can i control a 16x16 dot matrix using the MAX7219 IC? i know i can drive an 8 digit 7 segment, but can i use it with the 16x16 LED dot matrix??


No it will only do 8 X 8, but you can chain 4 of them for 16 X 16.

The max6954 will do 128 LEDs grouped into eight 4X4 arrays, so you would only need two of those.
