serial display examples matrix orbital display

well i thought serial.print was replaced with the .write anyway it said that when i tried to compile/send it hence i replaced them all.

also random question is TTL to do with serial or does it have to to with i2c if i try to hook it up that way. There are jumpers that let the display talk using ttl just wondering if i need to worry about ttl for i2c for troubleshooting.
