/* 04/25/2020 METAR Reporting with LEDs and Local Web Server In Memory of F. Hugh Magee, brother of John Magee author of poem HIGH FLIGHT https://en.wikipedia.org/wiki/John_Gillespie_Magee_Jr. https://youtu.be/Yg61_kyG2zE HomebuiltHELP the video that started me on this project https://youtu.be/xPlN_Tk3VLQ geting started with ESP32 video from DroneBot Workshop. https://www.aviationweather.gov/docs/metar/stations.txt List of all Stations codes. REMARKS: Created by John Pipe with help from David Bird. Made things a little better and squished some bugs. No of Stations = 60 tested 5/24/19 (More possible with extenal power). When Error, successfuly recovers. If not, press "RESET" button on ESP32. The code is stored on the ESP32, so once downloaded, it will automatically restart, even after a power down. LEDS show station category and flashes for gusts(cyan), precipitation(green/white), ice(blue), other(yellow) and info(orange). Also displays for wind(blue), temperature(yellow) and visability(green/white). Station Display shows ALL detailed information and more. Bug Fixes, improvements, repairs to time-space continuum, etc, etc. Modified Significant Weather to include Cloud Cover, RVR & Weather 12/31 Changed to a TIMED 6 Minute METAR read and update 01/07 Added for ice and hail (Blue) 01/30 Added Capability to select any Airport 02/02 Added Summary to HTML 03/04 Cleaned up Get_Time & loop 03/08 Added User 03/10 Added Cloud_base Change Arrows 03/13 Added Alt Pressure Change Arrows 03/13 Added Yellow Misc Weather 03/24 Added Observation Time 04/01 Added Orange Info Changes 04/05 Cleaned up Parse Metar 04/14 Added Wind Change 04/25 */ #include #include #include #include #include WiFiMulti wifiMulti; #include WiFiServer server(80); // Set web server port number to 80 //const char* ssid = "iPhone"; // your network SSID (name) //const char* password = "********"; // your network password const char* ssid = "NETGEAR46"; // your network SSID (name) const char* password = "*********"; // your network password // Setup for Time Server const char* ntpServer = "pool.ntp.org"; const long gmtOffset_sec = 0; // UTC Time const int daylightOffset_sec = 0; // UTC Time struct tm timeinfo; // Time String "%A, %B %d %Y %H:%M:%S" // To get Station Name and Information // Test link: https://aviationweather.gov/adds/dataserver_current/httpparam?dataSource=stations&requestType=retrieve&format=xml&stationString=KFLL //String host = "https://aviationweather.gov"; String urls = "/adds/dataserver_current/httpparam?dataSource=stations&requestType=retrieve&format=xml&stationString="; // To get Station METAR Data // Test link: https://www.aviationweather.gov/adds/dataserver_current/httpparam?datasource=metars&requestType=retrieve&format=xml&mostRecentForEachStation=constraint&hoursBeforeNow=1.25&stationString=KFLL String host = "https://aviationweather.gov"; String urlb = "/adds/dataserver_current/httpparam?datasource=metars&requestType=retrieve&format=xml&mostRecentForEachStation=constraint&hoursBeforeNow=1.25&stationString="; // Set Up LEDS #define NUM_AIRPORTS 81 // Also the number of LEDs CRGB leds[NUM_AIRPORTS]; #define DATA_PIN 5 // Connect to pin D5/P5 #define LED_TYPE WS2812 #define COLOR_ORDER GRB // WD2811 are RGB or WS2812 are GRB #define BRIGHTNESS 20 // LED Brightness max 36 tested /* Define STATIONS & Global Variables First FIVE Characters are IMPORTANT !!
