Adafruit_BMP280.h: No such file or directory

[bebdyshev]

I've been trying to solve this problem for 2 hours now. I installed all the necessary libraries:
C:\Users\kerey\OneDrive\Documents\Arduino\libraries

• Adafruit_BMP280_Library
• Adafruit_BusIO
• Adafruit_Unified_Sensor

Code:

#include <WiFi.h>
#include <WiFiUdp.h>
#include <Adafruit_BMP280.h>

// Константы BMP280
#define SDA_PIN 21
#define SCL_PIN 22
#define BMP280_ADDRESS 0x76
// Библиотека BMP280
Adafruit_BMP280 bmp280;

// Давление на уровне моря (по умолчанию)
double seaLevelPressure = 760.0;
int sec = 1;
// Переменные для хранения данных
float aX, aY, aZ, aSqrt, gX, gY, gZ, mX, mY, mZ, mDirection;
double temp, pres, density, altitude;
float latitude, longitude;

// Параметры Wi-Fi
const char* ssid = "S24 Ultra";
const char* password = "fartuk123123";

// Настройки UDP
WiFiUDP udp;
const char* udpAddress = "192.168.41.76";  // IP-адрес сервера (замените на актуальный IP адрес)
const unsigned int udpPort = 1234;  // Порт сервера

const int potPin=34;
float ph;
float Value=0;

void setup() {

  Serial.begin(115200);

  pinMode(potPin, INPUT);
  delay(1000);
  
  // Инициализация BMP280
  if (!bmp280.begin(BMP280_ADDRESS)) {
    Serial.println("Could not find a valid BMP280 sensor, check wiring!");
    while (1);
  }

  // Подключение к Wi-Fi сети
  WiFi.begin(ssid, password);
  while (WiFi.status() != WL_CONNECTED) {
    delay(1000);
    Serial.println("Connecting to WiFi...");
  }
  
  Serial.println("Connected to WiFi");
  Serial.print("IP address: ");
  Serial.println(WiFi.localIP());
}

void loop() {
  // Чтение данных BMP280
  temp = bmp280.readTemperature();
  pres = bmp280.readPressure();

  // Расчет высоты и плотности
  density = (29.0 * pres) / ((temp + 273.15) * 287.058);
  altitude = 44330.0 * (1.0 - pow(pres / 101325.0, 0.1903));

  Value = analogRead(potPin);
  float voltage = Value * (3.3 / 4095.0);
  ph = (3.3 * voltage);
  String dataString = String(Value) + ";" + String(density) + ";" + String(altitude);
  Serial.println(dataString);
  
  // Отправка UDP пакета
  udp.beginPacket(udpAddress, udpPort);
  udp.print(dataString);
  udp.endPacket();
  
  delay(2000);  // Задержка перед отправкой следующего сообщения
}

This report would have more information with

option enabled in File -> Preferences.`

But it still gives the following error, does anyone know how to solve it?

C:\Users\kerey\OneDrive\Documents\Arduino\libraries

Is 'C:\Users\kerey\OneDrive\Documents\Arduino' the sketchbook directory as specified under file/preferences?

[bebdyshev]

Yes it is
P.S "Документы" means Documents

[UKHeliBob]

The problem is possibly the characters used in the name of the folder

[sterretje]

I think that the non-ascii characters in your path are causing the problem.

I would move the Arduino directory in the path one level up or move it to your documents directory on the C drive.

@bebdyshev

P.S "Документы" means Documents

The name of the folder is "Documents"; and "Документы" is just a link to it - so they are the same for the OS, but not for Arduino. I recommend you to set your "Sketchbook location" in Preferences using the "Documents" folder name rather than "Документы".

Also, the problem might be caused by OneDrive - it is a known issue

Arduino and OneDrive

A couple of years ago, there was a discussion of OneDrive causing problems with the Arduino IDE. I'm running Windows 11. My experience is that even after deleting the OneDrive app, the OneDrive folder persists and subsumes some Arduino files. Trying to move those files and then deleting the OneDrive folder fails to solve the problem because the OneDrive folder gets recreated. Anyone else encountering this issue?

@b707

the problem might be caused by OneDrive

At least in this case, is actually not specific to OneDrive. The fault occurs whenever a library is installed under a path that contains post-ASCII characters, regardless of whether that path is on OneDrive, or just a random normal location on the hard drive.

However, there is a correlation with OneDrive because when you have OneDrive enabled, the user "Documents" folder is automatically named with the localized form of the word "documents". This means that users will experience the bug under the following conditions:

• Windows operating system
• OneDrive enabled
• Default sketchbook location
• Localized (per user's system locale) form of "documents" contains post-ASCII character

However, it could also occur even without OneDrive being enabled, for example if their username contained problematic characters.
