About the Lilygo ESP32 S3 T-Display board

 

  • LilyGos homep

  • ESP32 S3 duo core 240MHz

  • 1.9" 170x240 pixels OLED color

  • 16 MB Flash, 8 MB PSRAM

    • On image below upper left is 0,0 and lower right is 134,239

  • Uses ST7789V chip as OLED driver ( same as TTGO T1)cp  /Des

    • important to knwo when we are going to configure graphichal driver

INSTALL OF GRAPHICS

We need to install

  1. TFT_eSPI library - is located in the arduino eco system

  2. T-Display-S3 driver

TFT_eSPI install

TFT_eSPI is already in the official arduino library so

  1. Open arduino IDE

  2. Select the LilyGo T-display-S3 as board

  3. In Arduino IDE go to sketch->include library->Manage Libraries

  4. Search for TFT_eSPI and install it ( I have vrs 2.5.43 installed)

We need to configure TFT_ESPI for our S3 lilygo so …

  1. got into sketchbook->libraries->TFT_eSPI

  2. Open file User_Setup_Select.h - wise to c make a backup copy before starting editing ..

  3. I think line 133 looks like - next line

  4. // #include <User_Setups/Setup206_LilyGo_T_Display_S3.h> // For the LilyGo T-Display S3 based ESP32S3 with ST7789 170 x 320 TFT

  5. You must remove the trailing // eg uncomment it so the library is configured to your esp32 …

  6. Before saving file I will suggest you to add a comment just above your edit as I do // JDNMOD sep 24

By search on JDN I can find my modification in “system files”

LilyGo esp32 s3 driver

We need one more to install

  1. the library is here: https://github.com/Xinyuan-LilyGO/T-Display-S3/tree/main/

  2. Download it - use green button click and download as zip file

  3. Unpack zipfile

  4. Locate you arduino library folder. In arduino IDE open File->Preferences. There you can see path to you Sketchbook location

  5. Copy the unzipped folder til your libraries

  6. And rename it o T-Display-S3

datz all

Running examples

Hate to say it, but close your Arduino IDE and restart it - after saving teh config files you have been editing.

Find examples Files->Open-> …sketchbook/libraries/T-Display-S3/examples

You will find - not all is graphics examples
