Add ESP32 in Arduino IDE

Before we can start compiling, the Arduino IDE must have the TTGO-T-Display board, based on an ESP32 in the board selection available. The instruction on https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/ In board selector you can select "ESP32 Dev Module" for TTGO-T-Display.

For MAC users install the "CP210x USB to UART Bridge VCP Drivers" from Silicon Labs, the port to select is /dev/cu.SLAB_USBtoUART in Arduino IDE under tools-->Port

Libraries for Arduino IDE

Now we add libraries for Arduino IDE 1.8.7:
The new api requires a developer key, so you must apply for a key to use https://pro.coinmarketcap.com/account

• TFT_eSPI
• CoinMarketCapApi.h Version 2
• ArduinoJSON version 6.x is testet

Important: Please chose the ESP32 Board libraris the version 1.0.4, version 1.0.5 will not work for now!

The instruction for the "TFT_eSPI" and TTGO-T-Display can be found here https://github.com/Xinyuan-LilyGO/TTGO-T-Display
If you are have problem with the "wifi.h" delete the arduino/libraries/wiFi directory, you can use the esp32 WiFi.h

Case and parts information

You find two files in case directory, .dxf and .stp With the files you can cut stainless steel sheet. I use a laser cuter for this.
