Am gasit, hexul nu este bun, am cautat pe net si am gasit un proiect care avea pini lcd-ului legati in acelasi mod cu acest LCF, am scris codul si functioneaza ok...

Uitati linku de unde am luat hexul.: http://radiohobbystore.com/mikrobasic-pic16f628a-free-text-lcd-hd44780

Cine are un sa imi dea si mie hexul pentru pic16f628A? ced de pe site la-m incarcat de multe ori si degeaba...

[Vizitator luxornet]

costyy86Ce cuart ai folosit? ai avut de 3.2768MHz ? poate ai folosit de 32KHz, luat din ceasuri.

[costyy86]

Am folosit de 4Mhz, nu am altu, dar am vazut aici ca au mai pus si fuctioneaza...

Copiezi textul din dreptul ":" cu tot cu ":" si il bagi intr-un fisier. Il pun asa ca sa nu se stearga pe viitor.

Cine are un sa imi dea si mie hexul pentru pic16f628A? ced de pe site la-m incarcat de multe ori si degeaba...

Multumesc, dar adevarata problema cred ca este quartul, ca nu am de acea valoare, decat de 4desi am vazut aici ca a incercat un user si functiona , dar nu stiu cat de precis era, totusi incerc sa vad..

[nel65]

^uite si varianta cu cristal de 4 mhz http://elforum.info/viewtopic.php?f=205&t=97938 iei hexul de acolo

Tot asa face, nu stiu care e problema, dar ce ma supara mai mult e faptul cavdaca bag alt soft in el functioneaza ok...

[costyy86]

Voi cu ce ati programat picul? cu ce program? a trebuit facute unele setari???poate nu il programez eu corect...

[pinky]

Eu folosesc "PIC PGM Programmer" cu JDM. Am tot avut probleme cu WinPIC800. Setarile sunt incluse in fisierul hex, nu ai nimic de setat la configuratia PIC-ului.Pentru simulari folosesc "PIC Simulator IDE". Are numar limitat de simulari dar e free. Eu l-am instalat pe un Windows curat iar cand expira programul, reinstalez Windows-ul si o iau de la zero cu simularile.

"Afisajele LCD cu controler HD44780 TREBUIE initializate", am citi pe net...mai mult nu am gasit...ce vrea sa insemne asta?

[DREDD]

"Afisajele LCD cu controler HD44780 TREBUIE initializate", am citi pe net...mai mult nu am gasit...ce vrea sa insemne asta?

Initializarea e facuta de catre microcontrolerul care le comanda, prin instructiuni specifice - a nu se confunda cu programarea lor directa.

[costyy86]

Am reusit sa fac LCF-ul sa functioneze, se pare ca in schema psa de autor ewsra o greseala la semireglabilul care modifica contrastul, doi pini erau legati la GNd desi unul singur trebuialegat la GND unul la lcd si unul la 5v, dar problema este ca nu functioneaza inductanta..imi spune "WAITIN TIMING" si are 0Hz, si daca pun bornele in scut tot asa ramane, si daca dau pe set tot nu se schimba nimic...oare ce sa fie?Capacitori masoara dar imi da valori cu 25% mai mari la oricare capacitor...

[nel65]

verifica piesele ,traseele,lipiturile,si poti sa incepi cu bobina de pe cablaj,parca de 10 uH,sa nu fie intrerupta

[costyy86]

Multumesc, bobina de 10uH nu era lipita bine, am reusit am calibrat totul, si am masurat condensatori de 4700uf si este ok, insa cand am masurat un condensator de 5000Uf cred ca era defect ca mi-a blocat LCF-ul a ramas blocat nu mai misca nimic pana nu la-m repornit, si acum desi am reprogramat picul nu mai vrea sa imi scada inductana sub 14uH, cu semirelabilu la minim si tot nu scade, si inainte scadea...am schimbat si picul si HFE-ul si tot asa face, de urcat urca foarte mult dar de scazut nu vrea...am pus si un condensator de 30pf intre piul 5 si 7, dar nici un efect....mentionez ca toti condensatori masurati ia-m descarcatinainte...

LCF-ul facut de tine nu se simte bine la masurarea condensatorilor cu valori peste 1000 uF. Pentru masurarea electroliticilor iti recomand sa-ti construiesti alt aparat prezentat aici: viewtopic.php?f=290&t=80189Daca nu-ti functioneaza din prima, nu te impacienta. Cauta trasee intrerupte sau in scurt. Schema si hex-ul sunt verificate, ca fiind perfect functionale, de foarte multi utilizatori.LCF-ul facut de tine este perfect pentru masurat inductante si condensatori cu valori sub 100 uF. Inainte de a-l baga intr-o cutie, asigura-te ca nu are "fuga" de frecventa. Pe linia de sus iti arata frecventa la care se face masuratoarea. Cu testerele in aer, acea frecventa trebuie sa fie cat mai stabila. Frecventa afisata are voie sa se modifice daca pui mainile pe testere dar sa se stabilizeze sau macar sa se modifice foarte putin.
