-====== Brother KH-930e knitting machine ====== 
-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://​​index.php?​main_page=product_info&​cPath=18&​products_id=70&​zenid=08edecd591934eebcc4993c01b0259d6|FTDI cable]] 
-  * 2x4 connector part number [[http://​​scripts/​DkSearch/​dksus.dll?​vendor=0&​keywords=WM8036-ND|WM8036-ND on Digikey]] 
-==== Change '​polarity'​ of the FTDI cable ==== 
-FTDI cables have standard '​inverted'​ TTL (zero is 3-5V and one is 0v) but the KH930E requires the opposite. Luckily its very easy to fix this by reprogramming the software. 
-You will need a copy of [[http://​​Resources/​Utilities.htm|FTDI MProg ]] (windows only) and your FTDI cable. Plug in the FTDI cable into your windows computer and [[http://​​Drivers/​VCP.htm|install the driver that matches your computer best]] 
-[[http://​​learn/​breakoutplus/​ftdifriend.html#​installing_ftdi_drivers|Please read our detailed tutorial on installing the driver here]] then come back when the driver is installed 
-Now download [[http://​​Resources/​Utilities.htm|FTDI MProg]] and run the program 
-==== Rewire the connector ==== 
-  * Re-situate the pins from the FTDI header connector into the 2x4 connector. [[http://​​chumbyhackerboard/​serial|This chumby tutorial]] shows how to disconnect them from the original header. 
-===== Python code ===== 
-  * Available on [[http://​​adafruit/​knitting_machine|github]] 
-  * Based on [[http://​​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 
-===== 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. 
-===== Outside resources =====
