Cam asa as vrea... Se poate observa ca, daca lcd-ul se intoarce cu fata in sus configuratia se pastreaza. quartz-ul e de 10 mhz.de aici l-am luat...poate imi mai dai cv indicatii...ms.http://www.ebay.com/itm/170633064850?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2648#ht_1183wt_952

Stati sa inteleg: dvoastra vreti sa alimentati din pinul microcontrolerului?Parca un pin tine 25mA.Sa nu ardeti controlerul.......

[Drk_alien]

Incercati totusi sa imi faceti un demo.Nu cred ca se va arde nimik...dar totusi nu voi conecta vcc si gnd la iesirea microcontrolerului.

[Drk_alien]

Am reusit sa fac un cod care sa mearga cat de cat si sa vad ca se aprinda ori toti pixelii ori niciunul ori cate o linie... dar nimik perfect controlabil pt ca nu inteleg functia care imi scrie memoria lcd-ului.

Ma poate ajuta cineva sa imi corecteze codul ca sa imi afiseze un cuvant pe ecran?...si sa imi explice ce se intampla in LCD_write_byte() ca sa stiu sa manipulez singur functia pe viitor.Va multumesc tare mult.

for(i=0;i<8;i++) { if(dt&0x80) sdin=1; else sdin=0; dt=dt<<=1; sclk=0; sclk=1; }}[/code]

La cod cred ca te pot ajuta eu putin, la restul nu.Banui ca probleme la intelegere iti ridica bucla for din functie.In bucla asta e testat fiecare bit din byte-ul de date (dt) incepand cu MSBit (bitul cel mai semnificativ, cel din stanga. Notatia standard pentru bitii unui byte e b7b6b5b4b3b2b1b0, MSB e b7).Operatia dt&0x80 este un SI logic intre byte-ul de date si b'10000000'; rezultatul operatiei e diferit de 0 (b'1000 0000) daca b7 = 1 si 0 daca b7 = 0. Asta testeaza si if-ul din bucla si face iesirea (sdin) 1 sau 0 in functie de valoarea lui b7. dt = dt<<=1; e gresit, ar trebui sa fie dt = dt<<1; este operatie de deplasare stanga si nu face altceva decat sa mute cu o pozitie (numarul de dupa << indica numarul de pozitii de deplasat) la stanga fiecare bit din dt. b7 se pierde, b6 devine b7, b5->b6... In felul asta se pot testa cu aceeasi operatie (dt&0x80) si ceilalti biti ai dt, pana se termina (8 cicluri ale lui for).scl0/scl1 genereaza clockul necesar comunicatiei.

[Drk_alien]

Chia daca iti vine sa crezi sau nu, dt=dt<<1 sau dt=dt<<=1 face la fel.nu primesc eroare iar codul rulat in ambele conditii ruleaza la fel.pe mine m-ar interesa mai mult cum as putea sa controlez mai precis pixelii lcd-ului.de ex daca vreau sa afisez caracterul "a" pe toata suprafata cred ca se face un array []={ 0x1f,0xca,....} si apoi se merge la coordonata dorita si cu functia lcd_ write se scrie.dar cum modific codul meu pt a face asta?

[godFather89]

Chia daca iti vine sa crezi sau nu, dt=dt<<1 sau dt=dt<<=1 face la fel.nu primesc eroare iar codul rulat in ambele conditii ruleaza la fel.

dt = dt << 1; este echivalent cu dt <<= 1;dt = dt <<= 1; contine inca o atribuire. practic face dt<<=1 (dt = dt << 1) si apoi atribuie valoarea (din nou) lui dt. Probabil compilatorul isi da seama ca e degeaba si lasa doar dt <<= 1.

pe mine m-ar interesa mai mult cum as putea sa controlez mai precis pixelii lcd-ului.de ex daca vreau sa afisez caracterul "a" pe toata suprafata cred ca se face un array []={ 0x1f,0xca,....} si apoi se merge la coordonata dorita si cu functia lcd_ write se scrie.dar cum modific codul meu pt a face asta?

LCD_set_XY(0,0);LCD_write_byte(0x1F, 1);LCD_write_byte(0xCA, 1);...deoarece este un lcd grafic, ai nevoie de un font.

[Liviu M]

Pe la inceputul topicului lama a pus un proiect cu lcd-ul asta. In fisierul 5110.c are un vector in care sunt "definite" caracterele ascii. Daca vrei o imagine personalizata trebuie s-o creezi din "bucatele" de dimensiunea unui caracter (din cate stiu eu, desi grafice displayurile astea tot cu "caractere" lucreaza), bucatele pe care ti le definesti dupa nevoi.

[godFather89]

Nu, sunt chiar grafice. Problema e ca trebuie sa trimiti datele a 8 pixeli (pe coloana) deodata.

Uite aici un driver scris de ceva vreme pentru un display de nokia 3410. Poti desena imagini, patrate, text si pixeli. Este in C++ si l-am folosit pe un xmega, dar cu putine modificari merge pe orice.

[Drk_alien]

Nu cred ca e bun ecranul.Daca il misc imaginea joaca , pixelii au diferite contraste...adica imaginea nu e stabila deloc.cand il ating unii pixeli se aprind apoi dispar...habar nu am :-?? .Codul e bun.Cred ca am sa cumpar altul. Are cineva de vanzare de pe aici? Chiar nu am chef sa comand altul din china si sa ajunga peste 2 luni.

[Liviu M]

Masa displayului e conectata sigur bine?

[Drk_alien]

Bun.......... .Am mai comandat inca un ecran, dupa ce l-am montat se comporta la fel ca cel pe care il credeam ca e busit .Am incercat sa scriu tot felul de caractere ca sa testez ecranul dar fara mari reusite.Am incercat sa afisez si niste imagini generate de un program.Ori imi afiseaza tot ecranul plin, ori pe jumatate....Se incapataneaza cineva sa ma ajute sa ii dau de cap?...ps: conexiunile sunt bine facute.

[Drk_alien]

Dupa ce am primit si cel de-al doilea ecran m-am gandit ca e posibil ca eu sa nu fac ceva bine, m-am pus pe verificat cod si consultat cu alte tutoriale

Dupa vreo 2 ore in care am transpirat de numa am reusit sa fac urmatorul cod care sa mearga:
