Hvala na brzom odgovoru i ako sam shvatio MAX7221 je otporniji na smetnje.
E sad na modulima sa MAX7219 koje imam,
paralelno sa napajanjem postoje kondenzatori od 10 uF i 10nF za rasprezanje ali su smetnje i dalje velike i dolazi do gresaka u ispisu.
Napajanje je fabriski SMPS sta jos postaviti protiv smetnji ?

Jos jednom Hvala Smile
