 You can create matrix keyboards with any arrangement of keys, but the two most common cases of 3x4 and 4x4 layout number pads have ready-made layouts. There is an example showing usage in detail in both polling and interrupt mode on device pins and an I2C IoExpander.

-IoAbstraction has a very simple unit test framework built into it, it works on a very wide range of boards, more or less everything in our supported list. In addition to this there are mock versions of some components to make testing your code easier.
