I'm getting this fatal error:
util/delay.h: No such file or directory
when compiling the below sketch:
#include <Wire.h>
#include <Adafruit_ADS1115.h>
Adafruit_ADS1115 ads;
void setup(void)
{
Serial.begin(115200);
ads.setGain(GAIN_ONE);
ads.begin();
}
void loop(void)
{
int16_t adc0, adc1, adc2, adc3;
adc0 = ads.readADC_SingleEnded(0);
Serial.print("AIN0: ");
Serial.println(adc0);
delay(1000);
}
I tried including "Arduino.h" as suggested by friends, but no use. While if I compile with "Adafruit_ADS1x15.h" instead of the above, it do upload but the ADC is not giving values.
Could anybody assist me?

I'm a student, learning about MBEDs. I'm using Nucleo board and the MBED online compiler.
Here's my code:
LM35.h
#ifndef MBED_LM35
#define MBED_LM35
#include "mbed.h"
class LM35
{
public:
LM35(PinName pin);
void mjerenje();
private:
AnalogIn _pin;
};
#endif
LM35.cpp
#include "LM35.h"
#include "mbed.h"
LM35::LM35(PinName pin) : _pin(pin) {}
float temperatura;
void LM35::mjerenje()
{
Serial pc(USBTX, USBRX);
temperatura = _pin.read();
temperatura = (temperatura*5000)/10;
pc.printf("Temperatura je %.2f stupnjeva Celzijevih.\n \r", temperatura);
return temperatura;
}
and here's Main.cpp
#include "mbed.h"
#include "LM35.h"
DigitalOut led1(PC_12);
Serial pc(USBTX, USBRX);
LM35 senzor(PC_0);
int main()
{
senzor.mjerenje();
float temperatura2 = LM35();
pc.printf("%f", temperatura2);
}
I'm having trouble with getting temperatura out of library and using it in main.cpp.
I get following error: Error: No matching constructor for initialization of 'LM35' in "main.cpp", Line: 16, Col: 27
Can someone help me?
in LM35.cpp
void LM35::mjerenje()
return a float value, should be -->
float LM35::mjerenje()
in the main.cpp
float temperatura2;
temperatura2 = senzor.mjerenje();

I'm currently trying to program my M5Stack with an ESP32 chip in it. I downloaded (or atleast I thought) all of the dependencies needed to upload to the board, but I can't even get my program to compile. I downloaded the ESP32 throught the board manager, I followed the M5Stack tutorial on their website and seem to be finding errors in thheir library itself. I'm not sure how to fix, below is my code and below that are the error messages im getting.

This report would have more information with

option enabled in File -> Preferences.
First of all you should do what your compiler wants:
This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.
This gives more details and if the solution is not working edit your question and replace the compiler output with the detailed Info.Include the missinglibs manually in your program
#include <WiFi.h>
#include <SD.h>
#include <M5Stack.h>
#include <Wire.h>
and checkthe dependencies you have in
#include "config.h"
as I could not compile due to missing file
I have my arduino libraries folder which holds one library called DHT_sensor_Library. In this folder, I have another folder called DHT_U. In this folder, I have DHT_U.ccp and DHT_U.h.
The problem is that when I include DHT_U.h in my arduino IDE:
#include "DHT_U.h"
The error says:
Tempreture_Humidity_Sensor:2:19: error: DHT_U.h: No such file or directory
compilation terminated.
exit status 1
DHT_U.h: No such file or directory
I have already tried
#include "DHT_U/DHT_U.h" ,
#include "DHT_U\DHT_U.h"
and
#include ..\DHT_U.h". None of these worked.
This is a snippet of my code:
#include "DHT.h"
#include "DHT_U.h"
#include "LiquidCrystal.h"
#include "DHT.h"
Full code can be shown here:
#include <DHT.h>
#include <DHT_U.h>
// include the library code:
#include <LiquidCrystal.h>
#include "DHT.h"
// set the DHT Pin
#define DHTPIN 8
// initialize the library with the numbers of the interface pins
LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
#define DHTTYPE DHT11
DHT dht(DHTPIN, DHTTYPE);
void setup() {
// set up the LCD's number of columns and rows:
lcd.begin(16, 2);
dht.begin();
// Print a message to the LCD.
lcd.print("Temp: Humidity:");
}
void loop() {
delay(500);
// set the cursor to column 0, line 1
// (note: line 1 is the second row, since counting begins with 0):
lcd.setCursor(0, 1);
// read humidity
float h = dht.readHumidity();
//read temperature in Fahrenheit
float f = dht.readTemperature(true);
if (isnan(h) || isnan(f)) {
lcd.print("ERROR");
return;
}
lcd.print(f);
lcd.setCursor(7,1);
lcd.print(h);
}
How should I fix this?
Try including the hole path like "/home/your_username/arduino/lib/foo.h" or something like this. Are you sure it is a .h file and not a .hpp ?
One thing to consider is that you need to be careful when your #include methods.
If DHT_U.h is located in the same direction as your .ino file you can include it with this:
#include "DHT_U.h"
However, if you installed the library using the library manager from Arduino IDE, you should do:
#include <DHT_U.h>
If none of these works, make sure that you have installed correctly your library. You could try by testing the examples from the Arduino IDE with the library that you have installed.

I found some possible problems:
1 - Arduino IDE version INCOMPATIBLE -- Tried to use 1.8.5, 1.6.12 and failed;
1.6.9 doesn't have INCOMPATIBLE problem. But it still cannot run.
2 - Should install old library of firebase -- still cannot run
