The Century Software PDA ScreenTop provides an environment for you to easily add PDA applications to your PDA suite.
Before you can add an application to your device, you must wave the following:
A device running running Linux and Nano-X
Century Software PDA SDK installed on your development machine
An application you want to include on the screentop compiled for the device's specific processor
A 48x48 icon for your application in GIF format
To add an application to your device, do the following:
Add your application and any additional files it needs to the filesystem directory structure on your development machine. For example, you might put the application in the /usr/bin directory.
Edit the /etc/config.nxscrtop file by adding the following:
In the [Desktop] section, add
Create a new section:
[<appname>] exec=<path to application> icon=<path to icon> title=<application title> args=<command line arguments>
Create new filesystem files for any directory structures you changed (probably usr and init). For example, on the iPAQ you would create new CRAMFS files.
Upload your new files to the appropriate location in the device's FlashRAM.
Restart the device and launch your application from the screentop.
