SH2165 PixiKey™
Programmable Keyboard Encoder
& Force Stick Encoder
HID & SYSTEM MANAGEMENT PRODUCTS, KEYCODER® FAMILY
DESCRIPTION
The SH2165 PixiKey™ is a cost-
effective, high-functionality
combination keyboard and mouse
encoder which offers a
programmable keyboard matrix and
a PixiPoint® strain gauge sensor
interface. It is a USB 2.0 full-speed
device. The SH2165 is ideal for
industrial applications.
The SH2165 scans and encodes
an 8-row by 18-column keyboard
matrix. The encoder retrieves
matrix information from built-in
ROM or a separate serial
EEPROM. Semtech provides
Windows® applications to create
the binary matrix file, and to upload
the matrix to the EEPROM.
The SH2165 PixiKey interfaces
various strain gauge pointing
device sensors.

SH2165
KEYBOARD SCANNER
The SH2165 scans a keyboard organized as an 8 row by 18 column matrix
for a maximum of 144 keys. Smaller size matrixes can be accommodated
by leaving unused pins open. The SH2165 provides internal pull-ups for the
row input pins. When active, the encoder selects each column line (C00-
C17); for each column selected, it reads the row data lines (R0-R7). A key
closure is detected as a zero in the corresponding position of the matrix.
Each key found pressed is debounced for a period of 30 ms. Once the key
is verified, the corresponding key code(s) are loaded into the transmit buffer
of the serial communication channel.
“GHOST” KEY ELIMINATION
In any scanned contact switch matrix, whenever three keys defining a
rectangle on the switch matrix are pressed at the same time, a fourth key
positioned on the fourth corner of the rectangle is sensed as being pressed.
This is known as the “ghost” or “phantom” key problem.
Although the problem cannot be totally
eliminated without using external
Actual key presses
hardware, there are methods to
neutralize its negative effects for most
practical applications. Keys that are
intended to be used in combinations
should be placed in the same row or
column of the matrix, whenever
possible. Shift-type keys (Shift, Alt, Ctrl,
“Ghost”
Key
Window) should not reside in the same
row (or column) as keys of any other
type. The SH2165 has built-in
mechanisms to detect and reject most “ghost” keys.
