I have just rewritten joystick code in fully object-oriented fashion.

Earlier DigitalJoystick constructor needed 13 arguments (USB Joystick handle, 5 pins, 5 keys, potx and poty). Now it is constructed from objects xAxis, yAxis and trigger.

• there is no code repetition anymore - both axes are handled by the same class
• the code is easier to read
• the cost? there was no cost, I saved 24 bytes of flash

Comparison side by side is here.

I put "again" in the title because of earlier experiences from my other project (check out "Programming" section). It is actually more efficient to write fully object-oriented code for 8-bit microcontroller.

Unbelievable.
