In this section we will download and install the software that emulates a disk drive to the knitting machine. You can run this software on any kind of computer, mac/win/linux

====== Python code ======
Now that you have the cable running, its time to download the software. Visit the Adafruit [[http://github.com/adafruit/knitting_machine|github]] repository and click on **Download** to download the source code. 

//This code is based on [[http://www.antitronics.com/wiki/index.php?title=Electroknit_Technical_Information|Steve Conklin's knitting machine code]] which is totally awesome but doesn't support pattern insertion. Still, check out his site for a lot of detailed information.// 

Download the file and unzip it into a directory that is easy for you to get to. For windows, we're going to stick the folder in **My Documents** in a folder called **brother** but if you are comfortable with command lines put it where-ever you'd like!

You will need Python installed to run the code. To see if you have Python installed, open up a command line and type in **python**. If you're running Windows you probably don't have it, so download it from [[http://www.python.org/download/|the official Python site]]. You'll also need [[http://sourceforge.net/projects/pyserial/|PySerial (serial interface for python) from http://sourceforge.net/projects/pyserial/]]

Open up a command line (windows) or Terminal (mac) or xterm (linux) and **cd** to the **brother** directory and then type in **ls** (or **dir** if **ls** doesnt work) to list all the files

===== Determining the serial port =====

Now we need to figure out what the name of the FTDI cable is. This process differs a little for Mac, Linux and Windows people.

Under Mac, in the Terminal window, type in **ls /dev/cu.* ** which should give the following responses or so

The name we are looking for is **/dev/cu.usbserial-XXXX** where the X's are going to be unique for each cable. Copy and paste the name into a text file so you'll remember it for later.

For Linux/Unix type **ls /dev/ttyUSB*** into a terminal window, you should see a device file called something like **ttyUSB0**

If you are using Windows, go to the **Device Manager** (From the **Start Menu**, select **Settings->Control Panel**. Double click on **System** and select the **Hardware** tab. Then click on the **Device Manager** button)
