Safety Information
Regulatory Compliance
The CY8CKIT-017 is intended for use as a development platform for hardware or software in a
laboratory environment. The board is an open system design, which does not include a shielded
enclosure. This may cause interference to other electrical or electronic devices in close proximity.
In a domestic environment, this product may cause radio interference. In this case, the user may be
required to take adequate prevention measures. Also, the board should not be used near any
medical equipment or RF devices.
Attaching additional wiring to this product or modifying the product operation from the factory default
may affect its performance and cause interference with other apparatus in the immediate vicinity. If
such interference is detected, suitable mitigating measures should be taken.
The CY8CKIT-017 as shipped from the factory has been verified to meet with requirements of CE as
a Class A product.
The CY8CKIT-017 contains electrostatic discharge (ESD) sensitive
devices. Electrostatic charges readily accumulate on the human body
and any equipment, and can discharge without detection. Permanent
damage may occur on devices subjected to high-energy discharges.
Proper ESD precautions are recommended to avoid performance
degradation or loss of functionality. Store unused CY8CKIT-017
boards in the protective shipping package.
End-of-Life/Product Recycling
The end of life for this kit is five years from the date of manufacture,
mentioned on the back of the box. Contact your nearest recycler for
information on how to disposition the kit.

Safety Information
General Safety Instructions
ESD Protection
ESD can damage boards and associated components. Cypress recommends that you perform
procedures only at an ESD workstation. If one is not available, use appropriate ESD protection by
wearing an antistatic wrist strap attached to chassis ground (any unpainted metal surface) on your
board when handling parts.
Handling Boards
CY8CKIT-017 boards are sensitive to ESD. Hold the board only by its edges. After removing the
board from its box, place it on a grounded, static free surface. Use a conductive foam pad if
available. Do not slide board over any surface.

CY8CKIT-017 CAN/LIN Expansion Board Kit Guide, Doc. # 001-57814 Rev. *D 7
1. Introduction
The CY8CKIT-017 CAN/LIN Expansion Board Kit (EBK) is an expansion board that is used with the
CY8CKIT-001 PSoC®Development Kit (DVK) or the CY8CKIT-030 PSoC 3 Development Kit (DVK).
It enables you to evaluate the Controller Area Network (CAN) and Local Interconnect Network (LIN)
slave communication capability of PSoC 3 and PSoC 5 devices. You can design your own projects
with an easy-to-use CAN and LIN slave components in Cypress's PSoC Creator™ software, or by
altering code examples provided with this kit.
1.1 Kit Contents
This kit contains:
■CAN/LIN expansion board
■Quick start guide
■Kit CD
Inspect the contents of the kit; if anything is missing, visit http://www.cypress.com/?rID=40215 or
contact Cypress Technical Support.
1.2 Kit Compatibility
This kit contains an expansion board and requires other Cypress kits to use it. It is designed to add
CAN and LIN capabilities to the CY8CKIT-001 PSoC Development Kit (DVK). This DVK supports
PSoC 1, PSoC 3, and PSoC 5 families. However, it may be necessary to obtain or purchase
additional processor modules for the CY8CKIT-001 to develop applications for a particular PSoC
device family.
This kit is also compatible with the CY8CKIT-030 PSoC 3 Development Kit. The EBK can be
attached to port E of the CY8CKIT-030 DVK. A CY8CKIT-030 kit can generally be substituted for a
CY8CKIT-001 kit when using the CY8CKIT-017 kit. Therefore, any information regarding the
CY8CKIT-001 kit in this document generally applies to the CY8CKIT-030 kit as well.
The CY8CKIT-017 can also interface with the CY3280-22x45 Universal CapSense Controller (UCC)
kit for CY8C2xx45 PSoC 1 devices. This EBK can add LIN capabilities to the UCC kit. However, it
does not add CAN capabilities to this kit, because PSoC 1 devices do not have CAN hardware.
CAN and LIN are communication protocols and require more than one CAN or LIN node to set up
communication between nodes. Therefore, it is recommended to have two CY8CKIT-001 DVKs and
two CY8CKIT-017 EBKs. This enables you to set up CAN or LIN communication between two CAN
or LIN nodes. An alternative recommendation is to have a CAN or LIN bus emulator or analyzer. This
enables you to emulate a CAN or LIN node to communicate with a PSoC CAN or LIN controller. See
sections Using a CAN Bus Analyzer Tool on page 22 and Using a LIN Bus Analyzer Tool on page 22
for more details on using a CAN analyzer or LIN analyzer tool with this kit.

1.3 PSoC Creator
Cypress' PSoC Creator software is a state-of-the-art, easy-to-use software Integrated Development
Environment (IDE). It introduces a hardware and software co-design environment based on classical
schematic entry and revolutionary embedded design methods.
With PSoC Creator, you can:
■Create and share user defined, custom peripherals using hierarchical schematic design.
■Automatically place and route select components and integrate simple glue logic that is normally
present in discrete muxes.
■Trade-off hardware and software design considerations allowing you to focus on what matters
and get to market faster.
PSoC Creator also enables you to tap into an entire tools ecosystem with integrated compiler tool
chains, RTOS solutions, and production programmers to support both PSoC 3 and PSoC 5.
1.4 Getting Started
To get started, see the Kit Operation chapter on page 13 for a description of the kit operation and
how to program the PSoC 3 device. Code examples are used to explain how to use the CAN/LIN
expansion board with the CY8CKIT-001 DVK. The Hardware chapter on page 23 provides details of
the expansion board hardware. The Code Examples chapter on page 31 guides you to create simple
code examples. The Appendix chapter on page 61 provides the schematics and bill of materials
(BOM) associated with the expansion board.

b. Connect a CAN analyzer to P2 of the EBK.
4. For the LIN example test, connect VCC, LIN bus, and GND of the LIN analyzer to connector P5
of the EBK.

CY8CKIT-017 CAN/LIN Expansion Board Kit Guide, Doc. # 001-57814 Rev. *D 13
3. Kit Operation
3.1 Introduction
The CY8CKIT-017 CAN/LIN EBK includes two CAN code examples and one LIN code example. The
CAN code examples demonstrate two-way CAN communication between two PSoC 3 CAN
controller nodes on a CAN bus. These examples must be downloaded into two separate PSoC 3
devices.
■Code Example 1: CAN_Example_1
This project demonstrates sending and receiving of CAN messages. The project sends an 8-bit
value on the CAN bus and also receives an 8-bit value from the CAN bus.
■Code Example 2: CAN_Example_2
This project is identical to the 'CAN_Example_1' project, except the CAN message IDs are
reversed. Therefore, this project implements a CAN node that can communicate with a PSoC 3
that is programmed with the 'CAN_Example_1' project. See Code Examples on page 31 for more
information.
Note Most of the information related to CAN code examples describes kit operation when two
CYC8KIT-001 DVKs and two CY8CKIT-017 EBKs are available. If only one CY8CKIT-001 DVK
and one CY8CKIT-017 EBK are available, see Using a CAN Bus Analyzer Tool on page 22 for
information on alternative ways of using this kit.
■Code Example 3: LIN_Example
This project demonstrates the LIN slave functionality of PSoC 3. It receives an unconditional
frame having eight bytes of data from the LIN bus with frame ID 0x10. The eight bytes are: Byte 1
is the scalar signal of 7-bit length and Byte 2 to 8 are the byte array signal of 7-byte length. This
is written to another unconditional frame. The LIN master can read back the data by sending the
frame ID 0x11.
Because the LIN master component is not yet available with PSoC 3, a LIN analyzer is required
to test this project. See Using a LIN Bus Analyzer Tool on page 22 for more information.
3.2 Programming PSoC 3 Device
The code examples are provided on the Start Page of PSoC Creator after the CY8CKIT-017 kit
contents are installed. This section provides details on programming the PSoC 3 device.
To program the ‘CAN_Example_1’ project to the PSoC 3 silicon, follow these steps:
1. Place the PSoC 3 processor module on the CY8CKIT-001 DVK.
2. Power the DVK using either battery connections or a wall power unit.
3. Connect the MiniProg3 JTAG cable to the JTAG connector, both on MiniProg3 and the PSoC 3
processor module. Connect the MiniProg3 to a host PC USB high speed port using a USB cable.
The connections for steps 1 to 3 are shown in Figure 3-1.
