Lambar Arduino da Bidiyo don Nuni na SSD1306 OLED 128 x 32 tare da I2C

A cikin wannan koyawa, za mu bincika yadda ake amfani da nunin SSD1306 OLED 128 x 32 tare da sadarwar I2C akan Arduino. Manufar ita ce nuna abubuwa daban-daban kamar rubutu, rectangles, da ƙimomi masu canzawa kamar voltage da zazzabi akan allo. Wannan saitin ya dace da ayyukan da ke buƙatar ƙaramin nuni mai inganci.

Za mu bi ta hanyar abubuwan kayan aiki da ake buƙata, umarnin wayoyi, da lambar Arduino don samun komai yana aiki. Don jagorar gani, tabbatar da duba bidiyon da ke tare da wannan koyawa (a cikin bidiyo a 00:00).

Bayanin Kayan Aiki

Abubuwan da suka fi muhimmanci don wannan aikin sun haɗa da nunin SSD1306 OLED, wanda shine nuni mai ƙarancin wutar lantarki wanda ke amfani da sadarwar I2C don sauƙin haɗi. Nunin yana da ƙudurin 128 x 32 pixels, wanda ya dace da nuna rubutu da zane-zane masu sauƙi.

Don sarrafa nunin, za mu yi amfani da Arduino board, wanda zai aika umarni da bayanai ta hanyar I2C. Arduino yana sarrafa dabaru na nuna bayanai ta amfani da libraries kamar Adafruit_GFX da Adafruit_SSD1306. Waɗannan libraries suna sauƙaƙe tsarin sadarwa kuma suna ba da damar zana siffofi da rubutu cikin sauƙi.

Cikakkun Bayanai na Datasheet

• Duba adireshin I2C, yawanci 0x3C don OLEDs.
• Tabbatar da samar da wutar lantarki mai kyau don guje wa lalacewa.
• Yi amfani da pull-up resistors don layukan SDA da SCL idan an buƙata.
• Ka sa wayoyi su kasance gajere don rage hayaniya a cikin siginar I2C.
• Yi la'akari da zubar da zafi idan kuna kunna modules da yawa.

Umarnin Wayoyi

Don haɗa nunin SSD1306 OLED, da farko haɗa fil ɗin VCC na nunin zuwa fitarwar 5V akan Arduino. Na gaba, haɗa fil ɗin GND zuwa ɗaya daga cikin fil ɗin ƙasa na Arduino. Don sadarwar I2C, haɗa fil ɗin SDA na nunin zuwa fil ɗin SDA akan Arduino, wanda shine A4 don UNO. Sannan, haɗa fil ɗin SCL na nunin zuwa fil ɗin SCL akan Arduino, wanda shine A5 don UNO. Idan kuna amfani da wani nau'in Arduino daban, koma zuwa takamaiman taswirar fil don SDA da SCL.

Don ƙarin abubuwa, idan kuna da LED da kuke son sarrafawa, haɗa shi zuwa fil 9 ta hanyar resistor na 330-ohm. Tabbatar da haɗa ɗayan ƙarshen resistor zuwa anode na LED, yayin da cathode ya kamata ya tafi ƙasa. Wannan saitin zai ba da damar LED ya haskaka lokacin da fil 9 ya kunna.

Misalan Lamba & Bayani

A cikin lambar Arduino, muna farawa ta haɗa da libraries da ake buƙata don nunin OLED. Wani muhimmin mai ganowa shine display, wanda shine misali na ajin Adafruit_SSD1306. An fara nunin a cikin aikin setup(), inda kuma muke share nunin don shirya zane.

void setup() {
  Serial.begin(9600);
  display.begin(SSD1306_SWITCHCAPVCC, 0x3C);
  display.display();
  delay(2000);
  display.clearDisplay(); 
}

A cikin aikin loop(), muna ayyana maɓallin rubutu vString don riƙe ƙimar voltage, wanda ke canzawa koyaushe. Ana amfani da aikin robojaxText() don nuna rubutu akan allo a takamaiman coordinates.

void loop() {
  String vString = String(count, 3);
  display.clearDisplay();
  robojaxText("Voltage:          ", 4, 3, 1, false);
  robojaxText(vString, 72, 3, 1, false);
  display.display();
  count += 0.173;
  delay(2000); 
}

Aikin robojaxText() yana da muhimmanci don sanya wuri da nuna rubutu. Yana ɗaukar sigogi don rubutun, x da y coordinates, girman rubutu, da boolean don tantance ko ya kamata a sabunta nunin nan da nan.

void robojaxText(String text, int x, int y, int size, boolean d) {
  display.setTextSize(size);
  display.setTextColor(WHITE);
  display.setCursor(x, y);
  display.println(text);
  if(d) {
    display.display();
  }
}

Wannan aikin yana saita girman rubutu, launi, da wurin cursor kafin buga rubutun. Ka tuna ka kalli bidiyon don cikakken bayani na lambar (a cikin bidiyo a 10:00).

Nuni / Abin da za Ka Yi Tsammani

Lokacin da aka ɗora lambar zuwa Arduino, nunin OLED ya kamata ya nuna voltage, zazzabi, da ƙimar capacity suna canzawa kowane daƙiƙa biyu. Ya kamata kuma ka ga rectangle da aka zana kewaye da abubuwan rubutu. Idan nunin bai nuna komai ba, tabbatar da cewa haɗin suna daidai kuma adireshin I2C ya dace da wanda aka ayyana a cikin lambar.
