memoria arduino

[danielealfa]

ciao a tutti ed auguri,
ho fatto un arrocchio con arduino prendendo pezzi qui e la per un menu con lcd , rele' ed dei led ws2812.
mi funziona bene, pero' proprio sul piu ' bello mi dice che ha poca memoria, riesco a fare funzionare 106 led su 112,
ecco il codice

credo che possa risparmiare qualcosa modificando questo"

Codice: Seleziona tutto

  switch(lightPattern) {

ma non ne sono sicuro, se qualcuno gentilmente mi sa rarmi un aiuto su come aggiustare il programma mi farebbe un enorme piacere...sicuramente ho fatto tanti errori,ma come ho detto sono pezzi presi qui e la...
per il momento vi ringrazio
e vi auguro buone feste

Immagino succeda quando cerchi di compilare il prgramma.
Non uso arduino perciò non sono in grado di aiutarti vedo però nel tuo listato una quantità industriale di variabili.
esamina il codice con attenzione dovresti ruiscire in qualche modo a ridurre le variabili.
Ho visto che usi dei float "a naso" usare i float per controllare la luminosità dei led (se ho capito bene l'utilizzo) mi sembra eccessivo se passi a intero dimezzi subito la memoria necessaria. Passare a intero significa lavorare con virgola in posizione fissa, ad esempio i centesimi, il tuo Fade=0,96 diventa Fade=96 ma poi devi stare attento a come fai i conti per non avere overflow. Insomma non è facile spiegare

ciao e grazie della tua risposta.
si succede mentre lo carico, lo ho gia' preso fatto il programma, io non riuscirei a farlo io...
vedo se riesco come mi hai detto te...

ho fatto un arrocchio con arduino prendendo pezzi qui e la per un menu con lcd , rele' ed dei led ws2812.

E qui cominciano i problemi.

se qualcuno gentilmente mi sa rarmi un aiuto su come aggiustare il programma

Non lo farà nessuno. Non ha niente a che vedere con gentilezza, disponibilità o simpatia.
Ho dato il "tuo" codice in pasto a CCCC, che mi ha sputato una complessità ciclomatica di 228

Per capirci, il significato di questo numero s'ha da interpretare come segue:
< 10: programma ben strutturato, testabile e mantenibile
10 < 20: programma con una struttura complessa, accettabile a certe condizioni
20 < 50: programma poco testabile e mantenibile, refactoring necessario
> 50: programma non testabile e non mantenibile. Sintomo di erosione avanzata

Ci sono anche altre metriche interessanti. Per esempio il tuo file ha 1029 linee di codice e 51 funzioni. Una roba così va imperativamente suddivisa in piú moduli!

Quello che tu hai fatto equivale a prendere un centinaio di cavi, ingarbugliarli e chiedere se c'è qualcuno che ha la gentilezza di snodarli e riavvolgerli. L'unica soluzione è il tronchesino.

grazie della risposta, in parole semplici, per riuscite ad guadagnare quel poco di memoria per mettere in funzione gli altri pochi led, come potrei fare ?

Capire cosa fa il codice che hai copiato e adattarlo alle tue esigenze.

troppo complicato per me...
se mettessi 2 nano in seriale e quando vado nel void lamp dal master , invio il comando del tasto allo slave, che mi risponde il void che effettua sarebbe piu' facile?

Ti faccio un semplice elenco di cose che ho notato nel codice che hai allegato:

▪ Come ti è stato detto usi il float quando basta un unsigned char con un fattore di scala e lo hai fatto per un array, peggio ancora, consumi tanta RAM.

▪ Include e define messi in mezzo al codice, indentazione confusa e fatta male, rende tutto il codice poco leggibile.

▪ Troppe variabili globali, si consuma RAM e poi sono fonti di possibili bug.

▪ Dichiari un enum vuoto, è inutile.

▪ Utilizzo di numeri per stati senza l'utilizzo di un define con nome adeguato, rende difficile comprendere il codice.

▪ Utilizzo della funzione pow, è molto lenta e esistono alternative più efficienti visto che l'esponente è intero.

▪ Parti di codice replicate senza utilizzare funzioni generiche, il codice diventa molto voluminoso e rischia di non entrare nella memoria flash

Sei libero di tenerlo, io ti consiglio di studiare meglio la programmazione, esaminare i programmi scritti dagli altri e di riscriverlo. Il codice per i microcontrollori deve essere semplice ed efficiente, altrimenti le poche risorse a disposizione non sono sufficienti e non puoi lamentati del consumo eccessivo di RAM.
