Buongiorno a tutti,
sto scrivendo uno sketch per fare l'impianto di irrigazione del mio orto.
Dal menu devo poter cambiare alcuni parametri così ho scaricato la libreria menubackend da
e dopo vari tentativi sono riuscito a capire come funziona.
Man mano che vado avanti a programmare salvo uno sketch di modo che se combino qualche casino cancello tutto e ricomincio dallo step precedente. Ieri sera avevo due sketch funzionanti e testati su arduino, stamattina mi rimetto al lavoro e mi escono errori che ieri sera non mi dava!!
Anzi, direi solo un errore in tutta la pagina: error variable or field declared void
Questo succede in più di uno sketch salvato (provato e funzionante)
Se posto il codice mi dice che ho superato i 9500 caratteri:
Gli errori che invece mi da sono i seguenti:
menu_con_attuazione:7: error: variable or field 'menuChanged' declared void
menu_con_attuazione:7: error: 'MenuChangeEvent' was not declared in this scope
menu_con_attuazione:8: error: variable or field 'menuUsed' declared void

Che cosa significa? e perché fino a ieri funzionava tutto? Poi dopo aver salvato ho riscontrato questi errori...
Grazie a tutti!

Trovato il problema! Stamattina ho cancellato la cartella Arduino contenuta nella cartella Home (che conteneva la libreria che avevo aggiunto Menubackend)
Grazie a tutti lo stesso!
