Dotychczas moje projekty / kompilacje były dostępne tylko w anglojęzycznej części forum, gdyż nie znam języka polskiego. Jednak z pomocą translatora oraz uprzejmości kolegi z polski (@edm pomaga w tłumaczeniu), postaram się stopniowo przetłumaczyć wszystkie swoje projekty. Także w miarę możliwości, nowe projekty również będę publikował w polskiej wersji. W przypadku pytań, postaram się udzielić odpowiedzi, lecz proszę o wyrozumiałość. Translator różnie tłumaczy, a i kolega pewnie nie zawsze od razu będzie miał czas.
Tym razem firmware umożliwiające pomiar głębokości cieczy z czujnikiem różnicy ciśnień.
Ponadto w firmware zastosowano:
- zaawansowane menu config (tryb konfiguracji),
- kanał RSSI, umożliwia sprawdzenie siły sygnału wifi,
- funkcja aktualizacji oprogramowania OTA (bez konieczności podłączania konwertera USB), w celu podniesienia bezpieczeństwa zastosowano autoryzowany dostęp do aktualizacji,
- możliwość zmiany nazwy modułu na własną z poziomu menu config.
Dla Mpx5010 maksymalnie 1 metr głębokości.
Dla Mpx5050 maksymalnie 5 metrów głębokości.
Dla Mpx5100 maksymalnie 10 metrów głębokości.
Rodzaj czujnika do ustawienia w trybie konfiguracji.
