Introduction
1.4 PSoC Development Board
The CY8CKIT-001 PSoC Development Board is designed to aid hardware, firmware, and software
developers in building their own systems around Cypress’s PSoC devices. The flexibility to configure
the power domains is one of the foremost features of this board. Input power to the board is from one
of two sources:
■12 V 1-A power supply adapter
■9-V alkaline battery (not included)
This full-featured board incorporates three onboard linear regulators that power peripherals and
PSoC processor modules at voltages between 1.7 V and 5.0 V. These regulators include a fixed 5 V
1-A linear regulator, a fixed 3.3 V 300-mA linear regulator, and a 1.5 V to 3.3 V for 3.3-V supply and
1.5 V to 5 V for 5-V supply adjustable regulator. The board also provides the ability to separate the
PSoC core VDD rail into two separate rails, analog and digital. In addition, the board is able to
separate the I/O VDD rails, giving the flexibility to power the I/O ports at different voltages.
The board is equipped with a 2×16 alphanumeric LCD module capable of 1.8 V to 5.0 V I/O. In
addition, there is a mini-B full-speed USB interface and a female DB9 serial communications
interface. Also included is a 12-pin wireless radio module interface, which can be used to develop
CyFi™ low-power RF or other embedded RF solutions with this kit. The board also has a prototyping
area containing a small breadboard, complete with I/O port sockets nearby, multipurpose LEDs,
mechanical push buttons, and a multipurpose variable resistor. In addition, three capacitive sensing
elements (two buttons and a five segment slider) are included on the board to allow the evaluation of
CapSense®applications.
The board has four general-purpose I/O (GPIO) expansion slots, allowing the I/O to expand to exter-
nal boards.
The board is designed with modularity in mind and, as a result, supports removable processor mod-
ules. This allows you to plug different PSoC processor modules into the board based upon the
desired features of both 8-bit and 32-bit PSoC devices.
Note
■The PSoC device may get hot or damaged if many I/O pins are configured as strong drive with
initial state HIGH and grounded externally using wires.
■The PSoC device may get hot or damaged if many I/O pins are configured as strong drive with
initial state LOW and connected to Vcc externally using wires.
1.4.1 Default Switch and Jumper Settings
Jumpers on the CY8CKIT-001 PSoC development board have a default setting to operate at 3.3 V.
For default configuration, each of the jumpers must be set according to these instructions.
Note All CY8C28 and CY8C29 family processor module code examples are configured for 5 V. Con-
figure the board to 5 V, before creating the code examples.

2. Loading My First PSoC Project
The CY8CKIT-001 PSoC Development Kit supports projects across the PSoC 1, PSoC 3, and
PSoC 5 architectures. This section walks you through the high-level design process for opening,
building, programming, and running your first PSoC project using this kit.
Before beginning, follow each of these steps to make certain that your software and hardware
environments are properly configured and ready for these projects:
1. Install PSoC Designer using the steps listed in Installing PSoC 1 Development Software on
page 8.
2. Install PSoC Creator using the steps listed in Installing PSoC 3 Development Software on page 8.
3. Connect the MiniProg3 into your PC using the supplied USB cable. When you connect the
MiniProg3, Microsoft Windows®may indicate that it has found new hardware. All required drivers
are installed as part of the PSoC Programmer installation process; however, if Windows opens
the driver installation dialog boxes, accept the defaults and allow Windows to automatically find
the appropriate driver.
4. Close any open PSoC Creator or PSoC Designer applications and projects.
5. Configure the PSoC development board (jumper settings and switches) in its default configura-
tion, as described in Default Switch and Jumper Settings on page 10.
6. Use the PSoC CY8C28 family processor module or PSoC CY8C29 family processor module for
the PSoC 1 version of your first PSoC project (My First PSoC 1 (CY8C28) Project on page 16 or
My First PSoC 1 (CY8C29) Project on page 20).
7. Use the PSoC CY8C38 family processor module for the PSoC 3 version of your first PSoC
project (My First PSoC 3 (CY8C38) Project on page 25).
8. Use the PSoC CY8C55 family processor module for the PSoC 5 version of your first PSoC
project (My First PSoC 5 (CY8C55) Project on page 28).
9. For a PSoC 1 project, use the ISSP header on the PSoC CY8C28 family processor module or
PSoC CY8C29 family processor module and connect the MiniProg3 ISSP port.
10.For a PSoC 3 or PSoC 5 project, use the JTAG ribbon cable. Connect the ribbon cable to the
MiniProg3 and the CY8C38 family processor module or CY8C55 family processor module into
the header labeled PROG on the processor module.
Note The MiniProg3 should not be "hot plugged" into processor modules that are attached to the
PSoC development board. In other words, do not plug the ribbon cable of the MiniProg3 into the
processor module while code is actively running on the module. Doing so may cause the PSoC
device to unintentionally reset. Power down the PSoC development board and module by
unplugging the power supply from the development board before attaching the MiniProg3 device
to the module board. When the ribbon cable is attached to the module board, power the system
by plugging in the power supply to the PSoC development board. This will avoid any undesirable
PSoC device resets.
11.Power the PSoC development board using the 12-V AC power supply adapter.

6. In the Program Part window, click the program arrow to program the device.
7. Wait until programming is completed, to continue.
Note For debugging purposes, the CY8C28 family processor module is designed to accommodate
the use of the CY3215-DK In-Circuit Emulator (ICE-Cube). When using the ICE-Cube debugger,
make certain that PSoC Designer is configured so that the ICE-Cube does not provide power to the
processor module. Within the PSoC Designer application, select Project Settings and select
Debugger from the tree. Make sure that External only is selected under the Pod Power Source
section and select Execute Program from the Debug menu to start debugging.
Connect the processor module to the CY3215-DK ICE-Cube, as shown in Figure 2-4.

2.1.4 Running My First PSoC 1 Project
1. Connect P1[6] to LED1 and P1[7] to LED2. Verify that LED1 and LED2 are blinking based on the
project's use of the PWM and software. Now that the PSoC 1 device is programmed, reset the
PSoC development board by pressing and releasing the reset switch (SW4).
2. LED1 blinks approximately once every second and LED2 blinks about three times a second.
