## About
|
||
|
|
This repository contains source codes for client-server network application capable to communicate with distance laser sensor DLS-C 15 via RS-232 interface, which was implemented as a part of bachelor thesis.

## Building
|
||
|
|
Implemented and tested on:
|
||
|
|
| Platform | OS | compiler |
|
||
|
|
|-----------------|---------------------------|-------------------------------------------------|
|
||
|
|
| Linux | Ubuntu 20.04.1 WLS2 | gcc version 9.3.0 (Ubuntu 9.3.0-10ubuntu2) |
|
||
|
|
| Windows | Windows 10.0.19043 | gcc version 11.2.0 (MinGW-W64 x86_64-posix-seh) |
|
||
|
|
| Raspberry Pi | Linux raspberrypi 5.10.17 | gcc version 8.3.0 (Raspbian 8.3.0-6+rpi1) |
|
||

|
#### LINUX
|
||
|
|
* CLIENT
|
||
|
|
- `gcc client.c -Wall -Werror -Wextra -o client`
|
||
|
|
* SERVER
|
||
|
|
- `gcc server.c rs232.c -Wall -Werroe -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:
|
||
|
|
|
||
|
|
```c
|
||
|
|
#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)
|
||
|
|
```
|
||
