Witam. Od jakiegoś czasu męczę się z problemem:
Sprzęt jak w tytule ESP8266 (nodemcu v3)
Programowanie w Arduino IDE
Usługi: Webserwer, NTP
czujnik: BME280 (temperatura, wilgotność, ciśnienie)
wyświetlacz: BME280, OLED 128x64
Założenia:
1) Pobierać datę i czas z serwera NTP (jeżeli podłączone WiFi) i wyświetlać na ekranie.
2) Pobrać dane z czujnika i wyświetlić na ekranie oraz na stronie www.
Problem:
Albo rybki albo akwarium. A dokładniej jeżeli chodzi aktualizacja czasu przez protokół NTP to nie startuje WWW. I odwrotnie jeżeli wystartuje WWW to aktualizacja czasu kuleje. Zazwyczaj jest ta pierwsza opcja.
Ktoś ma jakiś pomysł jak to poprawić?
