Tell me more about designing WristApps…

Writing custom WristApps gives you the most flexible solution for your specific watch-based requirements. You need to have the following:

∙Timex USB Datalink Watch;

∙PC with Windows OS and a USB port;

∙Text file editor;

∙Experience in writing assembly language and debugging code;

∙Patience to read through some thick documents.

Let’s build the sample Counter WristApp…

This will guide you to building the Counter WristApp source files provided in the WristApp SDK directory.

1.Installation. You need to do this only once. Download the WristApp SDK Installer and execute it. This will setup the required directories and utilities required to build the WristApp. This also installs the sample application that we will be building in this guide.

The WristApp SDK files are located in the root directory at C:\M851.

2.Coding the WristApp. Actually, the sample Counter WristApp is already coded, debugged and tested. The design process from start to finish is detailed in the document “M851 Counter WristApp Design Guide.pdf”.

The source files are located in the directory: C:\M851\APP\COUNTER. Open up file explorer to the

directory and you will see three directories: header directory (H), source directory (SRC) and the build directory (BUILD). Take a look at the files using your preferred text editor. Do not make any modifications to the files.
