Mouse Buttons
Mouse buttons are connected as standard switches.
These switches are pulled up by the pull up resistors
inside the microcontroller. When the user presses a
button, the switch will be closed and the pin will be
pulled LOW to GND. A LOW state at the pin is
interpreted as the button being pressed. A HIGH state
is interpreted as the button has been released or the
button is not being pressed. Normally the switches are
debounced in firmware for 15-20ms. In this reference
design there are three switches: left, Z-wheel, and right.
Optical Navigation Sensor
Avago Technologies ADNS-5030 optical sensor is used
in this reference design as the primary navigation
engine. This Optical Navigation Technology contains
an Image Acquisition System, a Digital Signal Processor,
and a four-wire serial port. The MC68HC908QY4A USB
microcontroller periodically reads the ADNS-5030’s
Delta_X and Delta_Y registers to obtain any horizontal
and vertical motion information happening as a result
of the mouse being moved.
This motion information will be reported to the PC to
update the position of the cursor. The advantages of
using ADNS-5030 optical sensor are the efficient power
management, high tracking accuracy, and flexibility of
programming the optical sensor via the SPI port.
Features include:
• Precise optical navigation technology
• No mechanical moving parts
• Smooth surface navigation
• Auto frame speed
• Accurate motion up to 14ips
• 500/1000 cpi resolution selection
• High speed motion detector
• Single 3.3 volt power supply
• Power conversation mode during times of no
• On chip LED drive with regulated current
• On chip resonator
• Serial port registers
