# ESP8266 Weather Station

That project is another version of my [esp32 weather station](https://github.com/paulgreg/esp32-weather-station), using here an esp8266 and a TFT screen to display multiple locations.

## Hardware

  - esp8266

  - ILI9341 TFT screen compatible 3.3V

The ILI9341 TFT display is connected to the esp8266 board as follows:

 - CS pin is connected to D2 (GPIO4),

 - RST pin is connected to D3 (GPIO0),

 - D/C pin is connected to D4 (GPIO2),

 - MOSI pin is connected to D7 (GPIO13),

 - SCK pin is connected to D5 (GPIO14),

 - VCC and BL are connected to pin 3V3,

 - GND is connected to pin GND of the esp8266

Connections to flash esp8266 (if not using NodeMCU)

- VCC to 3.3

- Ground to ground

- RX from FTDI to TX on ESP

- TX from FTDI to RX on ESP

- DTR from FTDI to GPIO 0 on ESP

- RST from FTDI to RESET on ESP

## Arduino env

Copy `parameters.h.dist` to `parameters.h` and update it with your wifi settings and update the locations array (you need to change lat/lng and set your OpenWeatherMap API token).

## Weather API

  * https://openweathermap.org/api/one-call-api

  * create an account and an API KEY

## Icons

Icons are [official icons from OpenWeatherMap](https://openweathermap.org/weather-conditions#How-to-get-icon-URL).

I’ve used Gimp to convert them into BMP then used [lcd-image-converter](https://sourceforge.net/projects/lcd-image-converter/) to transform them into `.h` file.

You’ll need to set color profile to R5G6B5 and little-endian.
