MycilaDS18

ESP32 / Arduino Library for Dallas / Maxim DS18 sensors using RMT peripheral

• This library is using the implementation from https://github.com/junkfix/esp32-ds18b20 based on EP32 RMT peripheral to read the temperature from DS18 sensors.
• It is compatible with Arduino 2 and 3
• It is compatible with the DS18B20 sensor
• Non-blocking and callback support
• Support value expiration

Usage

#include <MycilaDS18.h>

Mycila::DS18 temp;

void setup() {
  Serial.begin(115200);
  while (!Serial)
    continue;

  temp.begin(18);

  // Listen to temperature changes in a callback
  temp.listen([](float temperature) {
    Serial.printf("Temperature: %.2f\n", temperature);
  });
}

void loop() {
  // non blocking read
  if (!temp.read()) {
    Serial.println("Not ready yet");
  } else {
    Serial.printf("Temperature: %s\n", std::to_string(temp.getTemperature().value_or(0)).c_str());
  }
  delay(500);
}
