91.308 Assignment 2: Intro to Palm OS Programming out: Mon Sep 19 due: Fri Sep 23

In this assignment, you will get a PC set up to do Palm development, build a “Hello World” Palm application, and run it using a Palm emulator.

It will be best if you have your own machine to do this assignment. If not, machines in the Engaging Computing lab (OS306) are available. Please contact me if you wish access to the lab.

1. Choose your development tools. I personally prefer command-line tools. For Palm, this is a port of gcc called PRC-Tools.

   The other option is the Palm OS Developer Suite (PODS), which is based on the open-source Eclipse IDE (from IBM) and the gcc/PRC-Tools package. The OS306 machines will have this installed.

   Note: PODS can not co-exist with a prior installation of Cygwin—it installs its own Cygwin, and it requires that you remove any existing one first. If you have Cygwin already on your PC, your options are (a) remove it and install PODS, or (b) ignore PODS and use the command-line PRC-Tools.

   See the course Palm OS resources page for download links.

2. Read the excerpt from the Lonnon Foster book that was handed out in class. This explains how to use the PODS software, and introduces two HelloWorld sample applications.

3. Compile/build Lonnon Foster's HelloWorld2 Palm application. Get it running on either a Palm emulator or a physical device.

   If you are using the GUI PODS environment, you need to create a new "managed make 68K C/C++" project, and then add the following files. Into your project, install these files from the gcc sub-directory of the Foster sample code:

   • Using File->Import->File System, get helloMain.c and helloRsc.h.
   • Using File->Import->Palm OS Resources, import from hello2.prc

   At this point, you should be able to build your application. It will build a .prc file in the Debug directory. Find this file on your hard drive and load it into the Palm emulator (right-click and choose Install Database).

4. Change the application's creator code to some other 4-character value (not all lower-case, since those combinations are reserved by Palm).

5. Now, extend it. Implement at least two new features. Choose from the following list, or invent something else of your own:

   • Split the name field into two fields (one for first name, one for last name), and have the “Say Hello” and “Say Goodbye” forms concatenate the two names.

   • Add a third alert, button, and message (e.g., “Hey There”).

   • Add a new icon to the existing About Hello World 2 form.

   • Create a second About-this-application form, and add it to the Options menu.

   • Add a slider or other UI widget to the main screen, and have it do something when activated.

6. Turn in your work by (a) zip or tar your source and your .prc application file into a single archive and put it in a reachable location on your CS account, (b) submit a hard copy cover sheet that gives a directory pointer to your work and explains in some detail what you did, (c) include a screen snapshot showing your application running on the Palm emulator, and (d) on your write-up, indicate the 4-character value you chose for your application.
