will loop until any key or reset is pressed.
Have fun! ;)
