23. TM 24 internet & account & mbed.org .

24. TM 25 Set-up the Internet connection • Go into your computers WLAN connection manager • Login to network „USB Academy“ • Password is: „freescale“ • Open your browser and go to mbed.org • Remarks − Only port 80 is open, all others are blocked by a firewall − Only mbed.org and freescale.com are accessible

25. TM 26 mbed Basics • mbed is a online platform for fast, low-risk rapid prototyping • mbed under Apache 2.0 license and can used in commerciSDK is Open Source al projects with confidence • mbed is for starters, engineers, students, sales, marketing and distributors • mbed provides API libraries build on top of CMSIS* • mbed uses C/C++ and is portable to other IDEs • mbed works on Windows, Mac and Linux and will run under Internet Explorer, Firefox, Safari, Chrome, etc. *Cortex Microcontroller Software Interface Standard

26. TM 27 mbed Website Handbook The Handbook is the central portal to documentation. It links to introduction and getting started documentation and describes the API of the official mbed C/C++ libraries. This is the place we can find any documentation and information about mbed.

27. TM 28 mbed Website Cookbook The Cookbook is the central wiki that can be edited by any user, using the Wiki Syntax markup. This is the place we can build up a collection of libraries and components, information and tutorials. Things that can be made use of by everyone. The aim is for this to become a high quality resource.

28. TM 29 mbed Website Components The Component Database hosts reusable libraries for different hardware, middleware and IoT services that you can use with ARM Microcontrollers. These components can be used as building blocks for quickly developing prototypes and products. Components and the associated libraries, examples and documentation are created and added to the database by mbed developers, component manufacturers and service providers. The goal is to create a canonical database of rock-solid code and resources for every useful component that can be used with ARM microcontrollers.

29. TM 30 mbed Website Code Code is hosting code and libraries to use in our application. The contrent is contributed by mbed and the user community. It is split in 3 sections: most popular code, most active code and featured code and has a search functionality for the repositoy.

30. TM 31 mbed Website Questions The Questions section of mbed is designed to provide a high quality resource of common (and not so common) questions and answers. This means that instead of searching long forum threads for the answer to a query or problem, both the question and answer will hopefully be captured succinctly on a single page.

31. TM 32 mbed Website Forum The forums are for general discussions, or for open-ended questions which may have several possible answers. For specific answers to particular problems, try the Questions section.

32. TM 33 mbed Website Dashboard The Dashboard is the place to modify your profile and log all your activity. Your personal code repositories and public shares and your notebook.

33. TM 34 mbed Website Compiler This is where you write your code which runs on your mbed. This area is private to you and no one else can see it. Think of it as your local PC. Nothing can move from the mbed Compiler to the public website unless you tell it to.

44. TM 45 Serial Communication with a PC • The mbed Microcontroller can communicate with a host PC through a "USB Virtual Serial Port" over the same USB cable that is used for programming. • This enables you to: − Print out messages to a host PC terminal (useful for debugging!) − Read input from the host PC keyboard − Communicate with applications and programming languages running on the host PC that can communicate with a serial port, e.g. perl, python, java and so on.

45. TM 46 Check Serial Connection • Your mbed Microcontroller can appear on your computer as a serial port. − On Mac and Linux, this will happen by default. For Windows, you need to install a driver (../mbedWinSerial_16466.exe) • You need a terminal application on your computer like TeraTerm or puTTY. (../teraterm-4.78.exe) • Identify the serial port − Windows - Look under the "Ports" section in "Device Manager" (''Start -> Control Panel -> System -> Hardware -> Device Manager''). The name will be ''mbed Serial Port (COMx)'', where ''x'' is the number of the COM port allocated. − Mac OS X - Use the command ls /dev/tty.usbmodem* − Linux - Use the command ls /dev/ttyACM* • Set serial connection to 115200 baud, 8 bits, 1 stop bit, no parity
