| + | ** Notiuni din laborator ** | ||
| + | 1. **GPIO** (driver/gpio.h – pentru control pini digitali) | ||
| + | |||
| + | <code cpp>gpio_set_direction((gpio_num_t)BUTTON_FEED, GPIO_MODE_INPUT); | ||
| + | gpio_set_pull_mode((gpio_num_t)BUTTON_FEED, GPIO_PULLUP_ONLY); | ||
| + | gpio_set_direction((gpio_num_t)BUTTON_RESET, GPIO_MODE_INPUT); | ||
| + | gpio_set_pull_mode((gpio_num_t)BUTTON_RESET, GPIO_PULLUP_ONLY); | ||
| + | gpio_set_direction((gpio_num_t)BUTTON_LOG, GPIO_MODE_INPUT); | ||
| + | |||
| + | gpio_set_direction((gpio_num_t)BUZZER_PIN, GPIO_MODE_OUTPUT); | ||
| + | gpio_set_direction((gpio_num_t)VIBRATION_PIN, GPIO_MODE_INPUT); | ||
| + | |||
| + | if (!gpio_get_level((gpio_num_t)BUTTON_RESET)) { | ||
| + | resetFeed(); | ||
| + | delay(300); | ||
| + | } | ||
| + | |||
| + | if (gpio_get_level((gpio_num_t)BUTTON_LOG)) { | ||
| + | showLastLog(); | ||
| + | delay(300); | ||
| + | } | ||
| + | |||
| + | if (millis() > vibrationIgnoreUntil && !gpio_get_level((gpio_num_t)VIBRATION_PIN)) { | ||
| + | // log event | ||
| + | } </code> | ||
| + | |||
| + | |||
| + | 2. **PWM** (ESP32Servo.h – control servo motor) | ||
| + | |||
| + | <code cpp>servo.setPeriodHertz(50); | ||
| + | servo.attach(SERVO_PIN, 500, 2400); | ||
| + | servo.write(180); | ||
| + | delay(500); | ||
| + | servo.write(0);</code> | ||
| + | |||
| + | 3. **SPI** (SPI.h + SD.h – pentru cardul microSD) | ||
| + | <code cpp>#include <SPI.h> | ||
| + | #include <SD.h> | ||
| + | |||
| + | #define SD_CS 5 | ||
| + | |||
| + | if (!SD.begin(SD_CS)) Serial.println("Eroare card SD!"); | ||
| + | |||
| + | File f = SD.open("/log.txt", FILE_APPEND); | ||
| + | if (f) { | ||
| + | f.println(logEntry); | ||
| + | f.close(); | ||
| + | } | ||
| + | |||
| + | File fRead = SD.open("/log.txt"); | ||
| + | if (fRead) { | ||
| + | while (fRead.available()) { | ||
| + | lastLine = fRead.readStringUntil('\n'); | ||
| + | } | ||
| + | fRead.close(); | ||
| + | } | ||
| + | </code> | ||
| + | |||
| + | 4. **I2C** (Wire.h – folosit implicit pentru RTC și OLED) | ||
| + | |||
| + | <code cpp>#include <Wire.h> | ||
| + | #include <RTClib.h> | ||
| + | #include <Adafruit_SSD1306.h> | ||
| + | |||
| + | RTC_DS3231 rtc; | ||
| + | Adafruit_SSD1306 display(SCREEN_WIDTH, SCREEN_HEIGHT, &Wire, OLED_RESET); | ||
| + | |||
| + | if (!rtc.begin()) Serial.println("Eroare RTC!"); | ||
| + | if (!display.begin(SSD1306_SWITCHCAPVCC, 0x3C)) Serial.println("Eroare OLED!"); | ||
| + | |||
| + | DateTime now = rtc.now(); | ||
| + | display.clearDisplay(); | ||
| + | display.setCursor(...); | ||
| + | display.println(...); | ||
| + | display.display(); | ||
| + | </code> | ||
| + | |||
| + | 5. **Intreruperi** (hardware interrupt pe butonul de hranire) | ||
| + | |||
| + | <code cpp>volatile bool feedInterrupt = false; | ||
| + | |||
| + | void IRAM_ATTR onFeedInterrupt() { | ||
| + | feedInterrupt = true; | ||
| + | } | ||
| + | |||
| + | attachInterrupt(digitalPinToInterrupt(BUTTON_FEED), onFeedInterrupt, FALLING); | ||
| + | |||
| + | // in loop(): | ||
| + | noInterrupts(); | ||
| + | bool shouldFeed = feedInterrupt; | ||
| + | feedInterrupt = false; | ||
| + | interrupts(); | ||
| + | |||
| + | if (shouldFeed) { | ||
| + | feed("manuala"); | ||
| + | } | ||
| + | </code> | ||
