why a MAX7221, wouldn't two 595 shift registers have done the same thing?

If you go to the MAXIM website, you can get the 7221 and 7219 as free samples you just need a company or educational email adress.
A shift register will work aswell not neceasarilly in the same manner. I found the shift registers to work well but they are not specificly designed for turning on/off LEDs they are meant more for logic control.

@paraugs If you go to the MAXIM website, you can get the 7221 and 7219 as free samples, you just need a company or educational email adress, they wont send them to Gmail/yahoo etcetera.
