Hi!

I have copied your DS18B20.h file and made a library DS2438.h with basic read commands.
Would you be interested in adding this .h file to this project?

FYI im knew to github and open source, so i dont know much about how this works.

New full library with DS2438.h, some examples and updated readme.md:

MaximWire.zip

Hello, I’m a high school student and a complete noob when it comes to Arduino.

I’m trying to connect a single DS18B20 probe with the Nano 33 BLE using this guide and it won’t work.

From googling, it seems the OneWire library is incompatible with the Nano 33 BLE?

How do I use the MaximWire library instead? I’ve tried looking at the examples but I can’t really understand it.

I was hoping to use this library to get my temp probe working, but I'm getting a compiler error. Any help is appreciated.

The code is identical to your AnyDevice.ino file except I'm using pin 2.

Hello
Im trying to use this on a Nano and got this error. Please ignore the rest of the code as Im trying to interface the Arduino with a NodeMCU

Here is my code:

#include <stdlib.h>

#include <MaximWire.h>

#define PIN_BUS 2

MaximWire::Bus bus(PIN_BUS);
MaximWire::DS18B20 poolTemp;

Servo myServo;

int SERVOM = A0;
int ONEBUS = 2;

void setup() {
Wire.begin(8); /* join i2c bus with address 8 /
Wire.onReceive(receiveEvent); / register receive event /
Wire.onRequest(requestEvent); / register request event /
Serial.begin(115200); / start serial for debug */
myServo.attach(SERVOM);
myServo.write(0);
}

void loop() {
poolTemp.requestTemperatures();
float temperatureC = poolTemp.getTempCByIndex(0);
float temperatureF = poolTemp.getTempFByIndex(0);
Serial.print("Temperature: ");
Serial.print(temperatureC);
Serial.print("ºC ");
Serial.print(temperatureF);
Serial.println("ºF");

}

char inVal[10];

// function that executes whenever data is received from master
void receiveEvent(int howMany) {
int i = 0;
while (0 <Wire.available()) {

Serial.print(c); / print the character /
inVal[i] = c;
inVal[i+1] = '\0';
i++;
}
int sv = atoi(inVal);
myServo.write(sv);
Serial.println(); / to newline */

Serial.print(inVal);
Serial.println("]");
}

// function that executes whenever data is requested from master
void requestEvent() {
Wire.write("Hello NodeMCU"); /*send string on request */
}

I get an error when I try to compile the AnyDevice example

Every time i want to compile any of your examples I get an error message.

I really want to use your Library and I dont know how i can solve this problem

I see the datasheet of 18b20, Parasite power needs another gpio and an transister to pull up bus strongly less than 10us after send commnad of temperature convertion or writing internel eeprom to provide power, does your lib support it?
