| - | * [[Fire]] | + | ===== Software Design ===== |
| - | * [[Rezistente]] | + | |
| + | Am utilizat Arduino IDE configurat pentru placa WEMOS(D1 R2 & mini) si urmatoarele biblioteci: | ||
| + | * ESP8266WiFi.h (Conexiune wi-fi locala) | ||
| + | * MD_Parola.h (Afisare text cu efect de derulare spre stanga) | ||
| + | * MD_MAX72xx.h (Configurare display matrice) | ||
| + | * SPI.h (Conexiune fire software) | ||
| + | * ESP8266HTTPClient.h (Client rest api) | ||
| + | * ArduinoJson.h (Pentru parsarea raspunsurilor venite de la coingecko) | ||
| + | * NTPClient.h (Ora din server) | ||
| + | * WiFiUdp.h (Ora din server) | ||
| + | * sstream (parsare input server/seriala) | ||
| + | * string (lucru mai usor cu siruri) | ||
| + | * unordered_map (legaturi simbol - id si simbol - nume ex: LUNA - terra-luna si LUNA - Terra) | ||
| + | |||
| + | ==== Mod de utilizare ==== | ||
| + | - Se asteapta afisarea ip-ului local. | ||
| + | - Se conecteaza folosind orice browser (desktop/mobil). | ||
| + | - Se introduc simbolurile pentru monedele dorite, separate prin virgula. (ex: bitcoin,ripple,terra-luna) | ||
| + | - Se selecteaza modul de afisare, directia de derulare si viteza de derulare. | ||
| + | - Se trimit datele catre client. | ||
| + | - Se profita. | ||
| + | |||
| + | ===== Rezultate obtinute ===== | ||
| + | Am obtinut un companion de nadejde. Practic, nu mai trebuie sa deschid 5 pagini diferite pentru toate monedele de care sunt interesat.\\ | ||
| + | Placuta + display-ul fac fix ce mi-am propus: aduna date dintr-un API extern la fiecare 5 minute si le afiseaza intr-un mod usor observabil.\\ | ||

| + | ===== Jurnal ===== | ||
| + | * 20.05.2022: Sosire piese. ~12 ore de cautat biblioteci functionale + schimbare/interschimbare fire. | ||
| + | * 22.05.2022: Realizare: legatura CS-SS trebuia facuta prin pinul D10, dar notata in cod cu D8. | ||
| + | * 23.05.2022: Creare server local. | ||
| + | * 25.05.2022: Conectare la un api gratuit + comunicare placuta - browser; browser - placuta. | ||
| + | * 26.05.2022: Rezolvare bug-uri (apelare millis() in loop produce "Soft WDT reset") + Finalizare proiect. | ||
