LINUX
- CLIENT
gcc client.c -Wall -Werror -Wextra -o client
- SERVER
gcc server.c rs232.c -Wall -Werror -Wextra -o server
WINDOWS
- CLIENT
gcc client.c -Wall -Wextra -lwsock32 -o client
- SERVER
gcc server.c rs232.c -lwsock32 -Wall -Werror -Wextra -o server
Launch
Server
Server can be launched with 1 or 2 input parameters. The number of parameters determines what mode will be used - manual or automatic mode.
port - specific number to identify communication processes of server
[config_file] - configuration file with exact name of variables - check config.cfg file as example
Manual mode
- server waits for input commands from client, sends them to laser sensor and returns results back to client
./server <port>
Automatic mode
- server loads variables from configuration file config.txt, starts measuring and sends results to client continuously.
./server <port> [config_file]
Client
Client has to be lauched with 2 input parameters. If server is in manual mode, the client always loads input commands from commands.txt.
IP address - IP address of server the client tries to connect
port - port number of server
./client <IP address> <port>
Demo
Demo program demonstrates how to create client-like program, which can connect to server in automatic mode and process resulting data.
Building
UNIX - gcc demo.c -Wall -Werror -Wextra -o demo
WINDOWS - gcc demo.c -Wall -Wextra -lwsock32 -o demo
Launch
No input parameters.
Macros defines multiple variables:
#define IP_ADDRESS "192.168.0.101" // IP address of server
#define PORT 32500 // server port number
#define MAX_VALUE 1265 // upper limit to compare (depends on used units)
#define MIN_VALUE 1200 // lower limit to compare (depends on used units)
