The VDDIO1 and VDDIO3 power domains are always powered by 3.3 V. The VDDIO0 and VDDIO2
can range from 1.8 V to 5 V depending on the J1 and J4 jumper settings. See Hardware Jumpers on
page 34 for more details.
Note Wireless modules such as ArtaFlex Radio Modules or Cypress Low-power Radio modules
such as CYWM6934/35 (not provided with the kit) can be plugged into the Wireless expansion connector on the board. You can design your own radio module using the Cypress CyFI low-power chip
CYRF7936-40LXI.
2.1.1
Protection Circuit
The protection circuit consists of an 800 mA positive temperature coefficient (PTC) resettable fuse
and a 5.6 V/5 W Zener diode for VDDIO pins on header J2 and J3. When an external voltage more
than 5.6 V is applied, the Zener diode enters the break down region and draws large current. Large
current passing through the PTC fuse cuts off the power line and resets when power supply is disconnected as current or temperature of the fuse reduces. When a revere voltage is applied, the
Zener diode is forward-biased (Vf= 0.7 V) and a closed path is available through the fuse. Hence, a
large current is drawn from the supply leading to a rise in the temperature of fuse. This cuts off the
supply, protecting the PSoC from reverse voltage. Similarly, when a short circuit occurs, the fuse
opens or breaks within 2 ms; this is because a large current is drawn through the fuse, which
increases the temperature of the fuse and protects the regulator. The protection circuit allows twoway power supply at the header allowing you to power externally from 1.8 V to 5.5 V or use the
onboard power supply for powering external components with maximum of around 0.324 V series
drop at 270 mA current across the PTC fuse as the maximum fuse resistance is 1.2 .
2.1.2
ESD Protection on USB Lines
As a best practice, USB lines are protected from ESD up to ±8 kV contact / ±15 kV air discharge by
using the CD143A-SR05LC integrated chip.
2.1.3

Schematic Design PSoC Creator
To view this project's customized hardware configuration, open the TopDesign.cysch file located in
the Workspace Explorer window. PSoC Creator's schematic design entry methodology, using predefined peripheral functions called components, allows rapid hardware definition and
implementation.
The schematic entry system works similar to standard circuit board schematic entry tools, with the
exception that all components and routing are automatically implemented within the PSoC device
rather than on a PCB. This allows you to create custom solutions using peripherals commonly found
in MCU designs as well as analog peripherals, digital peripherals, and logic, not possible with any
other microcontroller or system-on-chip. In many designs, traditionally external resources can be
fully integrated within the PSoC device.
The PSoC Rocks design schematic uses several peripheral and circuit elements. A single analog
input pin connected to the accelerometer's Y axis is routed to an ADC. A pin component with three
pins is used to control the functionality of the accelerometer and another pair is used to drive the
LEDs. The last schematic element is a control register that is used to drive the LED pins. The control
register output is inverted to sink current from the LEDs. This allows the LEDs to be driven externally
with the highest possible current and brightness without adding complexity to the design.
Conventional systems require firmware overhead to decode and invert the data for each of the
affected LED pins.
The PSoC Rocks schematic (see Figure 4-6 on page 18) provides a small sample of how custom
hardware and peripherals are possible in PSoC devices. Each component selected from the
component catalog and placed on to the project schematic provides a GUI, configurable parameters,
and datasheet to further customize its operation in the design. During the project build process, each
component generates the required hardware configuration and firmware APIs as necessary to
provide a truly custom hardware configuration.

Code Examples

4.1.5
How the PSoC Rocks Project Works
This example displays a message using a bank of LEDs, that when swung in a back and forth arcing
motion, produces a rasterized character display. The PSoC 3 FirstTouch Starter Kit has a three-axis
accelerometer. The accelerometer detects the instant acceleration of the board when in motion. The
instantaneous voltage at each axis of the accelerometer is directly proportional to the acceleration
along that axis.
In this project, the firmware uses the Y axis voltage output of the accelerometer. This voltage is
routed to an ADC in the PSoC. This digital value is now a measure of acceleration detected by the
accelerometer. If the acceleration exceeds a maximum value, it signals the start of a new wave
event. The firmware delays for a fixed period of time to start the first character in the proper position
of the wave. The current string is converted into a rasterized display data array before the start of the
wave. Each column of the rasterized data array is sequentially output after a fixed delay. The delay
periods may be adjusted in firmware.
For a particular character in the message, a look up table determines which LEDs to turn on. When
the board is waved back and forth rapidly, due to persistence of vision, the user defined image
appears to float in the air. Multiple strings may be configured with each string being displayed for an
adjustable number of wave cycles.

How the Bubble Level Emulator Project Works
A bubble level displays the amount the level deviates from horizontal using a bubble of air in a glass
via level. In this project, a level is emulated by the accelerometer on the board.
In bubble level detection, LEDs display the tilt of the board along its length (corresponding to the X
axis of the accelerometer).
The accelerometer is always under the influence of gravity. When the board is placed flat on the
ground, the static acceleration due to gravity along the X axis of the accelerometer is zero. In this
position, the two LEDs in the center of the LED display are turned on. Because the board is tilted in
one direction, the force of gravity along that axis increases. This increases the static acceleration
detected by the accelerometer. The X axis voltage output of the accelerometer is fed into an ADC in
the PSoC. The ADC converts this voltage into digital count, which is the measure of the static
acceleration detected by the accelerometer. PSoC determines the tilt of the board and lights up
LEDs indicating the tilt. If the board is further tilted in one direction, the LED moves accordingly to
the extreme of the LED display.

and vice-versa.
4.3.1
How the ThermistorTemperatureSense Project Works
The thermistor example demonstrates how the PSoC device senses temperature using a thermistor.
The thermistor resistance varies with temperature following a predictable nonlinear curve. The
temperature-resistance relationship is given by the Steinhart-Hart equation:
1 /Tk = A + B*ln(R) + C*(ln(R))3
In this equation:
■
A, B, and C are empirical constants known as Steinhart-Hart coefficients.
■
R is the resistance of the thermistor in Ohms.
■
Tk is the temperature in degree Kelvins.
The same equation, when converted to Celsius scale becomes:
Tc = Tk - 273.15
In this equation, Tc is the temperature in degree Celsius.

Temperature Sensing Design Principle
As shown in Figure 4-13, the design for temperature sensing uses a voltage divider with a precision
resistor on one side and the thermistor on the other to estimate the thermistor resistance. The
temperature calculations are as accurate as the resistance measurement of the thermistor.

This setup significantly removes gain and offset errors from the resistance calculation.
The analog voltage output from the divider is converted to a digital signal using the ADC on the
PSoC. To gain additional accuracy, the voltage at the input side of the divider is also measured. The
resistor value is calculated using the ratio of the voltages across two resistors in the resistor ladder.
Rthermistor = Rref * (V1-V2/V0-V1)
In this equation, V2 = 0 (Ground voltage)
Offset errors, if any, are removed due to subtraction of the two measured voltages. The ratio of these
two values removes the measurement path gain error. The error due to the reference resistor is
reduced by using a precision resistance in series with the thermistor.
CY8CKIT-003 PSoC 3 FirstTouch Starter Kit Guide, Document # 001-49613 Rev. *H
25
Code Examples
Temperature is calculated by referring to a table of 165 known points on the resistance/temperature
curve using a look up table. The table holds resistance values of the thermistor from –40 °C to
125 °C, in 1-°C increments. Linear interpolation is used between the points in the table for
temperature calculation up to two decimal places.
The temperature is then displayed as a rasterized image using persistence of vision when the board
is waved around. See section How the PSoC Rocks Project Works on page 18 to understand how
the message is displayed on the LEDs.
For more information on using PSoC family devices with a thermistor, see the application notes

4.4.1
How the CapSense Slider Project Works
Capacitive sensing determines the presence of a conductive element, such as the finger, on a
capacitive sensor incorporated on the PCB. The kit consists of a bank of CapSense sensors in the
form of a slider. The size of the sensors and their position is designed such that when a finger is
placed on any part of the slider, at least three sensors are active (it detects the presence of the finger
by a change in its capacitance value).
The CapSense component provides APIs, which report the centroid (relative position) of the finger
on the slider based on the active sensors. The firmware then lights up the LED corresponding to this
centroid position.

Proximity Sensor
This project senses the presence of a finger near the proximity detection antenna. The number of
LEDs that light up on the LED display on the PSoC 3 FirstTouch Starter Kit board increases as the
finger gets closer to the antenna.
To run the proximity sensor project, follow these steps:
1. Connect the PSoC 3 FirstTouch Starter Kit board to the USB port of the PC through the USB
cable.
2. Click on the ProximitySensor example from Examples and Kits on the Start Page of PSoC Creator.
3. Create a folder in the desired location and click OK.
4. The project opens up in PSoC Creator and is saved in that folder.
5. Follow step 1 to 4 in section Build, Program, and Run the PSoC Rocks Project on page 16 to program the project into the PSoC 3 FirstTouch Starter Kit board.
6. When the download is complete, remove the PSoC 3 FirstTouch Starter Kit board from the USB
port.
7. Attach the wire antenna to the board at the proximity sensor connector and connect the 9-V DC
battery to the battery connector of the PSoC 3 FirstTouch Starter Kit board.
8. Move your finger near and away from the proximity antenna. When your finger comes closer to
the antenna, the number of LEDs that light up increases. When it does not sense your finger or
hand near the antenna, all the LEDs are turned off.

How the Proximity Sensor Project Works
Proximity detection is performed by a proximity antenna acting as a capacitive sensor. The proximity
antenna consists of a wire connected to the proximity connector on the board.
Upon power up, the board establishes a baseline capacitance value of the board along with the
antenna attached to it. This is used as a reference value of capacitance and is called the parasitic
capacitance of the board.
When a conductive object, such as a human finger, is brought close to the antenna, the overall
capacitance of the board changes. This change in capacitance determines the proximity of the finger
to the antenna. An increase in capacitance corresponds to the finger being closer to the antenna.
This is used to light up the LEDs based on the proximity of the finger to the antenna. The number of
LEDs turned on increases as the proximity of the finger increases.
To establish the parasitic capacitance, the antenna must be connected to the board before power up.
The baseline for capacitive sensors is updated continuously by the firmware. This accounts for any
changes in environmental conditions during the operation.

Hardware Jumpers
The PCB has two jumpers to set the power configuration, J1 and J4. These jumpers select the
source for powering the PSoC 3. The options are to power the PSoC 3 from the on board 3.3-V regulator, to run the PSoC 3 from the USB connector, or to supply power from off board using the J2/J3
connectors.
J4 is to select the power source to drive the 3.3-V regulator. This regulator can be used to power
everything on the board or just the accelerometer. The regulator cannot be powered independently
from the VDDIO bus. It must either power the VDDIO bus or be powered by it.
J1 is to select the power source of the PSoC 3. The I/O cells of the PSoC 3 are driven by this source
level. Only the I/O cells that the accelerometer is connected to remain connected to 3.3 V and must
power up with the VDDIO bus or after the VDDIO power bus.
Valid combinations of the jumpers are:
