In ai multe proiecte am folosit metoda multiplexarii, care pentru anumite persoane e ceva ciudat si de neinteles, asa ca o sa incerc sa va prezint aceasta metoda, cum am folosit-o eu la ceasuri sau la termostatele cu afisaj led din 7 segmente.
Metoda este folosita de foarte mult timp, in primul rand, pentru ca reduce mult namarul de pini ai afisajului: la afisajul multiplexat cu 4 cifre sunt doar 12 pini (4 cifre si 8 segmente), pe cand la un afisaj cu comanda separata sunt folositi 28 pini (4 grupe de cate 8 segmente).
Daca vreau sa afisez ora 12:34, sunt 2 cazuri:
- cu secundele aprinse (in cazul de fata, doar punctul zecimal de la cifra a 2-a)
- fara secunde
Bun, acum, pentru cazul afisarii orei cu secunda:
respectiv fara secunda
deci sunt 4 timpi:
- primul timp: se alimenteaza prima afisaj si se aprinde cifra 1
- al doilea timp: se alimenteaza al doilea afisaj si se aprinde cifra 2 ( cu sau fara punctul zecimal)
- al treilea timp: se alimenteaza al treilea afisaj si se aprinde cifra 3
- al patrulea timp: se alimenteaza al patrulea afisaj si se aprinde cifra 4
apoi se repeta de la timpul 1.
La afisajele cu anod comun, un fisaj se comanda prin alimentarea cu plus a pinului comun si conectarea minusului, cel putin printr-o rezistenta de limitare a curentului, la toate segmentele dorite a se aprinde, iar la afisajul cu catod comun, segmentele seconecteaza la plus prin rezistenta si la masa se conecteaza pinul comun. Cifrele si anumite litere sau simboluri se fac cum e prezentat in articolul 7-segment HEX decoder
In articolul precedent am folosit pentru partea ceas propriu-zis (ore si minute) informatiile oferite de un ceas de timp real cu DS1307, acum o sa folosesc libraria Time.h care se bazeaza pe functia millis(), care numara milisecundele de la alimentarea placii Arduino. Intr-un articol numit 12.4Using Arduino as a Clock sunt date si exemple de programele (sketch-uri) inclusiv un exemplu de crestere, respectiv scadere a minutelor, dar eu l-am adaptat sa modific orele si minutele, in sens crescator. Un ceas, care foloseste ceasul intern al lui Arduino si senzorul DHT11 pentru temperatura si umiditate, se comporta similar cu cel prezentat in articolul anterior, vedeti filmuletul humidity and temperature with DHT11 using 7-segment LED from a broken wood brick clock (IX)
Pentru prima varianta, schema este cea folosita si anterior:

/* 6-13-2011 Spark Fun Electronics 2011 Nathan Seidle This code is public domain but you buy me a beer if you use this and we meet someday (Beerware license). 4 digit 7 segment display: http://www.sparkfun.com/products/9483 Datasheet: http://www.sparkfun.com/datasheets/Components/LED/7-Segment/YSD-439AR6B-35.pdf This is an example of how to drive a 7 segment LED display from an ATmega without the use of current limiting resistors. This technique is very common but requires some knowledge of electronics - you do run the risk of dumping too much current through the segments and burning out parts of the display. If you use the stock code you should be ok, but be careful editing the brightness values. This code should work with all colors (red, blue, yellow, green) but the brightness will vary from one color to the next because the forward voltage drop of each color is different. This code was written and calibrated for the red color. This code will work with most Arduinos but you may want to re-route some of the pins. 7 segments 4 digits 1 colon = 12 pins required for full control */// modified connexion by niq_ro from http://nicuflorica.blogspot.com// for my Luckylight KW4-563ASA// dataseet: http://www.tme.eu/ro/Document/dfc2efde2e22005fd28615e298ea2655/KW4-563XSA.pdfint digit1 = 11; //PWM Display pin 12 (digit1 is common anonds A1 from right side)int digit2 = 10; //PWM Display pin 9 (digit2 is common A2)int digit3 = 9; //PWM Display pin 8 (digit3 is common anods A3)int digit4 = 6; //PWM Display pin 6 (digit4 is common anods, from left side)//Pin mapping from Arduino to the ATmega DIP28 if you need it//http://www.arduino.cc/en/Hacking/PinMappingint segA = 2; //Display pin 11int segB = 3; //Display pin 7int segC = 4; //Display pin 4int segD = 5; //Display pin 2int segE = 12; //Display pin 1int segF = 7; //Display pin 10int segG = 8; //Display pin 5int segDP = 13; // Display pin 3
