 Based on a rework of the ssd1306_i2c_oled_u8g2 usermod from the WLED repo.
 
+In December 2024, I made some changes to fix compilation errors, and modified the platformio_override.ini file to include ALL changes needed (no more need to edit the origiginal "stock" platformio.ini file).  I am also forcing an older version of the TFT_eSPI library.

 ## Platformio Requirements
-### Platformio.ini changes
-Under the root folder of the project, in the `platformio.ini` file, uncomment the `TFT_eSPI` line within the [common] section, under `lib_deps`:
-```ini
-# platformio.ini
-...
-[common]
-...
-lib_deps =
-    ...
-  #For use of the TTGO T-Display ESP32 Module with integrated TFT display uncomment the following line  
-    #TFT_eSPI
-...
-```
 
-In the `platformio.ini` file, you must change the environment setup to build for just the esp32dev platform as follows:
+### Platformio_override.ini (added)
+Copy the `platformio_override.ini` file which is contained in the `usermods/TTGO-T-Display/` folder into the root of your project folder. This file contains an override that remaps the button pin of WLED to use the on-board button to the right of the USB-C connector (when viewed with the port oriented downward - see hardware photo).  
 
-Comment out the line described below:
-```ini
-# Release binaries
-; default_envs = nodemcuv2, esp8266_2m, esp01_1m_full, esp32dev, esp32_eth, esp32s2_saola, esp32c3
-```
-and uncomment the following line in the 'Single binaries' section:
-```ini
-default_envs = esp32dev
-```
-Save the `platformio.ini` file.  Once saved, the required library files should be automatically downloaded for modifications in a later step.
+### Platformio.ini changes
+This file isn't actually changed, but it is helpful to save the file in the VS Code application.  This should trigger the download of the library dependencies.
 
-### Platformio_overrides.ini (added)
-Copy the `platformio_overrides.ini` file which is contained in the `usermods/TTGO-T-Display/` folder into the root of your project folder. This file contains an override that remaps the button pin of WLED to use the on-board button to the right of the USB-C connector (when viewed with the port oriented downward - see hardware photo).
+### Change to the WLED_T-Display environment
+This should appear as an option in the bottom toolbar.
 
 ### TFT_eSPI Library Adjustments (board selection)
-You need to modify a file in the `TFT_eSPI` library to select the correct board.  If you followed the directions to modify and save the `platformio.ini` file above, the `User_Setup_Select.h` file can be found in the `/.pio/libdeps/esp32dev/TFT_eSPI_ID1559` folder.

 try building again. Sometimes this happens on the first build attempt and subsequent attempts build correctly.
 
+Once the compilation is done and loaded onto the TTGO T-Display module, you may need to complete the initial setup of WLED via the AP interface, configure the WiFi settings, let it restart and then go to the LED preferences option in the WLED web interface.  The Data GPIO pin needs to be set to pin 2 (or whatever pin you used), and then reboot WLED on the device.  This should get the display working.  I am unable to get the overrides to change the initial pin setting of 16 (which conflicts with the display).
