|
||||
|
||||
The Tracker Ball outputs are fed directly into the user port with the port defined as
|
||||
an input. The CB1 and CB2 lines are used in conjunction with PB3 and PB4 for
|
||||
sensing pulses and determining the direction of rotation of the ball.
|
||||
|
||||
The connections are:—
|
||||
CB1 X1
|
||||
CB2 Y2
|
||||
PB0 Left switch button
|
||||
PB1 Middle switch button
|
||||
PB2 Right switch button
|
||||
PB3 X2
|
||||
PB4 Y1
|
||||
|
||||
