Ciao,dal consiglio di questo link : http://forum.arduino.cc/index.php?topic=492121.0;topicseen
ho acquistato i driver della serie mic2981 avendo a disposizione dei led rgb ho creato nel tempo 2 display 7 segmenti.
Assemblato il circuito ho creato un codice [ Allego Codice Anomalo ] per verificare l'accensione almeno nel colore verde dei led rgb.
Questo codice mi ha creato dei problemi ( onestamente non riesco a capire dove sbaglio ) perchè alcuni segmenti mi rimangono accesi a " mezza luce " quando dovrebbero essere spenti.
Non riuscendo a capire se il problema fosse hw o del codice [ Allego Codice NO Anomalia ,ho scritto un altro codice,non proprio uguale,ma penso che mi faccia escludere un " bugs " Hardware,almeno penso.

Allego [ Codice Anomalo ] :

extern unsigned long timer0_millis; //

int digit1 = A2;     				// Display pin xx [ Decine    ]
int digit2 = A1;					// Display pin xx [ Unità     ]

Se qualcuno mi riesce a dare a qualche dritta,lo ringrazio in anticipo.
I led comunque essendo del tipo 5mm non ho potuto pilotarli in serie ,ma ad ogni led una sua resistenza in serie ( Catodo Comune ) e pilotato dall'uscita del driver MICxxxxx.
Tensione di pilotaggio 12Vcc.
Il Codice [ No Anomalia ] lo allego successivamente perchè ,il portale mi dice che ho superato i 9000 caratteri.

Grazie,Mauro

Ma come é il circuito?

mauroplus · Sep 17, 2018, 11:15 pm

Ciao,il circuito in questo momento non l'ho postato perchè lo " disegnato / Bozzato " su foglio di brutta ,potrei metterlo in bella,ma vedendo che il secondo codice " NO Anomalia " mi funziona correttamente,pensavo che non fosse così fondamentale vederlo.
Magari adesso mi metto d'impegno per fare uno schema per Veriifca per gli utenti.
Grazie

mauroplus · Sep 18, 2018, 01:20 pm

Ciao,allego lo schema sperando che si riesca a capire.
Grazie

mauroplus · Sep 22, 2018, 11:36 am

Ciao,onestamente verificando i due codici e il circuito ,mi sembra strano che un codice mi funzioni correttamente rispetto all'altro ,quindi penso il circuito lo debba escludere e ricercare il il difetto sul codice.
Facendo un pò di prove,ho verificato che gli errori " accensione a mezza luce di un segmento che dovrebbe essere spento " sono costanti.

Segmenti accesi a Mezza luce per Numero :

Decine 9 corretto / Unità 1..9 corretti
Decine 8 corretto / Unità 1..9 corretti
Decine 7 corretto / Unità 1..9 corretti
Decine 6 segmento B / Unità 1..9 corretti
Decine 5 segmento B / Unità 1..9 corretti
Decine 4 corretto / Unità 1..9 corretti
Decine 3 corretto / Unità 1..9 corretti
Decine 2 segmento C / Unità 9 segmento E
" 2 segmento C / Unità 8 corretto
" 2 segmento C / Unità 7 segmento D,E,G
" 2 segmento C / Unità 6 segmento G
" 2 segmento C / Unità 5 segmento B,E
" 2 segmento C / Unità 4 segmento D,E
" 2 segmento C / Unità 3 segmento E
" 2 segmento C / Unità 2 corretto
" 2 segmento C / Unità 1 segmento A,D,E,G
" 2 segmento C / Unità 0 segmento G
Decine 1 corretto / Unità 1..9 corretti
Decine 0 sempre Spento corretto / Unità 1..9 corretti

Magari non vuol dire niente,ma forse potrebbe essere un indizio.Intanto vado avanti con le mie prove aspettando magari una dritta dai + esperti.
Grazie
