transform a ArrayBuffer to an array

Hye, Gordon
I need of a byte array (0,1) (pixel OFF, pixel ON) row by raw.
the matrix is on/off not in 8bits.
or i do not understand what is an arrayBuffer...

in your example it is suppose to do that (it's exactly what i need to transfer to my display via serial):

//0,0,0,0,0,0,0,0
//0,1,1,0,0,0,1,1
//0,1,1,0,0,0,1,1
//0,0,1,1,0,1,1,0
//0,0,0,1,1,1,0,0
//0,0,1,1,0,1,1,0
//0,1,1,0,0,0,1,1
//0,1,1,0,0,0,1,1

it does not... why?
