Hallo,
hoffe mir kann hier jemand helfen!
Ich hab ein Problem mit der Library "LiquidCrystal_I2C". Hab sie ganz normal eingebunden und auch die examples funktionieren ohne Probleme. Jedoch im eigentlichen sketch bekomme ich immer wieder den Fehler:
{{{ LiquidCrystal_I2C lcd(I2C_ADDR,En_pin,Rw_pin,Rs_pin,D4_pin,D5_pin,D6_pin,D7_pin); }}}
line. It says [[[no matching function for call to 'LiquidCrystal_I2C::LiquidCrystal_I2C(int, int, int, int, int, int, int, int)']]].
Was mach ich falsch?
