Beginner's help please with LILYGO T-Display S3 ESP32-S3R8

1

Hello everyone,

Before making this post I read as much as I could searching any posts for issues etc, the readme.md file in the T-Display-S3-main folder and followed how to install this version from the github repository into platformio under VSCode.

GitHub - Xinyuan-LilyGO/T-Display-S3 · GitHub

I created a project T_Display_S3_Example01 which has the following (basic?) platformio.ini configuration.

[env:lilygo-t3-s3]

platform = espressif32

board = lilygo-t3-s3

framework = arduino

Is this correct/sufficient for me to start building? I read from a previous post that it may not be and don’t want to be encountering issues as soon as I start, so any help advice on a suitable correct configuration would be kindly received.

Best Regards,

Degs

I have added to the original platformio.ini file (sorry, forgot how to post “code” here)

[env]
platform = espressif32@6.5.0
board = lilygo-t-display-s3
framework = arduino
debug_tool = esp-builtin
upload_protocol = esptool
build_flags = 
	-DARDUINO_USB_CDC_ON_BOOT=1
	-DDISABLE_ALL_LIBRARY_WARNINGS
	-DARDUINO_USB_MODE=1
	-DTOUCH_MODULES_CST_MUTUAL
	-D SERIAL_RX_BUFFER_SIZE=128

[env:My_LCD_Tests]
lib_ignore = 
	GFX Library for Arduino
	arduino-nofrendo
	Adafruit MPR121
	DabbleESP32
	PCF8575 library
	PCA95x5
	lvgl
monitor_speed = 115200

That allows me to select a working sample or my own project when selecting the lily-go t-display “project”. If you don’t want to switch between projects, just delete all the others (make a copy first and save it). That way if something isn’t working, I can switch environments to a working project and potentially see what I’m doing wrong.

Nice little board.

Hello, thank you for this. I’ve done some more digging around today and found a reply from maxgerhardt in oct22, recommending this configuration:

[env:ttgo-display-s3]
platform = espressif32
board = esp32-s3-devkitc-1
framework = arduino
board_build.partitions = huge_app.csv
board_build.arduino.memory_type = opi_qspi
build_flags = -DARDUINO_USB_CDC_ON_BOOT=1

I checked the link as max suggested at the time to the .json file and everything appears set up there. So I intend to start off with the following platformio.ini configuration and attempt to build one of the examples probably the PCBClock example.

[env:ttgo-display-s3]
platform = espressif32@6.12.0
board = esp32-s3-devkitc-1
framework = arduino
board_build.partitions = huge_app.csv
board_build.arduino.memory_type = opi_qspi
build_flags = -DARDUINO_USB_CDC_ON_BOOT=1

Regards,

Degs

Oooopsy…..the PCBClock example has overrun memory available:

Suppose I’d better try a simpler example!

What’s the exact LilyGO model that you’re using? T-Display S3 or T-Display S3 Pro?

6

It’s the T-Display S3 ESP32-S3R8 I’m using.

I’m obviously missing something (apologies). I still have a blank screen after using the ImageScroll example. Everything compiles and downloads successfully. I tried to configure platformio.ini (both ways) but this one below works with the example as the ST7789_DRIVER configuration is in the associated pin_config.h file.

But the screen is still blank, apologies if it’s something simple I’m missing?

Do you have the examples you can download? It was a really big file (around 500Mb), there’s about 25, “run out of the box” examples. I’m pretty sure that they have a download like that (on github) for your board if it’s not the exact same one I’m using. Pops right into platformio, open the project and select your environment (example).

Look for it here, GitHub - Xinyuan-LilyGO/TTGO-T-Display · GitHub, browse around and find your board.

I did find one or two of their examples that didn’t run, not sure why. But I was able to get enough information from the examples to create my own projects. The download had everything, all the libraries you need, the platformio.ini file.

(the github download was about 500Mb, but the actual project folder size in platformio is about 4mb, one of the downloads was about 3G, but not sure what the heck was in that one, looked like everything in the world)

8

I don’t know about that. The repo provides a custom board definition with

Can’t you just create a new folder boards in your project, then put the lilygo-t-displays3.json file inside

https://raw.githubusercontent.com/Xinyuan-LilyGO/T-Display-S3/refs/heads/main/boards/lilygo-t-displays3.json

Then just use

[env:ttgo-display-s3]
platform = espressif32@6.12.0
board = lilygo-t-displays3
framework = arduino
monitor_speed = 115200
lib_deps = bodmer/TFT_eSPI@^2.5.43
build_flags =
  -D ARDUINO_USB_CDC_ON_BOOT=1
  -D USER_SETUP_LOADED=1
  -include $PROJECT_LIBDEPS_DIR/$PIOENV/TFT_eSPI/User_Setups/Setup206_LilyGo_T_Display_S3.h
9

Additionally, the repo has its own TFT_eSPI library (https://github.com/Xinyuan-LilyGO/T-Display-S3/blob/main/lib/TFT_eSPI) and the config file has some interesting changes with regards to the current official TFT_eSPI, e.g. in the T-Display version

is not present in the official version

So it might pay off to just clone <GitHub - Xinyuan-LilyGO/T-Display-S3 · GitHub> and upload a firmware from there, as that uses the TFT_eSPI version contained in that repo. Update the platform version at maximum if there are compilation errors.

Hello Max,

Thanks for all that but I’m a little confused here. The version I downloaded is the one from my first post.

GitHub - Xinyuan-LilyGO/T-Display-S3 · GitHub with this version:

Remove invalid backlight control methods · Xinyuan-LilyGO/T-Display-S3@02f0e9d · GitHub

Which has this platformio configuration settings file as part of the github (code) download.

So what exactly should my platformio.ini file consist of? Obviously I’m completely missing something here as I thought I’d downloaded, cloned and built in platformio the latest github version?

11

For the first test, you don’t need to change any file at all. Simple use the project environment switcher to switch to the provided ImageScroll environment and try to upload it.

Hello Max,

Thanks for this, I now have a display working….big step forward!

I removed my example project from the platformio IDE and left the T-Display-S3-main in the workspace.

In the platformio.ini file I un-commented various examples to test and directed the Switch PlatformIO Project Environment to match accordingly after I’d saved the platformio.ini file.

Examples, Arduino_GFX PDQgraphistest, Arduino_GFXDemo, tft, TFT_Rainbow, ImageScroll, PokerS3 all work fine.

However, even though PCBClock builds and downloads correctly it doesn’t seem to work and remains elusive? The screen still has the last example/displays the last downloaded file?

If I then choose an alternative example like ImageScroll, it works perfectly.

Any suggestions why?

The PCBClock example requires you to fill in the WiFi credentials, did you do that?

DOH!!! Sometimes you just can’t see the trees in the forest :person_facepalming: Many Thanks Max for your patience and help.

Got it all working, the graphics for this version of the clock look amazing.

SO, in conclusion going forward I’ll just copy the platformio.ini configuration that’s suggested with the GitHub download information when I start on my own example project for this device.

On another note Max.

I have a self-balancing two wheeled device (you can’t really say it’s a robot) that I would like to ask many questions on how my well commented version of software is working and the effects I’m experiencing. My background is I’m a retired ex-Chartered Electrical Engineer enjoying learning and building new things. This particular project (knowing about P&ID etc) throws up some strange behaviours each time I power up the platform I’ve built.

Can you suggest a discussion community to share my coding and answer/explain some of the effects I’m seeing. Sometimes the platform is very stable for the ‘cheap’ components and sometimes it’s very erratic/unstable which mystifies me though I have my own conclusions. I’d just like someone more software proficient to review my coding etc?

Thanks once again Max
