Update with new Coinmarketcap2 API key
Important: update the to new libraries Coinmarketcap2 and ArduinoJSON 6.x
Simple IOTA price ticker by using ESP32 based TTGO-T-Display and CoinMarketcap API for the Arduino IDE platform

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

Now we add libraries for Arduino IDE 1.8.7: Libraries for Arduino IDE
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
- 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
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. Case information
If you like my work, you can give me a tip for a beer :)
