Your sketch is not compatible with the latest ESP32 board package. There were significant changes when Espressif moved from 2.x to 3.x of their board package. See the migration guide (Migration from 2.x to 3.0 - - — Arduino ESP32 latest documentation).

You can either apply the necessary changes mentioned in the migration guide (I have no idea which ones) or downgrade the board package to version 2.x.

You don't mention which exact board you're compiling for. I've taken the ESP32S3 and encountered your problem; after downgrading the board package to version 2.0.17, it compiles with a warning that needs attention

Hi @Piddepadde.

Explanation

I investigated the issue and found that there is an incompatibility between the default configuration of the "TFT_eSPI" library and the "esp32" boards platform's "WebServer" library.

The problem is that the default configuration of the TFT_eSPI library defines the SMOOTH_FONT macro:

When the SMOOTH_FONT macro is defined, the library defines the FS_NO_GLOBALS macro:

When the FS_NO_GLOBALS macro is defined, the "esp32" platform's "FS" library has a different configuration:

Which then breaks the "WebServer" library, causing the compilation error.

Here is a minimal sketch that demonstrates the problem:

#include <TFT_eSPI.h>
#include <WebServer.h>
void setup() {}
void loop() {}

or even more minimal:

#define FS_NO_GLOBALS
#include <FS.h>
FS *foo;
void setup() {}
void loop() {}

Solution

Fortunately there is a simple solution to the problem. You only need to change the order of the #include directives in your sketch so that the directive for WebServer.h comes before the directive for TFT_eSPI.h.

So change lines 3-5 of your sketch from this:

#include <TFT_eSPI.h>  // Display library for SC-01
#include <time.h>      // time
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager

To this:

#include <time.h>      // time
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager
#include <TFT_eSPI.h>  // Display library for SC-01

Thanks for the suggestions. I have done a reinstallation of the Arduino IDE and downloaded an older version: board package to version 2.0.17. It is an ESP32S3 that I am using. The code has been working before i started to update boards and som libraries - I do not know which but now I have a clean reinstallment and the compilation goes fine but now I have an anoying reboot problem and in the serial monitor it looka like this:

Backtrace: 0x4201998c:0x3fcebc50 0x42019a61:0x3fcebc80 0x42005c93:0x3fcebca0 0x4201f06a:0x3fcebf40

and I cannot find the problem.

I also did a order change in the #include statements to this:

#include <WiFi.h>
#include <HTTPClient.h>
#include <ArduinoJson.h>
#include <time.h>      // time
#include <WiFiManager.h> // https://github.com/tzapu/WiFiManager
#include <TFT_eSPI.h>  // Display library for SC-01

The solution I provided was intended to allow you to use the latest version of the "esp32" boards platform.

Thank you, I will update the esp32 board platform to the latest version and see if the reboot sequence disapear.

Hi, the compilation works even with the updated board version.
I have used the code before and it works fine but now the ESP32S3 board reboots all the time - see the messages that comes in the serial monitor:

Is there anything more than that in Serial Monitor? If not, try resetting the board while Serial Monitor is running to see if it will catch more.

The reason I ask is that the information you shared only tells us that there was an exception, and that the exception is of the "StoreProhibited" type:

https://docs.espressif.com/projects/esp-idf/en/latest/esp32/api-guides/fatal-errors.html#loadprohibited-storeprohibited

LoadProhibited, StoreProhibited

These CPU exceptions happen when an application attempts to read from or write to an invalid memory location. The address which has been written/read is found in the EXCVADDR register in the register dump. If this address is zero, it usually means that the application has attempted to dereference a NULL pointer. If this address is close to zero, it usually means that the application has attempted to access a member of a structure, but the pointer to the structure is NULL. If this address is something else (garbage value, not in 0x3fxxxxxx - 0x6xxxxxxx range), it likely means that the pointer used to access the data is either not initialized or has been corrupted.

Your sketch is very complex so tracking down the cause of the exception might be difficult. Normally when an exception is thrown, a backtrace is printed to Serial Monitor. This backtrace is very cryptic, but there is an extension you can install in Arduino IDE that will interpret the backtrace and give you information about which part of the sketch program code caused the exception. That information might allow you to identify the bug in your code. However, it is only possible to get that information if you have a backtrace to feed the extension.

OK, this does pinpoint the problem to the "TFT_eSPI" library. I see there are some other reports of this problem in the library's bug tracker:

In those reports, it is stated that the problem occurs when using the library with versions of the "esp32" boards platform >2.0.14. So the workaround would be to use the Arduino IDE Boards Manager to install version 2.0.14 of the "esp32" boards platform, then upload the sketch to your ESP32 board again. Hopefully after doing that the problem will no longer occur.

15

Hi again and thank you for your help. To go back to board version 2.0.14 helped to stop the reboot problem but there is another problem:
The screen is black, it seems like the TFT_eSPI library functions doesn't write the screen content.

16

It is best to start a project by using a collection of simple sketches to verify that each individual aspect of the project is working perfectly before you start to combine them into the complete project. It is a bad idea to try to just jump into the thing with a complex sketch like the one you have because there are far too many factors.

You can often use the example sketches that come with most libraries for this purpose if you don't want to write your own test sketches. You will find the TFT_eSPI library's example sketches under Arduino IDE's File > Examples > TFT_eSPI menu. Check to see if the same problem occurs after you upload the relevant example sketch (or your own bespoke test sketch if you prefer) of the library to your board.

I just changed the sections of the lines and there was no problem.
