EEPROM does not compile (GravityTDS sensor)

[bdimir]

Hardware:

Board: ESP32 DevC Module
Core Installation/update date: ?11/jul/2017?
IDE name: Arduino IDE
Flash Frequency: 40Mhz
Upload Speed: 115200

Description:

I'm trying to connect gravity TDS sensor on ADC14. The code does not compile. On Arduino UNO compiles fine.

Sketch:

#include <EEPROM.h>
#include "GravityTDS.h"

#define TdsSensorPin A14 // gpio 13
GravityTDS gravityTds;

float temperature = 25,tdsValue = 0;

void setup()
{
Serial.begin(115200);
gravityTds.setPin(TdsSensorPin);
gravityTds.setAref(5.0); //reference voltage on ADC, default 5.0V on Arduino UNO
gravityTds.setAdcRange(1024); //1024 for 10bit ADC;4096 for 12bit ADC
gravityTds.begin(); //initialization
}

void loop()
{
//temperature = readTemperature(); //add your temperature sensor and read it
gravityTds.setTemperature(temperature); // set the temperature and execute temperature compensation
gravityTds.update(); //sample and calculate
tdsValue = gravityTds.getTdsValue(); // then get the value
Serial.print(tdsValue,0);
Serial.println("ppm");
delay(1000);
}

There is a bug in the ESP32 EEPROM library. EEPROM.h does not #include Arduino.h. This is not noticeable if you only use the library from a sketch because the Arduino IDE automatically adds #include <Arduino.h> before the sketch's #include <EEPROM.h> but when the EEPROM library is used from another library (as in this case) this is not guaranteed. The solution is to simply move the #include directive from EEPROM.cpp to EEPROM.h.

As for the A1 error, that's because ESP32 does not have an A1 pin. That's a problem with the GravityTDS, not the ESP32 core.

I still have that problem :(
