Cheap Yellow Display (CYD) ESP32 Project

Cheap Yellow Display (CYD) is the integration of ESP32 and 2.8" touchscreen display with extended I/O pins and a MicroSD card slot.

  Core Hardware Specs

      ·         Microcontroller: ESP32-WROOM-32 (Dual-core 240 MHz, 520 KB SRAM, 4 MB Flash).
·         Connectivity: Built-in Wi-Fi and Bluetooth.
·         Display: 2.8-inch resistive touchscreen with 320 × 240 px resolution (ILI9341 display       driver, XPT2046 touch controller).
·         Expansion: MicroSD card slot for external storage, plus a few breakout headers for sensors   (e.g., DHT11) and extra GPIO pins.
·         Power: 5V operating voltage via micro-USB or type-C

Note: There are many clones of this board, buy the same model as I used to avoid setup error.

Download Project Codes:

Weather Deck Code

1.First download and extract the arduino code from this drive link
Note: Keep the main code (CYD_weather.ino) and other .h files in the same folder.

2.Install ESP32 board for Arduino IDE (Skip if already installed or follow this simple tutorial) ESP32 installing tutorial

3.Install libraries.

        i. TFT_eSPI

        ii. NTPClient 

        iii. ArduinoJson

4: Setup for pin definition from TFT_eSPI library. 

Download the guideline PDF and setup file (User_Setup.h file) from this drive link

5: How to create a weather API ?

Open a free account on

https://openweathermap.org/  and get your API key.

5:You need to put this key in your arduino code.(CYD_weather.ino file after opening it with Arduino IDE software) See the image below.

 Note: You must enter your timezone to get the clock correct.

Touch Control Dashboard Demo

        1. If you have already setup the TFT_eSPI library by following guideline.

        2. Just download the touch screen library
               XPT2046

        3. Download arduino code from drive link
