Artisan helps coffee roasters record, analyze, and control roast profiles. With the help of a thermocouple data logger, or a proportional–integral–derivative controller (PID controller), this software offers roasting metrics to help make decisions that influence the final coffee flavor.

INSTALLATION

(see the Artisan project Wiki at GoogleCode for the latest installation instructions)

o Windows

Artisan for Windows needs a Visual C++ runtime library (file) from Microsoft. This is automatically installed from v0.6 on by the Artisan installer. If Artisan cannot start it will open a Windows error. This is because your computer is missing this file. If you get a window error when you try to start Artisan, install this program:

Microsoft Visual C++ 2008 SP1 Redistributable Package (x86)

http://www.microsoft.com/downloads/en/details.aspx?familyid=A5C84275-3B97-4AB7-A40D-3802B2AF5FC2&displaylang=en

If artisan starts when clicking on artisan.exe (a window pops open with many buttons), then your computer already have this file and you don't need to install anything. Newer OS like Windows 7 come with this file.

o Mac OS X (>=10.6.x)

• Install USB/serial driver for your meter . for Omega meters download and run the FTDI VCP OS X installer http://www.ftdichip.com/Drivers/VCP.htm . for Voltkraft meters using the original Voltkraft USB cable it is the CP210x driver from Silicon Labs http://www.silabs.com/products/mcu/Pages/USBtoUARTBridgeVCPDrivers.aspx . some other serial2USB dongles use the Prolific PL2303 chips http://prolificusa.com/pl-2303hx-drivers (on Mac OS X 10.8 and higher some reported that the org. Profilic driver failed to work, but the [http://sourceforge.net/projects/osx-pl2303/ NoZAP driver] did work)
• Download and run the Artisan OS X installer (on OS X >=10.8 Mountain Lion you need to tick "Allow applications downloaded from Anywhere" in the Security & Privacy Preference Panel to start the app)
• Double click on the dmg file you just downloaded
• Double click the disk image which appears on your desktop
• Drag the artisan application icon to your Applications directory

o Linux

The Linux package is compatible with Ubuntu/Debian and CentOS/Redhat (glibc 2.12). For now, we simply offer a .deb Debian package as well as an .rpm Redhat package that you have to install manually. This can be done by either double clicking the package icon from your file viewer or by entering the following commands in a shell.

Installation on Ubuntu/Debian

sudo dpkg -i artisan_.deb

Uninstall on Ubuntu/Debian

sudo dpkg -r artisan

Installation on CentOS/Redhat

sudo rpm -i artisan_.rpm

Uninstall on CentOS/Redhat

sudo rpm -e artisan

In case you run into permission problems such that Artisan is not allowed to read or write to the selected /dev/USB device, you might need to add your account (username) to the dialout group via

sudo adduser dialout

After this command you might need to logout and login again. Try

id

that your account was successful added to the dialout group.
