One function, but is this simple?
No error checking, a lot of really strange constants, mixing Hz and kHz. Do
you like bugs? Do you love bugs? Do you buy a car with only one joystick to
do all operations (including wheel- and oil-change)?
Only one joystick, that means very simple operations! Welcome on the graveyard.
