| === ESP8266.ino === | === ESP8266.ino === | ||
| + | * <code c++> connectToWiFi() </code> | ||
| + | * Realizeaza conectarea la reteaua WiFi si asteapta o conexiune stabila. | ||
| + | * <code c++> httpGETRequest(const char* path) </code> | ||
| + | * Realizeaza conexiunea HTTP catre //path// dat ca argument. | ||
| + | * Realizeaza cerere HTTP de tip GET si returneaza rezultatul. | ||
| + | * <code c++> sendData() </code> | ||
| + | * Construieste pachetul de date - delimitat de caracterele //<// si //>//. | ||
| + | * Trimite pachetul catre dispozitivul conectat, prin interfata seriala USART. | ||
| + | * <code c++> setup(void) </code> | ||
| + | * Seteaza BAUD rate-ul. | ||
| + | * Apeleaza functia //connectToWiFi()//. | ||
| + | * <code c++> loop() </code> | ||
| + | * La intervale de 10 minute, este apelata functia //httpGETRequest(const char* path)//. | ||
| + | * Se prelucreaza rezultatul (intors sub forma de JSON) si se inregistreaza temperatura si umiditatea curente. | ||
| + | * In cazul in care conexiunea WiFi a fost intrerupta, se va incerca reconectarea. | ||
| + | * Datele inregistrate se trimit constant, actualizandu-se doar dupa intervalul de 10 minute. | ||
| + | === Arduino.ino === | ||
| - | + | * <code c++> printLCD(int temp, int humidity, int location) </code> | |
| - | + | * Scrie pe LCD datele primite ca argument (impreuna cu simboluri expresive). | |
| - | + | * <code c++> printDHT() </code> | |
| - | + | * Inregistreaza datele citite de catre senzorul DHT. | |
| - | + | * Apeleza functia //printLCD(int temp, int humidity, int location)// cu datele citite. | |
| - | + | * <code c++> printWiFi() </code> | |
| - | + | * Daca exista date disponibile pentru a fi citite, se vor inregistra, prelucra si afisa (asemenea DHT). | |
| + | * <code c++> setup(void) </code> | ||
| + | * Seteaza BAUD rate-ul. | ||
| + | * Initializeaza LCD-ul. | ||
| + | * Construieste simbolurile folosite in afisare. | ||
| + | * <code c++> loop() </code> | ||
| + | * Apeleaza functiile //printDHT()// si //printWiFi()// cu o pauza de 5 secunde intre ele. | ||

| ===== Concluzii ===== | ===== Concluzii ===== | ||
| + | * Proiectul poate deveni chiar folositor daca i se imbunatateste portabilitatea + folosirea unui cadru pentru piese. | ||
| + | * A fost interesant procesul de realizare a proiectului - de la alegerea pieselor la scrierea codului. | ||
| + | * Nu cred ca voi refolosi piesele utilizate. | ||
