Ошибка nodmcu max6675 avr/pgmspace.h

Помогите разобраться с компиляцией, если можно - пошагово (запутался напрочь) !!!
стандартные примеры работают
nodmcu v2 12E
max6675 shield`
ide 1.6.4

  Download latest Blynk library here:

  Blynk is a platform with iOS and Android apps to control
  Arduino, Raspberry Pi and the likes over the Internet.
  You can easily build graphic interfaces for all your
  projects by simply dragging and dropping widgets.

    Downloads, docs, tutorials: http://www.blynk.cc
    Sketch generator:           http://examples.blynk.cc

  Blynk library is licensed under MIT license
  This example code is in public domain.


  You’ll need:
   - Blynk App (download from AppStore or Google Play)
   - ESP8266 board
   - Decide how to connect to Blynk
     (USB, Ethernet, Wi-Fi, Bluetooth, ...)

  There is a bunch of great example sketches included to show you how to get
  started. Think of them as LEGO bricks  and combine them as you wish.
  For example, take the Ethernet Shield sketch and combine it with the
  Servo example, or choose a USB sketch and add a code from SendData

/* Comment this out to disable prints and save space */
#define BLYNK_PRINT Serial
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "ррррр";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "YourNetworkName";
char pass[] = "YourPassword";

#include <SPI.h>
#include "max6675.h"
// left_2_right: GND - VCC - NCK - CS - SO
int xSO = 12;               // SO pin of MAX6675
int xCS = 13;               // CS pin on MAX6675
int xNCK = 14;              // SCK pin of MAX6675 (variable SCK cannot be used reserved for RTC) 
float t = 0.00;           // Temperature output variable

// Initialize the MAX6675 Library for our chip
// MAX6675 Library already sets pin modes for MAX6675 chip!
MAX6675 thermocouple(xCS,xSO,xNCK); //two variations on a theme even tried a different library

void setup()
  // Debug console
  Blynk.begin(auth, ssid, pass);
  t = 0;
  // You can also specify server:
  //Blynk.begin(auth, ssid, pass, "blynk-cloud.com", 8442);
  //Blynk.begin(auth, ssid, pass, IPAddress(192,168,1,100), 8442);
  t =(thermocouple.readCelsius());  // Read the temp from the MAX6675
  Blynk.virtualWrite(V21, t);

void loop()
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!

Did you properly install this library?

библиотека установлена
name = MAX6675 библиотека
version = 1.0.0
автор = Adafruit

на страничке гитхаб есть папка исправлений для esp8266

max6675.cpp pgmspace.h location fix for ESP8266

но я не понимаю как это сделать

с Nano библиотека работает без проблем
с nodmcu у меня не работает…

есть ли решение???

Always a solution… but this is not a Blynk related issue, so I recommend you keep reading other internet posts concerning this sensor and the ESP8266

@Gary99, this is a clip from github hosted library for MAX6675:

#ifdef __AVR
  #include <avr/pgmspace.h>
#elif defined(ESP8266)
  #include <pgmspace.h>

So it seems for me, you are using outdated, non compatible library OR you have selected the wrong board in board selector menu.

дело в том, что без библиотеки max6675 все работает…

я не знаю что делать с этим

#ifdef __AVR
#include <avr/pgmspace.h>
#elif defined(ESP8266)
#include <pgmspace.h>

как изменить библиотеку? куда и как вставить этот клип???..

Just download the GitHub version in case there is no newer version in Arduino Library Manager. Download as zip, properly unpack, and report back what happens.

удалил старую библиотеку
установил с гитхаба


C:\arduino\libraries\MAX6675-library-master\max6675.cpp:9:24: fatal error: util/delay.h: No such file or directory
#include <util/delay.h>
compilation terminated.
Ошибка компиляции.

без библиотеки все ок
не мой день… не знаю как решить
но библиотека точно не подходит для nodmcu v2 esp 12e (cp2102)

Searching Google for:
fatal error: util/delay.h: No such file or directory #include <util/delay.h>
revealed, that there is a problem indeed. Fixing it is relatively easy, but requires you to manually fix some entries in library:

#elif defined(ESP8266)
  #include <pgmspace.h>
  #define _delay_ms(ms) delayMicroseconds((ms) * 1000)

//#include <util/delay.h>
#ifdef __avr__
  #include <util/delay.h>

If you can handle it, it WILL work :slight_smile:

это сработало))
ваша помощь и notepad++ помогло

You welcome :slight_smile:
