LT200 is our new product to control I/O via Internet.
It is also our application example that user can download source code form our web.
The control board inside LT200 is Mity-Mite module that contains our M6117D CPU.
So, we use X-DOS to be our operation system.
We also use our DOS libraries to develop. The related data are:
Use DSock to provide TCP/IP functions. It also provides a lot of examples for
programmer. We use the start-up project, DSOCK_AP, to start our development.
We start the development with DSock start-up project which already contains
web server, FTP server and TELNET server. We remove the TELNET server that
we do not need this function.
When use install LT200, the network configuration should be setup. At this time,
the TCP function may not work. Use UDP broadcast function is best choice for this.
Just plug network cable and user can use UDP setup program to initialize LT200.
Because of TCP property, user can use TCP to control LT200 every where in the
world. We define simple control protocol and write a Windows TcpCtrl program.
We will show your more detail later.
For some application, we do not what platform(Windows, Linux...) user use.
A web based control page is useful this. User can use any browser on any
O/S platform to control message. You can find some useful technical coding
on our source code.
Convert data between COM port and Ethernet like RSIP do is useful for some
special application. It works as host-based mode of RSIP. To do this is very
easy with our DSock and SerPort library.
We save all parameters in DSOCK.CFG. You will see how we save and reload
data from file with UDP setup protocol.
Bind all functions above. The LT200 main program is okay. After test, we use
MakeROM to build ROM image for Mity-Mite module. If you fix bug of your firmware,
you can use Update utility for DSock to upload new firmware via FTP function.
