Hi Scott,
I tried the socket interface but it seems that GPSim response is always
"+ACK+ACK" ....
is the Socket interface really working ?
I have found this comment in the Script folder :
/*
Scripting
client.cc - a program to demonstrate gpsim scripting.
The purpose of this program is to demonstrate how one might write a
script to perform regression testing on an algorithm. In this
example, the algorithm is one that squares an 8-bit number. It is
implemented in the PIC source code gensquares.asm.
The scripting mechanism is implemented on top of a socket
interface. When gpsim is started, it will act as a server and began
listening to clients. This client will initiate the communication
link. It probably goes with out saying, but gpsim needs to be
running before this client script will even work!
Once this client establishs a communication link, it will proceed to
set up the simulation environment and perform a regression test.
Technical details:
The scripting interface is implemented with a gpsim specific
protocol. This protocol is somewhat analogous to gdb's
protocol. gpsim's protocol operates in two modes. In one mode,
character strings are sent across the socket interface and sent
through the command line parser. Thus, it's possible to issue any
gpsim command through a socket that can be typed at the command
line. As of this writing, this interface is only uni-directional
though. In other words, the client can only issue commands, but
can't see the response. However, the other mode of the protocol
allows bi-directional communication. This other mode ties directly
into gpsim symbols and attributes.
In the attribute mode of the protocol, there are two ways to
interface to the symbols. The first is by symbol name and the second
is by a 'handle'. For either one of these, it's possible to read and
write symbols. Handles are more efficient since they only have to be
processed only one. Accessing by name on the other hand, requires
string processing and symbol table accesses.
*/
and this one in the readme file there :
"NOTE: As of this writing, the Python scripts are not working!"
Are the Python scripts really working or not ?
can I use the socket interface Bidirectionnaly to issue command or must I
rewrite a wrapper arround the classes in files Protocol.xxx and
Client_Interface;xxx ???
