Zapnutí podsvícení
Vlasta
Dobrý den,
dnes přišel objednaný displej, ale nemá propojku na rozsvícení podsvětlení. Když ho připojím, podsvícení jen problikne a zůstane zhasnuté.
Je nějaký postup, jak to podsvícení trvale zapnout?
Děkuji za radu Vlasta

Už to to svítí

Internet ví na rozdíl ode mě vše. Stačilo do kódu doplnit:
lcd.backlight();
