8x8 LED Matrix Isticmaalka MAX7219 Arduino Module

Casharakan, waxaan baran doonaa sida loo xakameeyo matriiska LED-ka 8x8 adigoo isticmaalaya module MAX7219 oo leh Arduino. MAX7219 wuxuu fududeeyaa xakameynta LED-yada badan, taasoo noo oggolaaneysa inaan si sahlan u muujino xarfo iyo qaabab. Dhamaadka mashruucan, waxaad awoodi doontaa inaad ku muujiso erayga "ROBOJAX" matriiska.

Si aad tan u gaadho, waxaanu isticmaali doonaa maktabadda LedControl, oo si gaar ah loogu talagalay in lagu xiro MAX7219. Maktabaddan waxay noo ogolaaneysaa inaan xog u dirno matrix-ka LED-ka iyadoo aan dadaal badan gelin. Haddii aad rabto inaad si fiican u fahanto xargaha iyo koodhka, hubi inaad eegto fiidiyowga la xiriira (fiidiyowga 0:30).

Qalabka la Sharxay

Qaybaha ugu muhiimsan ee mashruucan waxaa ka mid ah module-ka MAX7219 iyo matrix-ka LED 8x8. MAX7219 waa wareeg isku dhafan oo maamula soo bandhigida LEDs, isagoo ka shaqeynaya isgaadhsiinta iyo calaamadaha xakameynta ee ka yimaada Arduino. Waxay isticmaashaa interface silsilad ah, taasoo la micno ah inaan ku xakameyn karno LEDs badan oo kaliya iyadoo la adeegsanayo dhowr pins oo ka socda Arduino.

8x8 LED matrix-ka wuxuu ka kooban yahay 64 LED oo gooni ah oo lagu habeeyey shabakad. LED kasta waxaa la shidi karaa ama la dami karaa iyadoo la dirayo amarada ku habboon iyada oo loo marayo MAX7219. Tani waxay u oggolaaneysaa in lagu soo bandhigo xarfo iyo sawirro kala duwan matrix-ka.

Faahfaahinta Warqadda Data

Soosaar	Maxim Integrated
Lambarka qaybta	MAX7219
Voltage-ka loogiga/IO	3.3V ilaa 5.5V
Koronto sahayada	4.0V ilaa 5.5V
Hawada hadda (kanaal kasta)	40 mA ugu badnaan
Culayska ugu sarreeya (kanaal kasta)	100 mA ugu badnaan
Hagaha soo noqnoqoshada PWM	100 Hz
Xadka loogaga talagalay gelinta	2.0V (sare) / 0.8V (hoose)

Hubi in koronto sax ah la helo (4.0V ilaa 5.5V).
Isticmaal iska caabinta xadka hadda ee LED kasta si aad uga hortagto waxyeello.
Xidhiidhka gaaban ku hay si aad uga fogaato faragelinta.
Kormeere kulaylka; isticmaal heatsink haddii loo baahdo.
Laba laba hubi xiriirada pin si aad uga fogaato isgaarsiin khaldan.

Tilmaamaha Xadhigga

Si aad u xidhid MAX7219 Arduino, ku xidh pins-yada soo socda:

XidhiidhiyahaVCCpin-ka MAX7219 ee 5V Arduino.
XidhiidhiyahaGNDku xirnaansho dhulka Arduino.
XidhiidhiyahaDINpin (Xogta Gudub) ku Arduino pin 12.
XidhiidhiyahaCLKkuus (Saac) kuus Arduino kuus 11.
XidhiidhiyahaCSpin (Xulashada Chip) ilaa pin Arduino 10.

Hubi inaad hubiso in dhammaan xiriiradu ay ammaan yihiin ka hor inta aanad korontada shidmin wareegga. Wayaheeda waa sahlan tahay, laakiin haddii aad la kulanto dhibaatooyin, dib u eeg xiriiradaha si taxadar leh (fiidiyowga 1:45).

Tusaalooyinka Koodhka & Socodka

Koodhka, waxaan ku bilaabaynaa inaan ku darno maktabadda LedControl, taasoo muhiim u ah isgaarsiinta la MAX7219. Qaybta soo socota waxay dejinaysaa shayga LedControl:

LedControl lc=LedControl(12,11,10,1);

Kani waa xariiqda dejinaysa pin-ka xogta, pin-ka saacadda, pin-ka doorashada chip-ka, iyo tirada qalabka (1, kiiskan). Kadib, gudahasetup()hawl, waxaan toosinaa MAX7219 oo aan dejinaa iftiinka muujinta:

lc.shutdown(0,false);
lc.setIntensity(0,8);
lc.clearDisplay(0);

Tani waxay xaqiijineysaa in shaashadu ay firfircoon tahay oo diyaar u tahay inay muujiso xarfo. Hawsha ugu weyn ee kaxeeya shaashadda waawriteArduinoOnMatrix(), taasoo si tartiib ah u iftiimisa safafka matrix-ka si uu u muujiyo xarfaha.

Muuqaal / Waxa La Filayo

Marka wax walba la isku xiro oo koodhka la soo geliyo, matriiska LED-ka waa inuu muujiyo erayga "ROBOJAX". Haddii muujinta aysan shaqayn, hubi dhibaatooyinka sida xiriir la'aan ama qodobbada khaldan. Sidoo kale, xaqiiji in korontada ay ku filan tahay (fiidiyowga 2:30).
