Niestety napotkałem na dziwny problem.
Używając standardowego przykładu dla SuplaNodeMCU z przekaźnikiem na gpio2 sam moduł esp dziala poprawnie, łączy się z sewerem itd. W momencie gdy przykład rozszerzę o obsługę oleda z bibliotekami Adafruif,
program działa tylko w teorii
, w teorii, ponieważ nie potrafi się połączyć z wifi.Wystarczy że w programie wstawię :
Code: Select all
display.begin(SSD1306_SWITCHCAPVCC, 0x3C); // initialize with the I2C addr 0x3C (for the 64x48)Oczywiście uruchamiając program bez supli wyświetlanie działa poprawnie.
Jak zwykle programuję w Arduino 1.8.2
Code: Select all
