My BBQ cooking monitor - ESP8266 dual K-probe via MAX31855 & OLED display

doart · August 2, 2020, 10:31am

Thanks for the reply Peter.
I have updated the Adafruit GFX library as well as all others.
I do not find the ESP8266-12F in the board manager so used the NodeMCU 1.0 (ESP-12E Module) to try to compile it however still the same problem.
I updated the board manager the ESP8266 v2.7.3 is installed.
Here is the verbose output.

‘MAX31855’ does not name a type

I think that is your problem.

It says in post #48 that you should be using this library:

Pete.

doart · August 2, 2020, 1:11pm

Pete thank you so much for your help it is much appreciated indeed.
Yes that was the problem it now compiles OK.
I missed that post #48 it is a blighter when one gets old it is even more so when the eyesight lets you down.
Again thanks now I can proceed.

Hi there BBQ lovers. Dave, thanks for sharing this nice project.

I have a problem using this suggested library: https://github.com/engineertype/MAX31855
“Specified folder/zip file does not contain a valid library”
I have tried with a few other MAX31855 libraries, but no luck.

PeteKnight · January 4, 2021, 2:53pm

Just copy the files from the GitHub site to your Arduino library folder like this:

Pete.

Sasha · January 5, 2021, 7:36pm

Thanks Pete. I have tried that too but still can`t compile. Here is my verbose…

Error compiling for board Generic ESP8266 Module.

PeteKnight · January 5, 2021, 7:40pm

I think you’ve posted the wrong compiler output - that’s mine from post #106

Pete.

Sasha · January 5, 2021, 7:48pm

True. I have updated. I have comparing mine to yours. They are mostly the same except I have some libraries with the newer version. I have also tried to compile it for various boards, but does not help.

PeteKnight · January 5, 2021, 8:10pm

You appear to have a problem with your SimpleTimer installation, which is used by Blynk.

Exactly which board are you using, and why did you change from NodeMCU to Generic ESP8266?

Pete.

Sasha · January 5, 2021, 8:39pm

I have reinstalled both SimpleTimer and Time libraries. I changed to ESP8266 to see if it helps. My board is with ESP8266MOD chip. I have tried to compile it for NodeMCU 0.9 (ESP12 module) too with no luck.

You could try changing from…

SimpleTimer timer;

to

BlynkTimer timer;

Also, it’s sometimes useful to exit the Arduino IDE and fe-open it when you have these ‘couldn’t compile’ errors.

Pete.

Sasha · January 5, 2021, 9:27pm

Tried all. Did not help. I have never had much problem with compiling the code for any project. Pretty discouraging as I know it works for other people, but not to me.

PeteKnight · January 5, 2021, 10:42pm

I’ve just re-compiled the code on my machine and compared the results…

You appear to be running version 1.8.14 of the Arduino IDE.
As of today, the current stable release is 1.8.13 (which is what I’m running), so I assume that you are running one of the ‘nightly build’ preview versions.

What you’ve posted isn’t actually the output that you’d get if you turned-on verbose output during compilation in File/Preferences.
Can I suggest that you turn this on, and post the last 20 lines of output that this produces?

Pete.

Sasha · January 6, 2021, 2:30pm

Pete, I have tried both Arduino IDE versions. The result is the same.
I am confused about the verbose output you have mentioned. It is turned on in file/preferences to be shown for compilation. This is exactly 20 lines after compile attempt in Arduino IDE 1.8.13
I have also tried to use BlynkTimer timer; instead of SimpleTimer timer; in both versions without success.

That’s odd.
When I compile the code with verbose compilation messages turned on, I get 233 lines of data and the last screen-full looks like this…

Interestingly, when I just re-compiled the code just now I received this error…

Using library Time at version 1.6 in folder: C:\Users\Pete Knight\Documents\Arduino\libraries\Time 
Using library RunningMedian at version 0.1.15 in folder: C:\Users\Pete Knight\Documents\Arduino\libraries\RunningMedian 
Using library Adafruit_BusIO at version 1.7.1 in folder: C:\Users\Pete Knight\Documents\Arduino\libraries\Adafruit_BusIO 
exit status 1
Error compiling for board NodeMCU 0.9 (ESP-12 Module).

Then I realised that I hadn’t copied/pasted all of the code and that I was missing the void loop. When I copied/pasted it again and selected all of the code it compiled successfully.

Is it possible that you didn’t copy paste everything from the original sketch?

Pete.

I was hoping I didnt copied the whole code, but that is not the case. All 587 lines of code is there. Is there a way to have some better error log where we can see what exactly is the problem? I am not a programmer, and have no clue how to troubleshoot this other than what Im advised here. It is a pity, but it seams I`ll do my BBQ Amish style.

Try to see if File/Preferences/Compiler Warnings - All gives more information.

Pete.

Dave, restart did not help.
Are you suggesting I install your version of libraries?

Peter, turning on all warnings showed nothing new.

Sasha · January 6, 2021, 11:04pm

Dave, we have the same versions of libraries except my RunningMedian is 0.2.1, and yours is legacy.
