 ===== Descriere generală =====
-O grupare de matrice LED pe care se vor afisa preturile celor mai importante 10 criptomonede de pe piata,
+O grupare de matrice LED pe care se vor afisa preturile unor monede primite ca input intr-un server hostat pe placuta.\\
-conform [[https://coinmarketcap.com/|coinmarketcap]].
 Datele vor fi culese prin cereri http catre un API extern, folosind modulul ESP8266 pentru conexiunea la internet.

+===== Software Design =====
+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.
