  • Page 5: Introduction

    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), the CY8CKIT-030 PSoC 3 Development Kit (DVK), or the CY3280-22X45 Universal CapSense Controller (UCC) kit. It enables you to evaluate the Controller Area Network (CAN) communication capability of PSoC 3 and PSoC 5 devices.

    LIN node in order to set up communication between nodes. Therefore, it is recommended to have two CY8CKIT-001 DVK kits and two CY8CKIT-017 EBK kits. This enables you to setup CAN or LIN communication between two CAN or LIN nodes. An alternate recommendation is to have a CAN or LIN bus emulator or analyzer.

    VIN power supply of the DVK. One reason to use this would be if there are two CY8CKIT-001 boards (both with CY8CKIT-017 EBKs) that are connected to each other between their CAN connectors or LIN connectors. In this case, it is useful to allow the VIN power supply of one DVK to power up the other DVK (and its EBK) through the LIN or CAN header.

    Hardware Default Switch and Jumper Settings Jumpers on the CY8CKIT-017 CAN/LIN Expansion Board have a default setting for 5V operation. For Default configuration, each of the jumpers must be set according to these instructions (any jump- ers on the board not mentioned below should have no jumper installed).

    Example Projects The CAN_Example_1 project demonstrates the implementation of a CAN node using a CY8CKIT- 001 DVK, a CY8CKIT-009 PSoC 3 processor module, and a CY8CKIT-017 CAN/LIN EBK. The test setup shown in Figure 3-9 on page 15 consists of two CAN nodes, created using two CY8CKIT-001 DVKs, two CY8CKIT-009 PSoC 3 processor modules, and two CY8CKIT-017 CAN/LIN EBKs con- nected by a DB9 cable.
