ceas cu lcd 16x2

[bogdan546]

Am realizat acest proiect si l-am modificat un pic, dar as fi dorit sa pot fixa alarma fara sa fiu nevoit sa trec prin toate setarile( salvarea in memorie se face la final)   Pentru a testa mai multe variante am simulat in proteus  si am atasat mai jos simularea . As fi recunoscator daca ma poate ajuta cineva .

Dacă puneai și hexu poate puteam simula măcar de curiozitate. Pe de altă parte de ce te deranjează că ai ceva de defilat prin meniu până la reglarea alarmei? Bănuiesc că nu o setezi zilnic la ore diferite. Având fizic 4 butoane, parcă atâtea am văzut în proteus, îți poți regândi partea de reglaje cum vrei tu, inclusiv funcții noi la combinații neortodoxe  ale acelor butoane adică 2 apăsate simultan. 

[bogdan546]

Imi este utila setarea alarmei la inceput pentru ca pana la reglarea alarmei ceasul este oprit. Adica incepe sa functioneze abia dupa ce sunt salvate setarile

Acesta este hex-ul

Ca sa setezi alarma inainte de timp, cred ca e suficient sa schimbi ordinea if-urilor (apelezi setAlarmTime() la if(btnCount==1) si pentru timp folosesti btnCount == 2..7), dar salvarea in EEPROM tot la sfarsit va fi, dupa ce ai parcurs tot meniul.

Pe de alta parte, chiar functioneaza setarea minutelor pentru alarma? Ca mie mi se pare ca n-ar trebui.

Pe de o parte ai

    if(btnCount<7){
      btnCount++;
...
    } 
    else{
...
      btnCount=0;

adica btnCount ia valori in intervalul 0 .. 6, pe de alta parte ai:

  else if (btnCount==7){        //Set alarm Minutes

care n-ar trebui sa fie niciodata adevarat.

[bogdan546]

Imi este utila setarea alarmei la inceput pentru ca pana la reglarea alarmei ceasul este oprit . Adica asa dori sa pot salva imediat dupa ce setez alarma .

[Liviu M]

Am inteles ce si de ce vrei, da' mi se pare complicat, practic trebuie schimbata complet structura programului...

Oricum, mai sus am gresit, la setat alarma ai nevoie de doua valori pentru btnCount, asa ca potrivit ceasul va incepe de la 3. Sau de la 4 daca folosesti 3 pentru salvat alarmele.
