Title: Does it matter which pin is row and which is column?
Post by: yzdnegel on Sat, 26 June 2021, 16:44:36

So if I were to handwire a keyboard, does it matter which one of the pins on the switch is column and which is row?

A switch is just a break in the circuit and when you press it the circuit is completed so it makes no difference which side is which :)

When you build your firmware there's a file where you specify which pins have been used for which rows/columns.

Have a look at this post (https://geekhack.org/index.php?topic=111070.msg3011529#msg3011529).
