Developing Your First Application
We use the tcps2 example to illustrate how to build an application. The procedure outlined in the
following subsections will show you how to build a TCP server program plus serial port
communication that runs on the DA-660.
Testing Environment
The tcps2 example demonstrates a simple application program that delivers transparent,
bi-directional data transmission between the DA-660’s serial and Ethernet ports. As illustrated in
the following figure, the purpose of this application is to transfer data between PC 1 and the
DA-660 via an RS-232 connection. At the remote site, data can be transferred between the
DA-660’s Ethernet port and PC 2 over an Ethernet connection.

Compiling tcps2.c
The source code for the tcps2 example is located on the CD-ROM at
CD-ROM://example/TCPServer2/tcps2.c.
Use the following commands to copy the file to a
specific directory on your PC. We use the directory
/home/da660/1st_application/
. Note that you
need to copy 3 files—
Makefile, tcps2.c, tcpsp.c
—from the CD-ROM to the target directory.
#mount –t iso9660 /dev/cdrom /mnt/cdrom
#cp /mnt/cdrom/example/TCPServer2/tcps2.c/home/da660/1st_application/tcps2.c
#cp /mnt/cdrom/example/TCPServer2/tcpsp.c/home/da660/1st_application/tcpsp.c
#cp /mnt/cdrom/example/TCPServer2/Makefile.c/home/da660/1st_application/Makefile.c
Type
#make
to compile the example code:
You will get the following response, indicating that the example program was compiled
successfully.
