ArduinoOpenWeather

What is this?

This is yet another OpenWeatherMap app for UNO R4 WiFi and ESP32.

Inspired by the cool screen design of OpenWeahter by Bodmer, the creator of TFT_eSPI, I migrated it for my UNO R4 WiFi.

Software Requirements

Graphics library

• moononournation/Arduino_GFX v1.6.5

UNO R4 WiFi

Package	Version
Board Platform	Arduino UNO R4 Boards by Arduino 1.5.3
NTP Client	NTPClient 3.2.1
HTTP Client (optional)	ArduinoHttpClient 0.6.1

ESP32

Package	Version
Board Platform	esp32 by Espressif Systems 3.3.8

Software Configuration

1. Open config.h and and configure the following:

   Item	Configuration Parameters
   OpenWeather API	LANGUAGE, LATITUDE and LONGITUDE
   Timezone	TIMEZONE_OFFSET (for UNO R4 WiFi) or TIMEZONE_STRING (for ESP32)
   Screen Rotation	TFT_ROTATION (0,2: portrait / 1,3: landscape)
   SPI GPIO pins	TFT_DC, TFT_MISO, TFT_MOSI, ...

2. Create your secrets.h for WiFi credential and OpenWeather API key:

   #define SECRET_SSID "***** Your SSID *****"
   #define SECRET_PASS "***** Your password *****"
   #define API_KEY     "***** your OpenWeather key *****"

3. Open gfx.cpp and modify the Arduino_GFX code to suit your LCD device:

   #if defined(ARDUINO_UNOR4_WIFI)
   Arduino_DataBus *bus = new Arduino_HWSPI(TFT_DC, TFT_CS);
   Arduino_GFX *tft = new Arduino_ILI9341(bus, TFT_RST);
   #else // ESP32
   Arduino_DataBus *bus = new Arduino_HWSPI(TFT_DC, TFT_CS, TFT_SCLK, TFT_MOSI, TFT_MISO);
   Arduino_GFX *tft = new Arduino_ILI9341(bus, TFT_RST);
   #endif
   
   #define SPI_FREQ    40000000  // or 80000000

4. Experimental Feature

   Symbol	Default
   USE_SECURE_CLIENT	true
   USE_HTTP_CLIENT	false
   DESERIALIZATION_TYPE	TYPE_RAW_STREAM

ToDo List

• Fix the day of the week from 21:00 through midnight.
• Display progress on the opening splash screen.
• Make weather icons multi-colorizing.
• Verify Daylight Saving Time operation.
• Supress debug printing to the Serial Monitor.
