The CY3268 PowerPSoC™ Lighting Starter Kit demonstrates the ability of
PowerPSoC to create scalable LED management solutions and enables designers to
evaluate PowerPSoC. PowerPSoC family of devices features high performance power
electronics including 1A, 2 MHz rated power FETs, hysteretic controllers, current
sense amplifiers, and PrISM™ technology to create a complete solution for LED power
management.
This kit also enables designers to test and evaluate preliminary prototype designs
using PowerPSoC and understand the design flow using PSoC Designer™ software
for the PowerPSoC device family.
WARNING: HIGH BRIGHTNESS LEDs CAN
CAUSE PERMANENT EYE DAMAGE!
Do not look at the LEDs directly if they are not
covered by the protective enclosure. The LEDs
illuminate at a very high intensity and can cause
permanent eye damage if they are viewed without the
protective enclosure.
WARNING: Generally all lab work in power
electronics must be done with extreme care. Caution
must be exercised when using power supplies and/or
power related equipment.

5. Safety precautions
Precautions to be taken when preparing a circuit
Use only isolated power sources (either isolated power supplies or AC power through
isolation power transformers). This helps you to use a grounded oscilloscope and
reduces the possibility of risk of completing a circuit through your body or destroying
the test equipment.
Precautions to be taken before powering the circuit
■Check for all the connections of the circuit and scope connections before power-
ing the circuit, to avoid shorting or any ground looping that may lead to electrical
shocks or damage of test equipment.
■Know your board well - It is recommended to have your board schematic printed
out. Double check your wiring and circuit connections.
Precautions while switching ON the circuit
■Apply only lower current settings (preferably 50mA) while using the hysteretic con-
troller. The demo firmware will be configured for driving 300mA through LEDs.
■After functionality is proven, increase LED current by varying the Hysteretic DAC
thresholds, stopping at frequent levels to check for proper functioning of circuit or
for any components is hot or for any electrical noise that can affect the circuit's
operation. Do not cross the limits for each of the thresholds mentioned in the sam-
ple code.
■Follow the FET turn ON sequence suggested in the demo firmware.
Precautions while switching OFF or shutting down the circuit
Switch of all the power supplies and remove the power supply connections.

4. Create a PSoC Designer Project
4.1 Install Software
To setup the software environment for developing firmware for PowerPSoC
■Install PSoC Designer from the CD (or download the latest version from http://
www.cypress.com/design/SD1099).
■Install PSoC Programmer from the CD (or download the latest version from http://
www.cypress.com/design/SD1062).
For Installation instructions do refer to the instruction in respective web page.
4.2 Hardware Setup
■Attach the supplied power supply to a wall receptacle. Connect the other end of
the power supply to the main board.
■Use miniprog (sold separately) or the ICE (sold separately) to download the firm-
ware to flash and to execute it.
To use the ICE, use blue colored cable (supplied with CY3215 Kit) to connect with the
board or a standard RJ-45 CAT5 cable.
4.3 Example PSoC Designer Project
The first example project demonstrates the ability of the PowerPSoC device to inte-
grate CapSense, LED driving capabilities in one chip. This project sets up the
CapSense buttons, initializes the power peripherals blocks, and enables them. It then
goes into an infinite loop scanning the buttons and performing the required functions.
The CapSense buttons are setup in the following way:
■Button 1: selects HBLED1
■Button 2: selects HBLED2
■Button 3: selects HBLED3
■Button 4: selects HBLED4
■Button 5: Each tap on the button increases the brightness of the selected LED and
when the maximum brightness is reached, starts decreasing. When the brightness
is completely low, further taps start increasing the brightness again.
Steps to write the firmware for example project 1
4.1. Start PSoC Designer 5.0
4.2. Click File > New Project
4.3. Select chip level project as the project type
Page 4 Page 9
e. Click OK to exit the wizard
4.9. To save the project, click File > Save Workspace. To generate the application,
click Build > Generate/Build 'CY3268_Example1' Project.
4.10. Open main.c file from the workspace explorer under the source files category
and replace the content in the main.c file with the content of main.c on CD
included with the kit. The main.c is available in the folder \Demo Firm-
ware\CY3268_Example1\CY3268_Example1.
4.11. To rebuild the project, save the project and click Build > Build
'CY3268_Example1' Project.
4.12. Program the device and check the functionality.
Additional example project is available in the folder \Demo
Firmware\CY3268_Heartbeat. This example cycles through preset colors indefinitely
when the CapSense button CSB5 is tapped. CSB1..CSB4, when tapped turn on/off the
LEDs.
