Struct GrayCodeLineCounter 

pub struct GrayCodeLineCounter { /* private fields */ }

Utility structure that helps in playing with gray code movement in lines. We assume that chars are 8 lines tall. Some modification are possible for chars of 4 lines

Addresses ordered by lines on screen

0 0x00?? 000 1 0x08?? 001 2 0x10?? 010 3 0x18?? 011 4 0x20?? 100 5 0x28?? 101 6 0x30?? 110 7 0x38?? 111

Adresses ordered by graycode

0 000 => 0 1 001 => 1 2 011 => 3 3 010 => 2 4 110 => 6 5 111 => 7 6 101 => 5 7 100 => 4
