Trackball
A two axes trackball enables to manage axis
1 and axis 2 (axis 3 is manageable with
keyboard only). 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
resolution or even gravity independency (ex:
Megatron model 816TC).
