hello, i am knew to arduino and programming, although i am good with wiring and things like that. i got this example code online for an 8x8 matrix, and i have (attempted to) modified it so that it has 16 columns and 8 rows. i am using an arduino mega, two 8x8 led matrices(direct drive) and i have the row pins linked to each other, row pin 1 linked with 1, 2 linked with 2, and so on. so far, all that is happening is that all of the led are lighting up. if anyone could look at the code that would be great, thanks.
i have included the code as a .ino file
