I wanted an NTP clock with time zones and automatic daylight savings time. I found ESP32-2432S028 with a TFT display. You can buy it for under $10 in China, but I paid under $20 in the US so I wouldn't have to wait for shipping.

These instructions have been tested with Ubuntu 22.04.3, Windows 10 and Arduino IDE 2.0.2-2.1.1.

• Remove brltty, an app for blind people, which interferes with ESP32-2432S028. [Ubuntu only]

  sudo apt purge brltty

• Install pyserial which is required by Arduino IDE. [Ubuntu only]

  pip install pyserial

• Start Arduino IDE

• Select Board

  Board is ESP32 Dev Module

  Port is /dev/ttyUSB0 [Ubuntu]

  Port is COM?? [Windows]

  IDE will ask if you want to install esp32 core. The name has changed so you may have to select ESP32 Dev Board and later change to ESP32 Dev Module.

• Install libraries · Use Manage Libraries... to install LovyanGFX(1.1.9) and lvgl(8.3.11) libraries.

• Clone repository

  cd ~/Arduino/

  git clone https://github.com/alannishioka/esp32-2432s028-clock.git

• Copy lv_conf.h to ~/Arduino/libraries/. This assumes lvgl library is in ~/Arduino/libraries/lvgl/

• Edit config.h to input your WiFi ssid/password.

• Connect ESP32-2432S028 to your computer with micro USB cable.

• Build and Install using Arduino IDE

• Fonts were converted with LVGL Online Font Convertor I used condensed because display is taller than it needs to be and so date would fit on a single line.
• Schematic page 1, page 2

• This project is a fork of https://github.com/cjgb/esp32-2432s028-meteo I feel it is fastest to get a project working by starting with something that already works!
• NTP with Day Light Saving Time for the ESP32 also explains how to change the NTP update interval.
