Hello All,
I am quite a newbie so please bear with me 
I designed a simple board for general usage which has 2 old new stock 4 digit HP BubbleLed 7seg displays (total of 8 digits) and a MAX7219 to control them via SPI. I have been doing simple projects with it using an UNO just for fun and learning. With the UNO's hardware SPI and the LedControl library everything was quite easy. So I decided to challenge myself by trying to make the same simple projects work on a ATTiny85. Did some research and came across the tinyISP library which seems very promising for adding "somewhat" hardware SPI functionality to the ATTiny without messing with manual bitbanging.
Unfortunately, there aren't much resources or examples about this library, the example sketches that came with it are using shift registers with manual latch pin manipulation (at least that is how I understand from their code) Is it possible to use this library with MAX7219 like the way the hardware SPI works in UNO?
Thanks!
