LED MATRIX AFISAJ ?

Recommended Posts

ok,vad ca nu stie nimeni ce afisaj trebuie,atunci renunt.

dar am gasit alta schema mai simpla la care tot nu ma descurc ,poate ma ajuta cineva 

AT90S2313 este echivalent 100% pin la pin cu ATTINY2313 ? 

si ce setari are fusebiti? (autorul schemei nu-mi raspunde la e-mail)

 

atasez schema

Sa zicem ca ai nevoie de 6 matrice de 8x8, daca da atunci ar trebui sa folosesti un Arduino Nano , 6 MAX7219 si evident 6 matrice de 8x8 cu catod comun. O sa-mi fac un pic de timp si am sa-ti desenez o schema. Poate spui si la ce vrei sa-l folosesti dar oricum prin USB se poate comanda oricind ce sa afiseze.

In principiu sunt echivalente dar sunt generatii diferite iar din acest motiv trebuie intervenit asupra codului putin ca sa-l faci 100% functional pe un attiny2313. Cititi si documentatia atasata mai sus.

In ceea ce priveste fuse-biti, fiecare proiect cu MCU Atmel are propriile lui secrete. Pentru o mai usoara programare a fuse-biti-lor recomand programul de la mikroe "AVR Flash". Am testat in decursul timpul mai multe soft-uri de programare MCU Atmel AVR, incepand cu PonyProg dar pana la urma cel mai comod si rapid de folosit mi s-a parut AVR Flash.
