UK weather forecast display using ESP32 and ePaper
...Extremely low power consumption (several weeks between charges)
Idea based on David Bird's original weather display which I couldn't get to work as Weather Underground had closed down (https://github.com/G6EJD/ESP32-8266-ePaper-Weather-Display-Examples)
Programming done using Arduino with the Waveshare ePaper library (https://github.com/waveshare/e-Paper/tree/master/Arduino%20UNO/epd2in13/epd2in13) and the Arduino Json library (https://github.com/bblanchon/ArduinoJson.git)
Hardware:
* TTGO T5 v2.13
* Li-Ion battery
You will need to modify the pin settings in the Waveshare library (epdif.h) to match those that you are using. The pins for the TTGO T5 were found to be:
//TTGO T5
#define RST_PIN 16
#define DC_PIN 17
#define CS_PIN 5
#define BUSY_PIN 4
#define EPD_CLK 18
#define EPD_MOSI 23
