Problema compilazione errore

Salve ho realizzato questo progetto

L'unica cosa che cambia è il display da me utilizzato e 2.i
8 pollici.
Mi aiutate grazie

Buongiorno,

prima di tutto ti segnalo che, nella sezione in lingua Inglese, si può scrivere SOLO in Inglese (e nella corretta sezione, NON in sezioni a caso)... quindi, per favore, in futuro presta più attenzione in quale sezione metti i tuoi post; questa volta esso è stato spostato, da un moderatore della sezione di lingua Inglese, nella sezione di lingua Italiana ... la prossima volta potrebbe venire direttamente eliminato ...

... dopo di che, essendo il tuo primo post, nel rispetto del regolamento della sezione Italiana del forum (… punto 13, primo capoverso), ti chiedo cortesemente di presentarti IN QUESTO THREAD (spiegando bene quali conoscenze hai di elettronica e di programmazione ... possibilmente evitando di scrivere solo una riga di saluto) e di leggere con molta attenzione tutto il succitato REGOLAMENTO ... Grazie.

Guglielmo

P.S.: Ti ricordo che, purtroppo, fino a quando non sarà fatta la presentazione nell’apposito thread, nel rispetto del suddetto regolamento nessuno ti risponderà (eventuali risposte verrebbero cancellate), quindi ti consiglio di farla al più presto. :wink:

Ok grazie e scusa

Salve, adesso mi risponderanno?

SE qualcuno avrà qualche cosa da dire, certamente risponderà ... ma ricorda che non è un obbligo rispondere ... :wink:

Intanto ti do io alcune altre info ...

  1. per gli errori NON si mette un'immagine, ma si fa il copia/incolla del testo ... che è molto piû leggibile

  2. sembra che tui stia richiamando un font che non hai "incluso" ... controlla bene il codice.

Guglielmo

Guglielmo, come devo fare?

Copia qui il programma che stai compilando e che ti da errore e vediamo (mi raccomando, come da regolamento, il codice, una volta inserito va TUTTO selezionato e va premuta l'icona </> nella barra degli strumenti per contrassegnarlo, appunto come codice. Inoltre, affinché sia ben leggibile, esso deve essere correttamente "indentato" ... questo lo si fa premendo ctrlT su un PC o cmd T su un Mac, all'intero del IDE).

Guglielmo

Allora, tu usi il font "SevenSegmentFull" che però NON fa parte della libreria, ma è un modulo che va scaricato a parte ... lo trovi QUI ... è il secondo dei vari font che puoi aggiungere alla UTFT.

Una volta che lo hai scaricato, mettilo nella cartella del tuo progetto così l'IDE lo trova, lo compila e lo include.

Forse si potrebbe mettere anche nella cartella della libreria, ma se uno poi aggiorna la libreria tutto quello che è stato modificato viene perso, quindi ... meglio metterlo nel progetto che lo usa.

Comunque, sulla pagina della libreria ci sono vari .pdf da scaricare e STUDIARE ... Rinky-Dink Electronics è tra i pochi che documenta come si deve le sue librerie ... approfittatene !!! :wink:

Guglielmo

Ok adesso vado a casa e ci provo grazie

Guglielmo è andato senza errori.
Adesso per far partire il programma su arduino lo devo alimentare la scheda, oppure basta scollegare e ricollegare il cavo usb?

Come preferisci ...
... il programma parte ogni volta che c'è un RESET ovvero o un POR (Power On Reset) quando la scheda viene alimentata o un segnale sul pin di reset che puoi dare premendo, appunto, il pulsante di reset che è presente su Arduino.

Guglielmo

Ho premuto il pulsante reset, ma il display rimane bianco. :frowning:

Ovviamnete, se hai cambiato display rispetto al progetto originale, dovrai andare a modificare o il codice o il .h della libreria per dirgli le caratteristiche del display che stai usando ... come detto ... tocca STUDIARE i .pdf a corredo e capire come personalizzare la libreria in funzione del display usato.

Non avendola mai io usata (NON uso quei display), di più non so dirti ... :roll_eyes:
