Salutare.Am acest afisor la care am incercat mai multe exemple.Am reusit sa il comand cu codul de aici:

Intrebarea mea este cum imi pot da seama ce librarie foloseste?

May 29, 2017

La cum arata, nu foloseste nici o biblioteca, si-a scris singur toate functiile care-i trebuie.

May 29, 2017

Am reusit sub forma aceasta:

U8GLIB_KS0108_128 u8g(2, 3, 4, 5, 6, 7, 8, 9, A5, 11, 12, A3, A4); // 8Bit Com: D0..D7: 8,9,10,11,4,5,6,7 en=5, cs1=11, cs2=12,di=A3,rw=4

Dupa cum am citit cred ca este functionare pe 8 biti si libraria de la KS0108

pe ultimul link scrie, când vorbeşte de ecran:

Any LCD that has a resolution of 128 x 64 and that is "compatible with KS0108" will do. You may choose negative LCDs as well.

deloc de mirare că a mers cu u8glib, care "ştie" deja cum să comande un ecran cu chipset KS0108 sau echivalent...

Acesta este codul.

Vreu sa implementez un ceas si un senzor presiune sau umiditate.Incerc sa vad acum,pornind de la alte exemple.

May 31, 2017

Am reusit sub forma aceasta:

U8GLIB_KS0108_128 u8g(2, 3, 4, 5, 6, 7, 8, 9, A5, 11, 12, A3, A4); // 8Bit Com: D0..D7: 8,9,10,11,4,5,6,7 en=5, cs1=11, cs2=12,di=A3,rw=4

Dupa cum am citit cred ca este functionare pe 8 biti si libraria de la KS0108

Ca sa am pini liberi la arduino uno,acest afisor se poate comanda si altfel decit am trecut mai sus?

May 31, 2017

Da, insa este un pic mai complicat. Trebuie sa folosesti C.I. MCP23017(018) sau MCP 23S17(18), ambele expandere pe 16 biti, porturi bidirectionale cu comanda I2C sau SPI (cele care au litera S).

Mersi,am vazut un tutorial cu asa ceva. Am sa incerc sa mut iesirile de pe A4 si A5 .Un DS3231 incerc sa implementez.

June 2, 2017

Salutare.revin din nou cu o intrebare.Am implementat un DS1307 si imi afiseaza.Mi-a ramas pini liberi la Arduino Uno ,pinii 0 , 1 ,10.Vreau sa fac sectiunea de reglare a minutelor,orei,zi luna,an. Se poate face sub forma de meniu?adica asa cum sunt pe LCDkey schield:

https://www.dfrobot.com/wiki/images/a/a7/LCDKeypad_Shield_SCH.png

si configurarea ca aici?

https://www.dfrobot.com/wiki/index.php/Arduino_LCD_KeyPad_Shield_(SKU:_DFR0009)

sau este diferit pentru librariile U8GLIB,in acest format:

https://codebender.cc/example/U8glib/Menu#Menu.ino

sau poate care este mai avansat poate da un sfat mai simplu

Va multumesc.

Dar nu imi dau seama ce mai am nevoie sa pot comuta.

Ca sectiune de butoane vreau sa fie asa:

m-am uitat pe linkul de pe forumul dfrobot, apoi pe codul pus de tine... îmi pare că ai copiat pur şi simplu codul scris de Steve ăla... iar din unicul reply, se pare că tipul a încălcat oareşce reguli de adresare a u8glib... altfel nu era trimis să recitească user manualul...

ai mai folosit push-butoane cu Arduino? au mers exemplele, ai înţeles cum se face?
modul de adresare a unui şir de butoane pe un singur fir l-ai înţeles (din ultima schemă pare că asta vrei să faci, şi e o soluţie demult cunoscută şi folosită), ai reuşit să deplasezi cursorul unui afişor 16x2 folosind aşa ceva? (adresarea unui 16x2 e deja trivială, nu ar trebui să ai probleme în a deplasa cursorul şi în a crea meniuri scrollabile).

în fine, există un avertisment în legătură cu u8glib: haleşte aproape tot flashul disponibil într-un 328, şi e foarte posibil ca pur şi simplu să nu mai ai loc.

am de gând să trec şi prin exemplele de tipul ăsta în curând, şi, deocamdată, nu reuşesc să-mi dau seama exact din codul ăla care e secţiunea care se ocupă de butoane, cum sunt definite, cum se stabileşte modul de adresare, şi am sentimentul că exact asta e problema pe care o ai.

(nu te încânta prea tare că la compilare nu primeşti nici un fel de eroare... mi s-a întâmplat şi mie, şi multor altora, să compilez fără erori, dar codul să se comporte altfel decât voiam eu, sau să nu "mişte" deloc... compilatorul se uită doar dacă e codul corect din punct de vedere al sintaxei şi directivelor include, nu se chinuie să ghicească ce vrei tu să obţii, de fapt, şi să îţi spună cum să obţii aia...)

Acel cod am vrut sa-l adaptez la un ceas grafic.Defapt am trei modele dar nu reusesc sa implementez butoane.Deaceea am postat in speranta ca poate careva a mai folost acest cod.Si daca este ompatibil cu libraria mea u8glib
