MAX7219 vs MAX7221
#5
Ovo je elektricna sema   [Image: index.php5?title=File:Schmatic.jpg]

Ovako izgleda gotov sklop [Image: index.php5?title=File:Assembled.jpg]

Povezano je 8 kom. u "daisu chain" vezi, dupont zenzko zenskim konektorima duzine oko 15 cm,
odnosno svaki pin D OUT ide na D IN sledeceg modula a svi ostali VCC, GND, CS i CLK  su paralelno vezani.

Signali za CS CLK i D IN na prvom modulu su uzeti sa Raspberry PI B+ takodje kablicima od cca 15 cm

Napajanje je povezano takvim istim kablicima na prvi modul u lancu

Radna temperatura je sobna a raspored prilicno difuzan posto uredjaj jos nije u kutiji ,nije gotov.

Ne znam da li razmisljam u dobrom pravcu ali sam pomislio da sutra "navatam" raznih kondenzatora pa da empirijski probam ....  Smile
