Errors in compiling esp8266-weather-station-color

HI,

Can somebody help me please.

Recently I bought the esp8266-weather-station-color kit. I am trying to compile the code after changing the setting.h file for my network.

After compiling I get the following errors:

exit status 1

'WiFi' was not declared in this scope

Thanks.

There's quite likely more output than this, isn't there? Did you follow the instructions at https://docs.thingpulse.com/guides/wifi-color-display-kit in particular the "Prepare Arduino IDE for ESP8266" part? I cannot reproduce this with the latest code and ESP8266 Arduino Core  2.9.x and 3.0.x.

Hi Marcel,

Yes I did follow the docs exactly as described. I am pretty new to all of this and have no idea what to do. It should not be that difficult, when the code is copied and compiled.

I might delete everything again and start all over. Will keep you posted.

Thanks for your suggestion.

Kind regards,

Eb W.

Uploaded the esp8266 weather station folder again, checked if the libraries where correct and checked the correct board. All seem to be OK.

Still get this exit error, where 'WiFi and associated declarations' were not declared in this scope.

Any ideas what is wrong???

Thanks.

Kind regards,

To me the smoking gun is right here: `/Users/ebwijkstra/Documents/Arduino/Libraries/esp8266-weather-station-color/esp8266-weather-station-color/esp8266-weather-station-color.ino`.

1. It is very unusual for the project to end up in the Arduino/libraries folder (mine - also on Mac - is empty). True, at https://docs.thingpulse.com/guides/wifi-color-display-kit/#weather-station-color-project we only say "...somewhere to your local file system" but I feel something went wrong here. Why this folder?
2. It is doubly nested: /esp8266-weather-station-color/esp8266-weather-station-color/...

Hallo Marcel,

Thank you for your patience.
I am sure there is nothing wrong with the program, but somewhere on my PC.

I have removed the esp8266 weather-station-color file and placed this folder on a separate drive under 'ThingpPulse. Accessed this drive, double clicked esp8266....ino and it appears on the screen in the Arduino IDE.

Kind regards,

Eb W.

Hi Marcel,

Good news. I finally managed to get the weather station going.
First I tried ou the examples in ESP8266 Weather Station, which worked on de serial monitor ok.
Then I deleted all previous files and folders relating to this weather station.
Downloaded the required libraries and weather-station-color again. Unzipped the esp8266-weather-station-color-master and put it in Documents under 'ThingPulse.
Changed the setting.h file to the correct parameters and bingo after calibration I got the weather station on the TFT screen. So I am very pleased with the result.Thank you again for your help.
Next thing is a small enclosure and as we say: "Bob's your uncle".

Please ignore previous email comment. It is now irrelevant.

Good luck and thanks again for your help and patience.

Kind regards,

Eb W.

Good morning Marcel,

Sorry to bother you again, but I cannot compile the ESP8266 Weather Station. Neither the ESP32.
Whatever I try it does not compile.

I don't understand "I cannot compile the ESP8266 Weather Station. Neither the ESP32." How are the two related? Our kit contains an ESP8266, not an ESP32. Besides, you did have a working setup that compiled back in October. Maybe a general Arduino support forum (e.g. at https://forum.arduino.cc/) would be better suited if you're having trouble with the IDE setup.

Hallo Marcel,

Neither do I why I cannot compile the ESP8266 Weather Station anymore. I had it going as you said in your answer. It is still going without a hick-up, but I cannot reprogram it again or program another Wemos unit.

What I meant with SP8266 and ESP32 is that I have the same errors with the Zihatec sketch, which is based on the ThingPulse sketch.

It has something to do with the WiFi, but what or how I do not know and I do not have the knowledge either.

Only Arduino v2.0 works on my Mac, but it still is an experimental version. The previous versions v1.8.19 and back to v1.8.15 do not open when clicking on the Arduino icon. It is installed, but only a second or two with the splash window, that is all.

Now I usethe winows 10 version on an other computer. Same results.

I do not know anymore what to do. I know it is very difficult to sort out problems in other computers than your own.

My question is really: Why do I get those compiling errors and all to do with WiFi.

Your advice please.

Please accept my apologies.

Best regards,

Eb W.
