Usermods TTGO-T-Display does not compile

[dosipod]

What happened?

When trying to compile https://github.com/Aircoookie/WLED/tree/main/usermods/TTGO-T-Display [On github] you would get errors

 Compiling .pio/build/esp32dev/lib831/TFT_eSPI/TFT_eSPI.cpp.o

I recall facing the same error with other usermods and it was related to below
Bodmer/TFT_eSPI#3048

Other usermods compile fine on older source

To Reproduce Bug

Uncomment the TFT_eSPI line within the [common] section as mentioned in the usermod readme

Expected Behavior

No compile error

Install Method

Self-Compiled

What version of WLED?

0.15.0 (build 2412100)

Which microcontroller/board are you seeing the problem on?

ESP32

@spiff72 FYI if you are the author of this

[softhack007]

It looks like TFT_eSPI verison 2.5.33 is the last one that does not have a compile error with our WLED default framework.

lib_deps =
  ${esp32.lib_deps}
  TFT_eSPI @ 2.5.33  ;; this is the last version that compiles with the WLED default framework - newer versions require platform = espressif32 @ ^6.3.2

[dosipod]

@softhack007 Yeah 2.5.33 seems to compile fine for the TTGO-T-Display usermod . I did not have a display at the moment to test though [ EDIT : compile still fail with 2.5.33]

[spiff72]

I'm not sure I am much help here. I haven't compiled this in a while as I haven't had a need, but I just tried with a fresh download and I am having trouble just getting the stock platformio.ini file to not error out on me. "No option 'build_flags_esp32' in section "common".

I think some PlatformIO stuff has changed since the last time I tried to use it.

[dosipod]

It is fine , seems to NOT compile as listed above , I will be working on re-basing the other usermod from here
https://github.com/Victoare/WLED_TTGO-TDisplay-output

But in the current TTGO-T-Display the TFT_eSPI version 2.5.33 reference should be in the board environment selected and not
globally as softhack highlighted above , seems cleaner that way , once I get a board from someone I will try to clean both

Makes sense. I think I resolved my platformio.ini file issue - it was due to my platformio_overrides.ini file having an error.

I'm a bit confused by the fact that it can't find the WiFi.h library (required in my usermod.cpp file). Has the name of this changed causing this issue?

I also can't figure out why there's no section in the platformio.ini for determining a specific board to compile for. My instructions in the readme.md for the usermod direct you to comment out the "default_envs" line (which lists every env), and to uncomment the in the single binaries section: "default_envs = esp32dev"

[dosipod]

@softhack007 I mixed up old build info but even using TFT_eSPI version 2.5.33 the compile still fails

https://github.com/dosipod/WLED_15/actions/runs/12358075274/job/34487771233

I will edit the post above to indicate that , @spiff72 might be your can still look at fixing that

[spiff72]

I"m stumped here - I can't even get WLED to compile "stock" without my usermod.

I'm also still not clear whether I am doing the compilation specifically for esp32dev correctly. I tried deleting everything in the default_envs line in platformio.ini except for esp32dev, and it appeared to install a much older version of espressif32 (3.5 instead of the already installed 6.9.0).

Clicking the "build" icon at the bottom does nothing, so I tried picking a different env from the bottom status bar in VS Code and picked esp32dev. It then attempts to compile but errors out with some wled_server errors.

I got mine to compile (finally). I had some housekeeping to do - including getting npm installed.

This might be restating what was already mentioned above, but I had to do the following:

• Start with a fresh download of WLED from github
• Copy the usermod.cpp from my usermod folder to the WLED00 folder
• DON'T copy over the platformio_overrides.ini file from my usermod folder
• In the platformio.ini file, uncomment the line under lib_deps to the following:

  #For use of the TTGO T-Display ESP32 Module with integrated TFT display uncomment the following line
    TFT_eSPI @ 2.5.33

• In platformio.ini, change the default_envs line to this:

default_envs = esp32dev

• In the usermod.cpp file, there is a variable called lastUpdate, initialized to zero. Rename it to lastUpdate_mod as shown below and correct the name in the following section as shown here:

long lastUpdate_mod = 0;
long lastRedraw = 0;
bool displayTurnedOff = false;
// How often we are redrawing screen
#define USER_LOOP_REFRESH_RATE_MS 5000

void userLoop() {

  // Check if we time interval for redrawing passes.
  if (millis() - lastUpdate_mod < USER_LOOP_REFRESH_RATE_MS) {
    return;
  }
  lastUpdate_mod = millis();

• At the end of the usermod.cpp file, comment out the tft.print statement containing the currentMilliamps function and replace with placeholder print statement:

  //tft.print(strip.currentMilliamps);
  tft.print("test ");

• Follow the directions in my original readme.md file (in my usermod folder) for the process to configure the User_Setup_Select.h file.

The above allowed me to compile successfully, but I can't confirm the resulting file works because I don't have a TTGO board handy. It may have also been necessary to NOT have powershell terminals open in VS Code when compiling - I swear that was causing me issues too - if I had command prompt "terminals" open it was fine. I also couldn't run the npm install command from powershell terminals - I had to use command prompt.

@spiff72 maybe it's a good time that I get you a bit up-to-date about how to compile WLED - a few things have changed since the last 3 years. It's quite late in Germany where I live, so just a few hints for now. I can give you more info tomorrow.

1. You need to install node.js and git commandline before compiling (looks like you have that part already). Before the very first build - after downloading the source code - you need to run npm install once. Details are in the KB https://kno.wled.ge/advanced/compiling-wled/#preparations (ignore everything except the "preparations" section).

2. Instead of fiddling with default_envs = , you can select the buildenv you want from the VSCode UI. Short how-to (Doc request) compiling in platformio - selecting build envs via dropdown WLED-Docs#161

3. Before anything else, try to build the standard esp32dev. This will confirm your tools are all set up and ready.

4. Do not change platformIO.ini.

5. Now you can create a very short platformio_override.ini for your usermod. The trick is to use extends = esp32dev. Look at examples in platformio_override.sample.ini to understand how to add build_flags and lib_deps to your own build env (this is the part where I have to get some sleep first ;-) it's late now).
