| - | Adventures in communicating with the Brother KH-930e knitting machine! | ||
| - | |||
| - | ===== Make your own cable ===== | ||
| - | The kh930e is designed to work with a Tandy PDD1 floppy drive. We don't need it! Make your own cable to communicate between your computer and the machine. You will need: | ||
| - | * [[http://www.adafruit.com/index.php?main_page=product_info&cPath=18&products_id=70&zenid=08edecd591934eebcc4993c01b0259d6|FTDI cable]] | ||
| - | * 2x4 connector part number [[http://search.digikey.com/scripts/DkSearch/dksus.dll?vendor=0&keywords=WM8036-ND|WM8036-ND on Digikey]] | ||
| - | |||
| - | The FTDI chip in the cable needs to be reprogrammed and the header rewired to fit the knitting machine's serial port. | ||
| - | |||
| - | * Reprogram your FTDI cable using [[http://www.ftdichip.com/Resources/Utilities.htm|FTDI MProg ]] (windows only) (need specific instructions on this still) | ||
| - | * Re-situate the pins from the FTDI header connector into the 2x4 connector. [[http://wiki.ladyada.net/chumbyhackerboard/serial|This chumby tutorial]] shows how to disconnect them from the original header. | ||
| - | |||
| - | ===== Python code ===== | ||
| - | * Available on [[http://github.com/adafruit/knitting_machine|github]] | ||
| - | * Based on [[http://www.antitronics.com/wiki/index.php?title=Electroknit_Technical_Information|Steve Conklin's knitting machine code]] | ||
| - | * Includes scripts for emulating the floppy drive, previewing patterns, and converting images to new patterns. | ||
| - | |||
| - | ===== Backing up patterns/dumping memory from kh930e to computer ===== | ||
| - | * Start up the disk drive emulator in the command line. | ||
| - | * When "ready" lamp is lit, clear display with CE key, then prepare to save pattern data to "disk" by typing 552, then STEP. | ||
| - | * Display will go blank and then "ready" and "pattern no" lamps will light up with the "track" number 1 in the display. Press STEP. | ||
| - | * Machine will beep when finished, and the track data will now be in the "img" folder along with your emulator and other scripts. | ||
| - | * The emulator also makes a handy file-01.dat file to make it easy to preview the patterns using dumppattern.py. | ||
| - | |||
| - | ===== Creating new patterns ===== | ||
| - | |||
| - | ===== Putting new patterns on the machine ===== | ||
| - | * Start up the disk drive emulator in the command line. | ||
| - | * When "ready" lamp is lit, perform a memory reset by pressing CE key, then type in 888, then press STEP key. | ||
| - | * Clear display with CE key, then prepare to load new data into memory by typing 551, then STEP. | ||
| - | * Display should go blank, then "ready" and "pattern no" lamps should illuminate. Press 1 to indicate which "track" to load from the disk drive emulator, then press STEP. | ||
| - | * Machine will beep when finished. pick a pattern and knit as normal. | ||
| - | |||
| - | ===== Troubleshooting ===== | ||
| - | * If the RAM data has been corrupted, the screen will flash "888" and the machine will seem unresponsive. Hold down INPUT and STEP at the same time, and when the display should change. Perform a memory reset by hitting CE, 888, STEP. | ||
