Software using library:
* Alternative OpenFrameworks GUI
See for information
* Thanks to Jonas Bengtsson for OSX support and binaries
* Thanks to Andrew Solomone for the full-color knitting style
* Thanks to Varvara Guljajeva and Mar Canet for inspiring the project
* Thanks to Steve Conklin for information provided at Antitronics
* GUI relies on SDL2 and FreeImage
== WINDOWS USERS =====================================================
Just download everything in the bin-win\ folder, put it anywhere you
like, then run gui.exe. This has everything you need to quickly get
patterns onto your machine.
== MAC USERS =========================================================
OSX binaries can be found in the bin-osx/ directory.
Jonas, would you like to put in a word here?
== LINUX USERS =======================================================
Linux binares can be found in the bin-linux/ directory.
This requires a modidifed SDL2 library to add xDnD support.
Tested under Ubuntu only.
Still no serial port detection effectively making the program useless
for linux at this point. HELP WANTED!
The modified SDL2 .so file must be placed in the library search path.
Sorry for this odd procedure. HELP WANTED!
== FILES =============================================================
bin-X/ Binaries/executables for operating system X
lib/ Source files for the disk image manager/emulator
cli/ Source files for command line interface
gui/ Source files for graphical user interface
doc/ File/memory layout description
ptn/ Sample patterns as both original bmp and raw
win-###-make.bat Build ###:cli/gui program (windows batch file) Build ###:cli/gui program (linux shell script) Build ###:cli/gui program (osx shell script)
Want to help out by creating makefiles? Let me know!
== HOW TO USE GUI UTILITY ============================================
Sorry, no proper documentation available at this point. HELP WANTED!
It is however fairly straight forward!
1) Install the application (os dependant process) and launch it.
2) Click FORMAT and select your machine
3) Drag pictures (24-bit GIF, PNG or TIFF) into the window
Make sure the pictures are of size STITCHESxROWS pixels.
Pictures with two colors will import as single color.
Pictures with different colors will import as multi or full color.
Multi-color: pictures with only one contrast color per row
Full-color: pictures with several colors on one or more rows
Full-color requires special stitching procedure
4) Verify import by clicking pattern in list on the left, then EDIT.
5) Click EMULATE and select the correct serial port in the list
6) Use the knitting machine to load from disk (track #1 only)
== HOW TO USE CLI UTILITY ============================================
The CLI utility can be considered outdated, but is still useful when
you need to make patterns on a new machine and store them as a file
for analysis. The GUI does not provide this functionality.
Compile and launch knit executable.
Typing ? or help will give
?/help show this
r/read read in data from file
w/write write out data to file
m/machine select knitting machine
f/format clear all tracks
t/track set working track
a/add add pattern to track
s/show display content of track
i/info additional track info
e/emulate emulate floppy
q/quit end program
x/halt halt on errors
read - Reads image on disk to memory
The file can be either disk image or folder with emulator files.
Entering the name of a file will read it as a disk image, ie:
filename> sample/1.img
Entering a folder name, ending with a (back)slash, will read
Tandy FDD1 emulator file folder, ie:
filename> fddemu/img/
write - Write memory to image on disk
The file can be either disk image or folder with emulator files.
See "read" command for more info.
machine - Select knitting machine
This will show the currently selected machine as well as list
the available/supported machines.
After listing, you are prompted to select a new machine and
this is selected by typing the short name of the machine
you wish to use, ie:
machine> kh940
format - Clear computer ram contents
This will delete everything currently contained in memory and
ready the program for input of a new file.
track - Set working track
The machine can store patterns in two separate tracks and this
is chosen when saving/loading from the machine.
This will sets the current working track for add, show and
info commands.
Tracks are entered as a number between 1 and 2, ie:
track> 1
add - Add a pattern to memory
The pattern is read from a raw image file, ie:
filename> patterns/903.raw
See doc\raw_format.txt for a description of the format.
show - Show patterns contained in memory
This will list all available patterns and to into pattern
display mode. In this mode you get the following promt:
instead of the regular one.
To exit this mode enter d, done or simply enter a blank line.
While in this mode, enter the pattern number of an available
pattern to print out a graphical representation of the
pattern as well as its binary data representation.
info - Shows additional non-pattern information
This will display all important fields in the currently
loaded file and run a verification suite against all of
the know values.
Verifications are done against the most common and verified
to work values that have been downloaded from the machine.
Therefore it MAY give FAIL on "write pointer" entries and/or
the "loaded head" entry for some files because the machine
sometimes inserts a 0x00 byte between patterns which causes
a mismatch of 1 for these values. Exactly when/why this is
done is uncertain, but it is not needed when writing patterns,
so it may actually be a bug in the machine.
Additionally, MOST parameters WILL give FAIL on a blank
formatted file, regardless if done via device or this
For a file generated using this program all parameters
should give OK before attempting download.
emulate - Start floppy emulator
This will ask for a serial device and the format is different
depending on your system. For linux-flavors, it will usually
look like:
serial device> /dev/ttyS0
For windows, it will look something like:
serial device> COM1
After entering a serial device, the program will go into
floppy emulation mode.
You can exit this mode by sending a SIGINT, which is usually
Ctrl+C on most systems.
While in this mode, you can use the knitting machine to save
or load data into program memory, which can first be build
using add or read using read.
After saving from the machine you can keep it with write.
quit - Self explanatory
Go outside and enjoy the weather
halt - Enable/disable halt on errors
Enabling halt on errors is good for command line execution
== CLI BATCH EXECUTION ===============================================
All commands can be executed from command line, for example:
knit x a ptn/tile.raw a ptn/inca.raw a ptn/text.raw w test.img q
Will do the following:
* Enable halt on error
* Add ptn/blocks.raw as #901
* Add ptn/inca.raw as #902
* Add ptn/text.raw as #903
* Write disk image to test.img
* Quit
In addition commands can also be piped in, or typed manually in
succession at any prompt within the program.
