Ceas cu display LED 8x8 dot matrix si modul DS3231

Recommended Posts

Voi incerca, multumesc.

Butonul de alarma trebuie pe pinul 1 (PORTA 2), nu pe pinul 2 (PORTA 3).

 

...am setat 'C : 01, dar tot nu pot scapa de "bucla".

Oare functionarea defectuoasa are legatura cu faptul ca :

- la PIC16F1824 INT/T0CKI este acelasi pin, 11 (RA2) - conectat la SQW

- la PIC16F1827 INT este pinul 6 (RB0) - conectat la SQW, iar T0CKI este pinul 3 (RA4) - buton Mode ?

Salutare tuturor!

Ieri, am dat si eu peste matricile mele led, au 7x5 leduri si am 4 placi cu cate 10 bucati fiecare, plus placa de comanda pt ele. Matricile nu au porpria lor placa cu acel driver, insa sunt infipte toate 10 pe o placa ce contine mai mlte integrate smd, probabil driverele. Intrebarea mea este daca s-ar putea face un ceas cu ce am eu, Poze cu placile aici https://imgur.com/a/QtU6jyc iar datasheetul matricilor aici https://www.datasheets360.com/pdf/-924877231404308062. Multumesc pentru orice ajutor!

Da, folosind DOAR matricele cu led-uri. Si eventual alte componente marunte. In rest, ai 3 controllere acolo (din care unul este M30264, celelalte doua sunt ilizibile ca marcaj) si posibil ULN 2004 sau ceva similar pentru actionarea matricelor.
