CapSense Best Practices
The Universal CapSense Controller has been created using the best practices for CapSense lay out.
To enable universality and development of the kit and its projects, certain design elements have
been changed from what is recommended for final products. Below is a list of the design features in
the Universal CapSense Controller and what to change for final products.
Design Feature Reason Impact Recommended Change
Sensing traces
routed through a
connector to sensors
Sensing traces
routed to other
schematic elements
Sensing traces
located on the top
layer
Several regulators
used, including a
variable regulator
Test point on CMOD Accessibility of charge/dis-
GND spacing is
generalized for
noise immunity and
sensitivity
Connection to shield
electrode is through
a jumper (module J2)
ESD protection circuitry is not included
UM Parameters set
to supplied overlay
thicknesses
Unused pins are not
routed directly to
GND
0-ohm Resistors
populated throughout
Buttons, sliders and LEDs
placed on the module board to
all for greater flexibility with custom modules for development
and subsequent releases.
Universality of the board
enabled by population/depopulation of 0-ohm resistors
Using vias to route traces to bottom of board and back to connector increases parasitic
capacitance.
Demonstration of CapSense at
several voltages.
charge waveforms
Universality of kit required middle-ground on many parameters
Flexibility of module boards for
both CSD and CSA control
boards
Development/evaluation platform without consistent overlay
is inherently vulnerable to ESD
events
Projects optimized for supplied
hardware
Pins brought out to connector
for subsequent modules or custom designs
Universality of the board
enabled by population/depopulation of 0-ohm resistors
Connectors increase the parasitic capacitance of the sensors,
effectively reducing their sensitivity. Connectors also create
another path for noise to enter
the system.
Solder pads of 0-ohm resistors
increase parasitic capacitance.
Possible noise sensitivity to
stimulus on top side of board.
Finger presses on routing of
control board can lead to sensor
activation.
Global and User Module parameters may need to be verified
with changing power supply.
A test point increases noise sensitivity by acting as an antenna.
Design is not optimized for highnoise or very thick overlays
Higher resistance paths can
impair performance of shield
electrode in CSD projects
Direct or air-separated ESD
testing may impair operation or
damage circuitry. +/-2kV limit on
PSoC pins (see datasheet).
Sensitivity may not be high
enough for very thicker overlays
Possible noise path Tie unused sensing traces
Solder pads of 0-ohm resistors
increase parasitic capacitance
Sensors and control circuitry
should be located on the same
printed circuit board. Lower parasitic capacitance by reducing
trace lengths.
Route traces directly to sensing
elements. Use as few 0-ohm
resistors as possible
Route sensing traces on nonuser side of printed circuit
board. Route sensing traces as
far from noise sources as possible.
Supply one regulated voltage to
PSoC.
Solder-pad test points for leads
offer better noise immunity if test
points are required.
Increase spacing for thicker
overlays and better sensitivity.
Decrease spacing for greater
noise immunity
Dedicated trace for shield electrode. Remove jumpers wherever possible
Include an overlay and ESD protection circuitry
Thicker overlays may require
verification of parameters to
ensure proper operation
directly to ground
Route traces directly to sensing
elements. Use as few 0-ohm
resistors as possible

4. T une a PSoC Express CapSense Project
Note: A CY3240-I2USB Bridge is needed for CapSense tuning. If you do no t have a CY32 40-I2USB
Bridge board, purchase one online by goin g to http://www.cypress.com/design/DK10063, and clicking Buy Online.
The goal of tuning a capacitive sensing application is to adjust the sensitivity of the buttons or slider
so that they accurately detect finger presses. This involves determining which raw counts coming
from the sensor are actual finger presses, or if it is some other stimuli that changes the raw count.
Detailed tuning information is available in the CapSense Guide. In PSoC Express, select Help
Documentation, and select CapSense Guide.

4.20Increase the Finger Threshold to 250 and the IDAC setting to 250. Changing the IDAC setting is
inversely related to the sensitivity of the button. Therefore, increasing the value decreases the
sensitivity. Any Raw Count below the Finger Threshold does not register as a hit.
4.21 Click Apply to Board to write the changed parameter to Flash on the device.
