Koodka Arduino si loo isticmaalo joystick-ka laba-dhidibeedka XY oo leh shaashadda Nokia 5110 LCD.

Tilmaantan waxay ku hagaysaa habka loo isticmaalo joystick-ka laba-dhidibka ah ee XY si loo xakameeyo dhibic lagu muujiyey shaashadda Nokia 5110 LCD. Mashruucu wuxuu ku lug leeyahay akhrinta booska joystick-ka iyo cusboonaysiinta shaashadda si waafaqsan. Markaad dhammayso tilmaantan, waxaad yeelan doontaa qaab shaqeeya halkaasoo dhaqaaqista joystick-ku ay beddesho booska dhibicda shaashadda (fiidiyowga 00:00).

Mashruucan, waxaad isticmaali doontaa wax soo saarka analog-ga ah ee joystick-ka si aad u go'aamiso booskiisa dhidibyada X iyo Y. Akhrinta joystick-ka waxaa loo qaabayn doonaa cabbirrada shaashadda LCD, taasoo u oggolaanaysa dhaqaaq siman oo dhibicda ah. Intaa waxaa dheer, waxaad baran doontaa sida loo akhriyo gelinta kala-beddelka joystick-ka, kaas oo loo isticmaali karo isdhexgal dheeri ah.

Qalabka La Sharaxay

Qaybaha aasaasiga ah ee mashruucan waxaa ka mid ah Arduino-ga, joystick-ka laba-dhidibka ah ee XY, iyo shaashadda Nokia 5110 LCD. Arduino-gu wuxuu u shaqeeyaa sida kontoroolka, isagoo farsameeya gelinta joystick-ka oo xakameeya shaashadda LCD.

Joystick-ku wuxuu caadi ahaan leeyahay laba potentiometer—mid X-dhidibka iyo mid Y-dhidibka. Markaad dhaqaajiso joystick-ka, potentiometer-yadani waxay beddelaan iska caabinta, iyagoo u soo dira heerar danab kala duwan oo ah gelinta analog-ga ee Arduino-ga. Shaashadda Nokia 5110 LCD waxaa lagu xakameeyaa isgaarsiinta SPI, taasoo u oggolaanaysa wareejinta xogta iyo cusboonaysiinta shaashadda si hufan.

Faahfaahinta Xogta

• Hubi inaad si fiican u qaboojiso kulaylka si shaqo joogto ah.
• Isticmaal capacitors-ka decoupling si sahayda korontadu u degganaato.
• Hubi qiimaynta danabka si aad uga fogaato waxyeelada qaybaha.
• Ka digtoonow signalka PWM; hubi inay ku jiraan xadka la cayimay.
• Hubi isku xirka fiilooyinka si aad uga fogaato wareegyada gaaban.

Tilmaamaha Fiilooyinka

Si aad ugu xirto joystick-ka iyo shaashadda LCD ee Arduino-ga, waxaad ku bilaabaysaa isku xirka binka VCC ee joystick-ka ee 5V-ga Arduino-ga iyo binka GND ee GND-ga Arduino-ga. Ku xir soo-saarka X-dhidibka ee joystick-ka binka analog-ga ah A0 iyo soo-saarka Y-dhidibka binka analog-ga ah A1. Soo-saarka kala-beddelka joystick-ka waa in lagu xiraa binka dijitaalka ah 2.

Shaashadda Nokia 5110 LCD, ku xir biinanka soo socda: VCC ee 5V, GND ee GND, SCE ee binka 7, RST ee binka 6, D/C ee binka 5, DN(MOSI) ee binka 11, iyo SCLK ee binka 13. Ugu dambayntii, ku xir binka LED-ka resistor 330 Ohm ah ee binka 9 si loo xakameeyo iftiinka dambe.

Tusaalooyinka Koodka & Sharaxaad

Faylka setup-ka, waxaanu bilaabaynaa isgaarsiinta serial-ka iyo LCD-ga. Amarka lcdBegin() wuxuu dejiyaa biinanka oo bilaabaa shaashadda. Kala-duwanaanshaha waxaa loo dejiyaa si loo helo muuqaal fiican.

void setup() {
  Serial.begin(9600);
  lcdBegin(); 
  setContrast(40); 
  delay(1000);
  clearDisplay(BLACK);
  updateDisplay();
}

Tani waxay bilaabaysaa qaybaha lagama maarmaanka ah ee mashruuca, iyadoo hubinaysa in LCD-ga uu diyaar u yahay inuu muujiyo macluumaadka.

Faylka loop-ka, waxaanu akhrinaynaa booska joystick-ka oo waxaanu u qaabaynaynaa cabbirrada shaashadda. Booska dhibicda waxaa lagu cusboonaysiiyaa iyadoo lagu salaynayo qiimaha X iyo Y ee joystick-ka.

void loop() {
  int x = analogRead(A0); // akhri booska x ee joystick-ka
  int y = analogRead(A1); // akhri booska y ee joystick-ka
  int xPos = map(x, 0, 1023, 0, screenWidth); // qaabee x ee shaashadda
  int yPos = map(y, 0, 1023, 0, screenHeight); // qaabee y ee shaashadda
  setCircle(xPos, yPos, thickness, BLACK, 2); // muuji dhibicda
  updateDisplay();
  delay(10);
}

Koodkani wuxuu si joogto ah u cusboonaysiiyaa booska dhibicda ee LCD-ga iyadoo lagu salaynayo dhaqaaqista joystick-ka.

Muuujin / Waxa Lagu Filan Karaa

Markaad koronto siiso wareegga, LCD-ga wuxuu muujin doonaa dhibic. Dhaqaaqista joystick-ka waxay dib u dejin doontaa dhibicda waqti-qaar ah iyadoo loo eegayo dhaqaaqyada X iyo Y ee joystick-ka. Haddii kala-beddelka joystick-ka la riixo, waxay kicin kartaa hawlo dheeri ah oo aad hirgelin karto. Ka warqab gelinta sabeynaysa haddii joystick-ku aanu dhexda ku jirin, taasoo keeni karta dhaqaaqyo dhibic oo lama filaan ah (fiidiyowga 01:30).

/* Nokia 5100 LCD Example Code with Added Joystick by Robojax
   Graphics driver and PCD8544 interface code for SparkFun's
   84x48 Graphic LCD.
   https://www.sparkfun.com/products/10168
   Original source code:
https://github.com/sparkfun/GraphicLCD_Nokia_5110

  This stuff could all be put into a library, but we wanted to
  leave it all in one sketch to keep it as transparent as possible.

  Hardware: (Note most of these pins can be swapped)
    Graphic LCD Pin ---------- Arduino Pin
       1-VCC       ----------------  5V
       2-GND       ----------------  GND
       3-SCE       ----------------  7
       4-RST       ----------------  6
       5-D/C       ----------------  5
       6-DN(MOSI)  ----------------  11
       7-SCLK      ----------------  13
       8-LED       - 330 Ohm res --  9
   The SCLK, DN(MOSI), must remain where they are, but the other 
   pins can be swapped. The LED pin should remain a PWM-capable
   pin. Don't forget to stick a current-limiting resistor in line
   between the LCD's LED pin and Arduino pin 9!
