My current project involves writing patterns to an 8x8 LED matrix using two 74HC595 shift registers. I am using a 1088AS matrix for which I found the attached pin allocation diagram. I do not understand the apparently random position of the pin numbers in the diagram.
The pin outputs from the shift registers are, as usual, 15, 1…7. Do I connect the shift register outputs to the corresponding pin numbers in the matrix, or do I connect them to the column and row numbers?
