ESP8266 Weather Station
That project is another version of my 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.
I’ve used Gimp to convert them into BMP then used lcd-image-converter to transform them into .h file.
You’ll need to set color profile to R5G6B5 and little-endian.
