Ceas RGB WIFI

[Kreator]

Daca tot am avut ceva timp liber de sarbatorile pascale, am facut un upgrade la ceasul de aici , in sensul ca display-ul este un panel RGB cu WS2812B  ca acesta comandat de un Wemos D1 mini. Schema e mai jos (desenata cum e moda acum )

Culoarea si intensitatea luminoasa a display-ului se schimba prin cele 4 slidere, iar ora si minutul prin modificarea casetelor corespunzatoare. Prin combinatia celor trei slidere care comanda culorile se obtine o paleta cromatica destul de variata.

Tranzitia de la ora la temperatura si invers se face prin efect de scroll.

Valorile corespunzatoare culorilor RGB si intensitatii luminoase sunt salvate in memoria AT24C32 si incarcate automat la pornire.

 

 

 

Sketch-ul folosit e urmatorul, nu dati cu parul daca nu e optimizat si uneori e redundant, nu sunt programator, nici macar cu studii de electronica dar orice observatii constructive sunt binevenite.

Doritorii pot modifica Sketch-ul asfel incat culorile sa se schimbe automat, efect de curcubeu, sau alte efecte dorite.

Felicitari! Interesant proiect!

Foarte tare bravo, nu știam de acest tip de display.

[Mircea]

Cristi, creator de ceasuri... frumos si interesant! 

[Vizitator]

Frumos proiect.
Si mai frumos era daca nu continea "delay".
Nu stiu altii cum sunt, dar eu cand vad utilizata delay() am ceva de comentat.
Si , evident, se putea optimiza putin codul. Cred ca merge scris cu mai putin de 50% dintre liniile de cod de acum.

@tizu: știi că la esp8266 delay() e necesar din când în când, da? 

[Vizitator]

Delay() , ca metoda, trebuie evitata.
Timpi de intarziere sunt, normal, necesari uneori pentru anumite activitati.
Dar, ideal, se pot obtine cu timere.
Si Dumnezeu a facut o pauza dupa facerea lumii. Dar singur nu a stat degeaba in acest timp. S-a gandit EL la ceva ...
Ideea mea este ca in activitatea umana nu exista echivalent pentru "delay()". Nici macar somul nu este un delay profund.
De ce sa-l folosim in programare ?

Tu ai citit ce scrie in link-ul pus de @Liviu M?

 

Quote

Remember that there is a lot of code that needs to run on the chip besides the sketch when WiFi is connected. WiFi and TCP/IP libraries get a chance to handle any pending events each time the loop() function completes, OR when delay is called. If you have a loop somewhere in your sketch that takes a lot of time (>50ms) without calling delay, you might consider adding a call to delay function to keep the WiFi stack running smoothly.

There is also a yield() function which is equivalent to delay(0). The delayMicroseconds function, on the other hand, does not yield to other tasks, so using it for delays more than 20 milliseconds is not recommended.

 

 

P.S. @Liviu M am o curiozitate: esti si tu pescar?

Canci. O părare a unui Gigel (ca si mine) despre programare (ma refer la zicerile din link).
Dacă-l aude un Linus Benedict Torvalds sau (chiar si un) Gates Bill se cacă pe el de râs.
Daca delay() se utiliza prin sistemele de operare, telefoane sau routere ... aveam acces la net dupa o saptamana de la pornirea dispozitivului
Hai sa fim seriosi si sa nu mai credem toate căcaturile scrise pe post de "cele 10 porunci" pe net.

Scuze. Ma duc la "delay" acum. O seara buna.

Gigel ala s-a ocupat de integrat esp8266 in mediul Arduino. Parca l-as crede mai tare pe el decat pe tine. 

PS Nici linux, nici dos nu-s sisteme de operare in timp real, probabil n-au nevoie de delay() ca sa "piarda" timp.

Controleaza-ti vocabularul! Si inca ceva: aici nu vorbim despre sisteme de operare ci despre o aplicatie practica, folosind mediul Arduino care, intamplator sau nu, foloseste si delay() indiferent daca tie iti place sau nu, sau daca tu folosesti sau nu afeasta functie. Delay foloseste oricum un timer aşa că....

[Vizitator]

@nico_2010
Aplicatie practica (cu vocabular controlat) :
Softul de mai sus se poate adapta pentru a controla o drona folosind pagina web.
Vom adauga un senzor de proximitate pentru a evita ca drona sa se loveasca de obstacole.
Daca de fiecare data cand se pierde conexiunea wireless softul din drona tot face "delay", este foarte probabil sa o gasim lipita de un perete.
