Hi, I am currently following this course. I am confused right now as why we are giving buffer length to

height*width/8 . I know why we are multiplying by height and width as that is the display height and width but what is purpose of dividing by 8 ? Is this for number of pages? but still I dont understand its concept.

I was working with dot matrix 8x8 controlled by max7219, I followed your videos and I had troubles displaying a character, only one line was turned on, I was trying to figure out the root cause and I found it, it is important to configure the Scale-Limit register in the initialization of this display sending the address 0xXB and the value of 0x07 as register data.
