2.0 Functional overview
The JoyWarrior family of joystick controllers
allows to build USB compatible input devices
without the need to acquire USB know how.
Mostly only electro-mechanical components need
to be added to the JoyWarrior chips.
With the wide variety of controller versions most
industrial and game control devices can be built
very easily.

4.4 Pin descriptions
D+, D-
Differential data lines of USB. Connect these
signals direct to a USB cable. D- requires a pull up
resistor connecting to VREG, see application
circuits for details.
VREG
Supplies 3.3V for the USB D- pull up resistor.
Don't use this pin to supply power to external
circuitry, it does only supply sufficient current for
the pull up resistor.
B0..B7 (JoyWarrior24A8-8)
Inputs for the buttons. Connect contacts closing to
ground.
Internal pull up resistors.
X0/B0..X3/B3 or X0/B0..X7/B7
Matrix row inputs for the buttons. In direct mode
these pins work as direct button inputs, active low,
use contacts closing to ground.
Internal pull up resistors.
Y0/B4..Y3/B7 or Y0/B8..Y3/B11
Matrix column outputs or button inputs for direct
mode. In matrix mode these pins are periodically
pulled low to determine the status of the buttons.
In matrix mode all buttons must be decoupled with
diodes, see application circuit for details.
In direct mode these pins act as active low inputs,
connect contacts closing to ground.
Open drain outputs or inputs with internal pull up
resistor.
Left, Right, Up, Down (JoyWarrior24GP32)
Inputs for the direction pad. Connect contacts
closing to ground.
Internal pull up resistors.
/CS, SCLK, Din, Dout (JoyWarrior24A8L/
A10L)
Signals to connect to the external A/D converter.
JoyWarrior 24A10L requires an external Maxim
MAX1249 A/D converter, JoyWarrior24A8L
requires a Maxim MAX1113.
Internal pull up resistors.
/Pull to GND
This pin is used during production of the
JoyWarrior chips, connect to GND.
A0, A1 (JoyWarrior24A8-x)
The center taps of the pots and a capacitor are
connected to these two pins. The pins are used to
charge the capacitor and measure the time it takes
to discharge the capacitor via the pots.
See application circuits for details.
XR1, XR2, YR1, YR2, ZR1, ZR2
(JoyWarrior24A8-x)
These outputs connect to the outer taps of the pots.
One of them is pulled low at a time to measure
how long it takes to discharge the capacitor via the
pot.
Axis values get smaller when the pot center tap
gets closer to the tap connected to the nR1 pin, i.e.
resistance between nR1 and A0, A1 gets smaller.
RAW (JoyWarrior24A8-x)
Pulling this pin to Vcc disables the autocalibration
and autocentering function. The chip will then
report the raw axis data. This can be useful during
design test or for applications that can't accept the
autocalibration or autocentering feature.
Internal weak pull down resistor.
Direct (all except JoyWarrior24A8-x)
Pulling this pin high disables the matrix scanning
for the buttons and instead uses all button pins as
as direct button inputs for up to 8 or 12
(JW24GP32) buttons pulling to GND.
All button input pins have internal pull ups.
Aux0..Aux3 (JoyWarrior24A8L/A10L)
Auxiliary outputs, active low. Each pin is capable
to sink up to 50mA (70mA combined for all pins).
Push-Pull outputs.
GND
Power supply ground.
Vcc

5.0 Device Operation
By following the USB HID specifications
JoyWarrior chips are able to work with most
operating systems without the need to supply
special drivers. Any operating system with support
for USB HID game controllers will have the
necessary drivers already in place.
5.1 Operation with Windows
Any Windows versions newer than 98 will work
with JoyWarrior. Older versions of Windows do
not support USB or support only a subset of the
functionality.
Upon connecting a JoyWarrior based device for the
first time you may be asked to perform the
standard driver install. The same may happen if
you connect the device to a different USB port on
the same computer. In this case let the system
install the default drivers.
After the driver installation has completed you
should be able to see the device in the "Game
Controllers" control panel and be able to access it
via DirectInput.
5.2 Operation with MacOS
MacOS 9.0 and up and MacOS X do support
JoyWarrior. Some versions of MacOS 8.x do
support USB as well, though their use is not
recommended.
On MacOS X access to the joystick data is
available via the HIDManager.
There will be no warnings or dialogs when a
properly functioning JoyWarrior based device is
connected under MacOS, it will simply start to
work.
5.3 Protocol Specifics: JoyWarrior24GP32
Even though JoyWarrior24GP32 is a gamepad
style device it does report the directional data as a
joystick with two axes of 8 bit each. For left and up
directions 0 is reported, for neutral 127 and for
right and down 255.
This method was chosen since the gamepad data
format does cause problems with several older OS
variants (Mac and PC) and some games.
5.4 Jitter Filter in JoyWarrior24A8-x
Since any A/D converter generates quantisation
noise (the least significant bit jittering at voltages
close to the threshold between two values)
JoyWarrior24A8-x variants (not JW24A8L) use a
simple but efficient jitter filter. Only if the axis
values change more than ±1 digit the data is
actually send to the host. This efficiently
eliminates quantisation noise but retains full
resolution and reaction speed. If there is still noise
on the axis data you should check your circuit for
the cause.
If the RAW pin on the JoyWarrior24A8-x is pulled
high this will also disable the jitter filter.
5.5 Autocalibration and autocentering JoyWarrior24A8-x
The JoyWarrior24A8-x chips do have a
autocentering and autocalibration function that
compensates mechanical tolerances of the joystick.
When autocalibration and autocentering is
activated (i.e. RAW pin is unconnected or pulled to
Gnd) upon power up the JoyWarrior24A8-x will
sample axis data for about 200msec and then use
the current stick position as center. The chip then
assumes that each pot will reach 60% of its total
range and will scale all axis data accordingly to
cover the value range of 0 to 255. If any axis is
moved beyond the assumed range the scaling will
be adjusted.
To calibrate a joystick with the autocentering
feature activated it is sufficient to place the stick to
about center before plugging it in and then move
the stick to all maximum positions. The
JoyWarrior24A8-x will optimize the value scaling
for best resolution.
Pulling the RAW pin high for more than 20msec
and then let it go low again triggers a recalibration.
5.6 Pot and capacitor values for JW24A8-x
The JoyWarrior24A8 is optimized to be used with
a 4.7nF capacitor and 100kΩ pots. A ceramic multi
layer capacitor may be used as the measuring
capacity. It is not recommended to use ceramic
disk type capacitors because of their microphone
effect.
Varying the pot or capacitor values may result in
sub optimal performance. Larger capacitors may
not sufficiently charge or discharge, while smaller
values may introduce more noise.
To optimize the setup it is recommended to check
out the axis values in RAW mode. Ideally the
values in raw mode should range from 0 at one end
of the pot position to 255 at the other end.
5.7 Remote Wakeup
All JoyWarrior chips support the remote wakeup
feature. They are able to wake the host computer
from sleep state if the host operating system does
enable this feature.
Remote wakeup is initiated by JoyWarrior if any
button is pressed or if any switch of the direction
pad closes. Changes on the analog axes are not detected.

5.8 Joystick axis orientation
USB specifies the axis orientation as follows:
For the X axis values should increase for left to
right movement, Y axis values increase for far to
near movements (i.e. pulling the stick gets you
larger values), Z axis values should increase for
high to low movement.
5.9 Non Joystick Applications
USB does allow a Human Interface Device
controller to very detailed specify the function of
axes and buttons. This gives a game controller
device the option to specify a certain axis to be a
throttle or break or something else.
The standard JoyWarrior chips are for general use,
so the analog axes variants just specify X, Y, Z and
the switch inputs are defined as being just buttons.
We can modify the controllers to define axes as
other inputs, like gas or rudder pedals or support
hat switches etc.
However not all available usages are supported by
all operating systems and programs. Windows for
instance supports only a small subset of the
simulation controls page.
If you have special requirements, please contact us
about modifications.
5.10 Auxiliary outputs on JW24A8L/A10L
The JoyWarrior24A8L and JoyWarrior24A10L
chips have four auxiliary outputs that may be used
to drive LED indicators or for other applications.
Due to the significant current sinking cabability of
the outputs they are defined as being active low.
Setting the outputs is done by sending a four byte
Feature report to the joystick device. In most cases
this can be done via standard file I/O functions.
The outputs are set by one byte each, the first byte
sets Aux0, second Aux1 etc.
The bits in the bytes do have the following
meaning:
7 - reserved, write 0
6 - reserved, write 0
5 - reserved, write 0
4 - reserved, write 0
3 - Invert blink mode
2 - reserved, write 0
1 - Mode MSB
0 - Mode LSB
The mode bits determine the behaviour of the
output. Following are the combinations (MSB/
LSB):
00 - Output idle (high)
01 - Output static on (low)
02 - Fast blink mode (1/8th second on/off)
03 - Heart beat blink mode
Heart beat mode switches the output low for 1/16th
second, then high for 1/16th, again low for 1/16th
and then idles high for 13/16th seconds.
The invert bit reverts the ouput status for the blink
modes (no effect on static on/off), this allows to
have two indicators blink in an exactly alternating
pattern.
The output status and blinking is maintained by the
JoyWarrior withoput further host interaction until a
new configuration is send. All outputs go to idle
when the JoyWarrior enters suspend mode.

10. ESD Considerations
JoyWarrior has an internal ESD protection to
withstand discharges of more than 2000V without
permanent damage. However ESD may disrupt
normal operation of the chip and cause it to exhibit
erratic behaviour.
For the typical office environment the 2000V
protection is normally sufficient. Though for
industrial use additional measures may be
necessary.
When adding ESD protection to the signals special
care must be taken on the USB signal lines. The
USB has very low tolerance for additional
resistance or capacitance introduced on the USB
differential signals.
Series resistors of 27Ω may be used alone or in
addition to some kind of suppressor device. In any
case the USB 2.0 specification chapter 6 and 7
should be read for detailed specification of the
electrical properties.
10.1 EMC Considerations
JoyWarrior uses relatively low power levels and so
it causes few EMC problems.
To avoid any EMC problems the following rules
should followed:
• Put the 100nF ceramic capacitor right next to
the power supply pins of the chip and make sure
the PCB traces between the chips power pins
and the capacitor are as short as possible.
• Run the power supply lines first to the capacitor,
then to the chip.
• Make the matrix lines only as long as absolutely
necessary.
• Keep the two USB signal lines close to each
other, route no other signal between them. USB
uses differential signalling so the best signal
quality with lowest RF emission is achieved by
putting these lines very close to each other.
• Adding a ferrite bead to the +5V power supply
line is advisable.
11. Revision History
The initial release version of JoyWarrior is
V1.0.2.0, earlier versions were custom designs not
available for general use.
V1.0.4.1
- First shipping version of JW24A8L and
JW24A10L
V1.0.4.0
- Discontinued JW20 branch of chips.
- Added JW24A8L and JW24A10L
- Added JW24F14 (aka Tomcat) acceleration
sensor.
V1.0.3.B
- Fixed a spurious enumeration problem with
JW20 variants on Linux. JW24 chips are not
affected. On UHCI hosts it was possible that
reading the device descriptors could fail.
Windows and MacOS were not affected due to a
different error recovery method of their system
drivers.
V1.0.3.A
- Customer specific chips, no general release
V1.0.3.9
- Customer specific chips, no general release
V1.0.3.8
