4.1.5
Schematic Design PSoC Creator
This project's customized hardware configuration is viewed by opening the TopDesign.cysch file
located in the Workspace Explorer window. PSoC Creator's schematic design entry methodology,
using pre-defined peripheral functions called components, allows rapid hardware definition and
implementation.
The schematic entry system works similarly 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 are able
to 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 SAR ADC. A pin component with 3
CY8CKIT-014 PSoC 5 FirstTouch Starter Kit Guide, Spec. # 001-57708 Rev. *A

Example Projects
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 would 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 16) provides a small sample of how custom
hardware and peripherals are possible in PSoC devices. Each component selected from the
component catalog and placed onto the project schematic provides a GUI, configurable parameters,
and full data sheet 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.

4.1.6
How the PSoC Rocks and PSoC Rocks SAR ADC Projects Work
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 5 FirstTouch Starter Kit has a three axis
accelerometer. The accelerometer detects the instantaneous 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.
On start of a new wave 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 prior
to 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.

Bubble Level Emulator
This project emulates a glass bubble level instrument using the onboard accelerometer and the LED
display. When the program is run, the LEDs shows the direction in which the board is tilted.
Running the Bubble Level Emulator project:
1. Connect the PSoC 5 FirstTouch Starter Kit board to the USB port of the PC using the USB cable.
2. Click on the example project BubbleLevel from Kits and Solutions present on the Startup page
of the PSoC Creator.
3. Make a folder in the desired location and click OK.
4. Project opens up in the PSoC Creator and gets saved in that folder.
5. Follow step 1 to 4 in section 4.1.3 Build, Program, and Run the PSoC Rocks Project on page 14
to program the project into the PSoC 5 FirstTouch Starter Kit board.
6. When the download is complete, remove the PSoC 5 FirstTouch Starter Kit board from the USB
port and connect a 9V DC battery to the battery connector of the PSoC 5 FirstTouch Starter Kit
board.
7. Tilt the board along the X axis of the accelerometer by holding the battery in a stationary position
and move the edge opposite the battery up and down as shown in Figure 4-10. As you tilt the
board, you could see the direction of the tilt on the LED display.

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 the case of the 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 of the board, the two LEDs in the center of the LED display are turned on. As 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 accordingly
keeps moving to the extreme of the LED display.

Fahrenheit.
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 4-14, 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 the 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-014 PSoC 5 FirstTouch Starter Kit Guide, Spec. # 001-57708 Rev. *A
Example Projects
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. Refer to section 4.1.6 How the PSoC Rocks and PSoC Rocks SAR ADC Projects
Work on page 17 to understand how the message is displayed on the LEDs.
For more information on using PSoC family devices with a thermistor, refer to the application note
AN2017 "Sensing - A Thermistor-Based Thermometer, PSoC Style".

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 5 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 5 FirstTouch Starter Kit board to the USB port of the PC through the USB
cable.
2. Click on the example project ProximitySensor from Kits and Solutions present on the Startup
page of the PSoC Creator.
3. Make a folder in the desired location and click OK.
4. Project opens up in PSoC Creator and gets saved in that folder.
5. Follow step 1 to 4 in section 4.1.3 Build, Program, and Run the PSoC Rocks Project on page 14
to program the project into the PSoC 5 FirstTouch Starter Kit board.
6. When the download is complete, remove the PSoC 5 FirstTouch Starter Kit board from the USB
port.
7. Attach the wire antenna to the board at the proximity sensor connector and connect the 9V DC
battery to the battery connector of the PSoC 5 FirstTouch Starter Kit board.
8. Move your finger near and away from the proximity antenna. As 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
There are two jumpers on the PCB for setting the power configuration. They are J1 and J4. These
jumpers are for selecting the source for powering the PSoC 5. The options are to power the PSoC 5
from the on board 3.3V regulator, to run the PSoC 5 from the USB connector, or to supply power
from off board using the J2/J3 connectors.
J4 is for selecting the power source to drive the 3.3 volt 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 for selecting the power source of the PSoC 5. The I/O cells of the PSoC 5 are driven by this
source level. Only the I/O cells that the accelerometer is connected to remain connected to 3.3V and
must power up with the VDDIO bus or after the VDDIO power bus.
Valid combinations of the jumpers are:
