knitty-gritty 0.0.1

What Doesn’t Work?

• Adding data to the memo display.

• Validating that the pattern fits within the machine’s working memory.

Platform Support

Only tested on OS X, but should work out of the box on both Windows and Linux given that you have the software requirements listed below installed. Please let me know if it does not - preferably with a pull request fixing the issue :-)

Downloading Patterns from the Machine

# First, find your USB cable:
ls /dev/tty.usbserial-*

# Replace the file below with the name you found
# The last parameter `patterns` is the folder where your patterns should be saved
knitty-gritty emulate-folder /dev/tty.usbserial-A7XTW5YZ patterns

If this is the first time you run knitty-gritty, you should download all patterns from the machine first. On a KH940, this is done by entering CE, 552, STEP, 1, STEP. When this is done, the machine should beep (as it always does). Quit Knitty-gritty by pressing Control-C. The pattern images should appear in the folder you specified.

Now you can modify/add/remove patterns as much as you like. Just drop them in the folder together with the other patterns.

Uploading Patterns

When you’re done with fiddling with the images, you should upload them:

# Replace the TTY-parameter with the cable you found above.
knitty-gritty emulate-folder --no-save /dev/tty.usbserial-A7XTW5YZ patterns

The --no-save argument tells Knitty-gritty to not save any files to the folder on the computer. This is a safeguard against removing/overwriting patterns if anything goes wrong.

To load the patterns on the machine, enter CE, 551, STEP, 1, STEP and wait until it beeps.
