+
+## 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)
+```
