Running a TCP/IP application on an ADSP-BF537 EZ-KIT Lite
To enable multiple clients (computers) to connect concurrently to the
same host (the EZ-KIT Lite), TCP/IP applications typically use multiple
operating system threads of execution as follows.
1. The main application thread begins polling the port number(s) rel-
evant to the application.
2. When a client connects, a new "worker" thread is spawned to inter-
act with the client.
3. Meanwhile, the main application thread continues polling for new
connections.
The following procedure creates a Caesar Cipher application from the
skeleton template. The steps implement a thread to interact with the cli-
ent, producing a Caesar Cipher on input received from the client.
Alternatively, the project

Started Examples\Part_2_1\Caesar_Cipher.dpj
if you are unconcerned about the details herein and want to avoid typing
in source code. (If you load the project, skip the following procedure).
To create a new thread type,
1. From the Kernel page of VisualDSP++ Project window, navigate
to Kernel–>Threads–>Thread Types. Right-click and select New
thread type. Type
leave Source File and Header File as is, automatic source code gen-
eration as Yes, and leave the Language as C++
2. Click OK. The new thread displays in the VisualDSP++ Kernel
tab.
3. Switch back to the Project page and open the newly-created source
file
