Trackball
A two axes trackball enables the user to
manage axis 1 and axis 2 (axis 3 is
manageable only from keyboard). Each
channel must have quadrature signal (A,
B).
PEWATRON model LP150-5FV00 is
the reference for this board. It is also
possible to use other kinds of trackballs
with different resolutions or even gravity
independency (ex: Megatron model 816TC).
