Afisajul folosit la telefoanele Nokia 5110/3310 si Arduino (IV)

   Fata de articolele anterioare, acum o sa prezint ce grafica interesanta se poate face folosind libraria GFX de la Adafruit pentru afisajele folosite la telefoanele Nokia 5110 sau 3310, care sunt controlate de driverul PCD8544, iar rezolutia grafica este de 84x48 pixeli.
   Schema de conectare, inclusiv adaptorul de tensiuni e acelasi:
   M-am gandit la un secundar de ceas...
iar porecla de pe net (niq_ro) sa fie afisat in partea de jos cand secundarul este in zona de sus, respectiv in partea de sus cand secundarul este in partea de jos:
   Pentru a desena ceva, trebuie sa stim ca dimensiunea utila este de 84 de puncte pe orizontala si 48 pe verticala, punctul notat cu (0,0) este in coltul din stanga sus, iar cel cu (83, 47) este in dreapta jos.
   In libraria grafica Adafruit_GFX, comanda pentru linie, este:
 display.drawLine(x0,y0, x1, y1, BLACK);  
   (x0,y0) sunt coordonatele punctului de inceput, iar (x1,y1) sunt coordonatele punctului de final al liniei.
   Pentru a desena un cerc, comanda este urmatoarea:
 display.drawCircle(x0, y0, r, BLACK);  
   (x0,y0) sunt coordonatele centrului cercului, iar r este raza cercului.
   Un prim filmulet, realizat cu un telefon Samsung, se numeste Adafruit GFX library + Nokia 5110 LCD + niq_ro's sketch (I):
ulterior am incercat si cu un telefon Nokia Asha 201, rezolutia fiind mult mai proasta... filmuletul se numeste Adafruit GFX library + Nokia 5110 LCD + niq_ro's sketch (II)
   Am folosit si un aparat foto FujiFilm S5700, filmuletul numindu-se Adafruit GFX library + Nokia 5110 LCD + niq_ro's sketch (III)
   Sketch-ul scris de mine, care "face" ce se vede in cele 3 filmulete este urmatorul:

    Filmuletul ce prezinta ce am scris mai sus se numeste Adafruit GFX library + Nokia 5110 LCD + niq_ro's sketch (IV)


    Aceasta grafica se poate folosi sa se afiseze un ceas analog cu date citite de pe un ceas de timp real (RTC) cu DS1307, de exemplu...

15.01.2014
   Deoarece intre timp afisajul a "decedat" din cauza contactului elastic prost intre cablaj si ecran, am achizitionat altul si l-am testat cu acest sketch, facand si filmuletul graphic test with my new Nokia 5110 LCD module

2 comentarii:

  1. se poate folosi arduino nano fara a fi modificat nimic pentru testarea unor lcd de nokia 5110 cu LPH7366
