Topfield Application Program
If you are good at programming with C language, you can
make an executable program to run on the digital receiver.
We call this a Topfield Application program (TAP). In mak-
ing a TAP, it is recommended to use Diab compiler of Wind
River, whose website address is http://www.windriver.com.
Some variants of gcc compiler also might be available as a com-
piler for TAPs. You can get the Application program Inter-
face (API) libraries for TAPs from the Topfield website, http:
//www.i-topfield.com.
Your TAPs will be run under the following conditions:
• Their extension name is tap. If they have any other ex-
tension name, they will be ignored.
• They are in the Program Files folder. If they are in other
folders, they will be ignored.
As to how to transfer your program to the digital receiver, refer
to §7.7.
