What is the Problem?

[ragnaroek74]

Hello!

Unfortunately, I'm still a newbie when it comes to working with the Arduino. I have successfully completed a few projects. Unfortunately, I'm completely lined up for Mega Chess 2 and don't know what to do next.
I can't get ArduinoMegaChess2.ino to work. Unfortunately, I couldn't find anything with the error messages on Google either. I have already solved some problems with gui.h.
My display https://www.amazon.de/dp/B07Y6179LG/ref=pe_27091401_487027711_TE_SCE_dp_1

At the end I send a few more error messages of well over 100! with.

Please help! Thanks

Post your code between code tags </> well outlined. Copy your errorcode. A screendump is a bad choice.

The greatest problem is #define EFC isn't declared the right way.

Tip: not the last error in the row is the most important. The first error is important. All the rest can be a result of the first error.

Thanks for the information!
Have used the code completely divided into white section and the red part. I already know that the white ones aren't that bad. I tried to exchange the EFC file and the associated one for a new one. Unfortunately, there was no success.

Thanks

[TomGeorge]

Hi,
It would be good if you posted your complete code so we can see where the errors are referenced to.

Thanks... Tom...

[StefanL38]

looks like some libraries are missing.
Post the link to the description of the project.
post your complete sketch. The forum software can take 120.000 characters of code

[hammy]

Any use ?

DueFlashStorage.

It looks like the MegaChess2 sketch is using code for an Arduino DUE. What model Arduino are you compiling for?

[johnwasser]

I tried downloading the four source files from here:
https://projecthub.arduino.cc/Sergey_Urusov/67ce033a-4696-4dbf-b492-2718896b60c5

Line 1009 of ArduinoMegaChess2.ino is missing a '/' from a comment

I had to switch gui.h from mcufriend480 to adafruit320.

I had to install the Adafruit_TFTLCD library.

Now it compiles with just warnings.

Sketch uses 86852 bytes (34%) of program storage space. Maximum is 253952 bytes.
Global variables use 6309 bytes (77%) of dynamic memory, leaving 1883 bytes for local variables. Maximum is 8192 bytes.

[ragnaroek74]

I'll try that right away.
I use a MEGA R3.
My Display from Amazon. .
Since this is a different display than in the project, I modified the gui.h at the beginning with the correct data.

But I have now run through the gui.h again and there are already many errors.
I think I'll leave chess, I still don't know enough for that...

Thank you all very much.

#ifdef Waveshare_ILI9486   
 //(ILI9486 screen 480x320)
 #include <UTFTGLUE.h>
 MCUFRIEND_kbv tft;

Why are you declaring 'tft' as an "MCUFRIEND_kbv" object?

Look at the examples that came with the "Waveshare_ILI9486" library to see what type the object should be. Usually, it would be something like this:
ILI9486 tft;

[ragnaroek74]

@johnwasser

ILI9486 tft;

Thanks for your help, especially to johnwasser!
Fixed the error. Unfortunately the chess is still not working.
Unfortunately I have to admit defeat. I just don't know enough about programming the Arduino. I'm really overwhelmed by this. I have now programmed a test program that works with my hardware. So the TFT works normally. I will now familiarize myself even more with the world of the Arduino IDE and later try to get the chess to work. It doesn't seem to make sense to me at the moment, and my English isn't that good either.
So thanks everyone and maybe the chess will work out and then I'll post it here!

  #define Waveshare_ILI9486
//#define mcufriend480
//#define adafruit320

#ifdef Waveshare_ILI9486   
 //(ILI9486 screen 480x320)
 #include <Waveshare_ILI9486.h>
Waveshare_ILI9486  tft;

 #define screen_height 320 
 #define mapx1 980

 #define mapy1 145
 #define mapy2 902

Recreating a chess program with a different screen and a different microcontroller is a challenge for an experienced programmer (depending on how portable and well written the code is).
Not recommended for a newbie...

[johnwasser]

@ragnaroek74

#define Waveshare_ILI9486
#ifdef Waveshare_ILI9486

Waveshare_ILI9486 tft;

You can't use the same name in both places.

Try:

#define waveshare480
#ifdef waveshare480

[ragnaroek74]

Unfortunately you are right!
Nevertheless I was able to learn something thanks to the forum, even if the project fails in the end.

Very true. If you have the stamina to ask specific questions the project will be 101% sure a success. As long as the users here can see that your knoweldge grows you can ask hundreds of questions and each and every question will be answered.

best regards Stefan

[christop]

You could if it looked like this:

#define Waveshare_ILI9486 Waveshare_ILI9486

Then it'll get expanded to itself at compile time and can be used in an #ifdef directive.
