Ceas cu display LED 8x8 dot matrix si modul DS3231

[Kreator]

Cum modulele electronice de pe eBay au devenit tot mai ieftine se poate realiza cu acestea un ceas interesant, frumos si util, costul realizarii fiind modic.

Aici se poate vedea un video despre ce poate ceasul sa faca.

Mai multe detalii  despre realizarea acestui ceas gasiti AICI, unde este explicat in detaliu modul de functionare a ceasului.

 

 

Astea fiind spuse, hai sa vedem cum facem ceasul. Schema electrica este urmatoarea.

 

Dintre particularitatile acestui ceas amintesc:
- afisarea orei si temperaturii, tranzitia acestora facandu-se prin efect de scroll;
- formatul orei este 0-24;
- punctul din fata orei indica daca alarma este on/off;
- folosirea a 4 butoane:  up, down, mod si alarma;
- butonul mod selecteaza ce se afiseaza;
- cu butoanele up si down se modifica ceea ce este afisat;
- butonul alarma are doua functii: seteaza modul on/off al alarmei (si-l afiseaza pe display prin pct-ul dinaintea orelor) si opreste soneria atunci cand aceasta suna.
- ceasul are doua moduri de afisare: doar a orei sau ora si temperatura selectabile din meniu prin setarea parametrului " ºC ";
- reglarea intensitatii luminoase in 16 trepte prin setarea parametrului " Br ";
- memorarea starii alarmei, a intensitatii luminoase si a modului de afisare, acestea nefiind afectate de interuperea alimentarii.

 

Hex-ul necesar este urmatorul  Ceas_MAX7219_PIC1824.hex

Pentru cei ce vor sa adauge functionalitati noi sau sa foloseasca alt tip de PIC, progamul necesar facut in mikroBasic este:

Arată bine ceasul, îmi plac caracterele îngroșate și scrolul. Cum ți s-a părut precizia pe partea de temperatură ? M-am jucat și eu cu acel rtc dar am folosit ca senzor un DHT11 și 22 în ideea de a avea și umiditate, dar e un avantaj al DS3231 că oferă și informație termică.

Si mie imi plac caracterele "bold"-uite!  Mi-a luat ceva timp pana le-am creat asa cum imi plac mie adica sa dea bine atat de aproape cat si de la distanta fiindca ceasul va sta outdoor pe terasa de vara.

Precizia temperaturii depinde de locul unde e montat modulul DS3231. Daca este in interiorul carcasei ceasului, acesta indica (la mine) cam cu 3 - 5 grade Celsius in plus. Asta deoarece afisajul si regulatorul de tensiune genereaza caldura si incalzeste interiorul carcasei. Daca modulul RTC se monteaza pe exteriorul carcasei ai sa fie in contact cu aerul din mediul ambiant atunci precizia este buna.

Va rog sa ma ajutati cu programarea acestui microcontroler cu pickit2 deoarece programatorul nu-l detecteaza si in lista pt. selectare manuala nu exista.

Multumesc!

Pai Pickit2 nu-l are in lista de controllere "suportate".

 

http://ww1.microchip.com/downloads/en/devicedoc/pickit 2 readme v2-61-00 (a).txt

 

Daca nu aveti Pickit3, va ramane sa adaptati codul altui controller.

 adaptarea trebuie facuta in softul programatorului sau si in controller?

Daca nu rezolvi iti trimit io un 1824 THT gata scris, daca-ti platesti curieru` si postezi o poza cu ceasu` cand ii gata... am amintiri placute cu Slobozia...   

[minel]

De acord.

As fi vrut totusi sa vad cum l-as putea scrie cu pickit2 asa cum a relatat autorul pe alt site.

Multumesc!

Am inteles,am sa caut update-ul.

cred ca pe asta il am eu

[minel]

Mersi,ramane sa vad cum il integrez in pickit2!

redenumesti vechiul fisier din directorul de instalare (ca sa-l ai backup in caz ca ceva nu merge) si dezarhivezi zip-ul in acel director.
