Page 17 Hardware CAN Physical Layer Transceiver Circuits The CY8CKIT-026 has two CAN transceivers: one is low speed (up to 125 Kbps baud rate) and fault tolerant, and the other is high speed (up to 2 Mbps baud rate). The PSoC 4M device supports two CAN modules, so these two transceivers enable you to use both of them to connect to CAN net- works.
Page 18 Hardware By default, pin 9 of the CAN connector is left floating. However, if the jumper (J13 for CAN1 transceiver and J21 for CAN2 transceiver) is populated, pin 9 of the CAN connector is connected to the VIN power rail of the Shield board. This is useful if you want to power up other CAN nodes through the CAN connector or if you want to power up the Shield board from the power supply of some other CAN node.
Page 19 Hardware 3.2.5 Choke Footprint A footprint for a common-mode signal suppression choke is available on the shield board for both the transceiver circuits, but these are not populated. These footprints can be populated with a B82789C0 (or equivalent) choke to suppress common-mode signals on the CAN bus. If a choke component is mounted on the L2 footprint (for CAN1 transceiver), resistors R29 and R35 must be removed from the board.
Page 20 Hardware CAN2_TX and CAN2_RX pins need to be connected to the CAN TX pin, CAN_RX pin of the PSoC (microcontroller) respectively, using external connecting wires. CAN2_EN pin is used enable/disable the transceiver which should be connected to the CAN_EN pin of the microcontroller. The trans- ceiver is enabled by default.
Page 21 Hardware Ensure extra care when connecting an analyzer to either of the LIN connectors. If the LIN analyzer provides 12 V supply already to its VBAT pin, remove jumper J16 for LIN1 connector and J7 for LIN2 connector or do not power the shield with external 12 V supply through the J11 and J12 connectors. Warning: Since the jumpers J16 and J7 are populated by default, ensure extra care while connecting the LIN analyzer VBAT pin to the shield kit pin.
Page 22 Hardware 3.3.3 LIN Master and Slave Configurations By default, both the LIN circuits are configured for LIN slave operation. Table 3-5 shows how each circuit is populated by default to configure it for the LIN slave mode. Table 3-5. Configuration for LIN Slave Operation (Default) Diode Resistor Capacitor...
Page 23 Hardware All three LEDs can be completely isolated from the rest of the Pioneer Kit by removing resistor R38, which is a 0 resistor. This is useful if the LEDs are not needed, but other circuits on the Shield Kit are needed.

Page 30 Kit Operation This chapter explains how to set-up the hardware connections in order to establish CAN and LIN communication using CY8CKIT-026. Default Jumper Settings on CY8CKIT-026 Table 4-1 shows the default jumper settings of the CY8CKIT-026 CAN and LIN Shield Kit. Table 4-1.
Page 31 Kit Operation Figure 4-1 shows connecting two CAN and LIN Shield kits through a DB9 cable. In this figure, the kit on the left is using CAN1 while the kit on the right is using CAN2. The other transceivers may also be used by changing the jumper wire connections and DB9 connector used.
Page 32 Kit Operation Using CAN Bus Analyzer Tool This kit functions most effectively when two CY8CKIT-44 PSoC 4M Pioneer Kits and two CY8CKIT-026 Shield Kits are available. However, it is also possible to replace one CY8CKIT-044 Pioneer Kit and one CY8CKIT-026 Shield Kit with a CAN bus analyzer or emulator tool. It is even possible to use any other CAN node to communicate with this kit.
Page 33 Kit Operation Figure 4-3. CAN Analyzer Connection to CY8CKIT-026’s CAN2 Transceiver If you use a CAN bus analyzer or emulator tool to communicate with this kit, then the tool must be set up to send and receive CAN messages (at proper intervals) with proper length and message ID and at a proper baud rate.
Page 34 Kit Operation LIN Communication Hardware Setup 1. Connect the CAN and LIN Shield Kit to the Arduino header of the CY8CKIT-044/042 Pioneer Kit, as shown in Figure 1-2. 2. Connect the LIN TX, LIN RX pins and Enable/sleep control pin (GPIO) of the controller (comes from the baseboard via the Arduino header) to LINx_TX, LINx_RX and LINx_NSLP pins (on J15 connector for LIN1 transceiver, J6 connector of LIN2 transceiver) of the LIN transceiver circuit using connecting wires.
Page 35 Kit Operation Using LIN Bus Analyzer Tool The LIN code example projects demonstrate functionality of the LIN slave device, so a LIN master device must be used. A LIN bus analyzer or emulator tool can be used as the LIN master device. It is also possible to use any other LIN master node to communicate with this example project.

Page 45 Example Projects LIN_Slave_CY8CKIT-042 5.4.1 Project Description In this example, PSoC 4200 (CY8CKIT-042) acts as a simple LIN slave. The slave monitors data that is transmitted from the LIN master (analyzer). If a predefined frame is received from the master, the slave controls the RGB LED color according to the data available in the received frame. The LIN master can get the RGB LED status by sending a frame with a predefined frame ID.
Page 46 Example Projects 5.4.3 Verify Output To verify the LIN_Slave_CY8CKIT-042 code example, perform these steps. Silicon Engines LIN/USB Data Converter is used as LIN analyzer in this example. 1. Program the CY8CKIT-042 PSoC 4 Pioneer Kit with LIN_Slave_CY8CKIT-042 example project through USB connector J10. 2.
Page 47 Example Projects 6. Add the message in the analyzer software which needs to be transmitted to the slave and send it through the analyzer, as shown in Figure 5-8. Note that the message must start with the ID. Figure 5-8. Adding and Sending Message using LIN Analyzer 7.
Page 48 Example Projects 8. If a frame with ID = 0x11 is received from the LIN Analyzer, then the slave will send the RGB LED status back to the master, as provided in Table 5-9. The message in this case only needs the message ID.
Page 49 Example Projects LIN_Slave_CY8CKIT-044 5.5.1 Project Description In this example, PSoC 4200 M (CY8CKIT-044) acts as a simple LIN slave. The slave monitors data that is transmitted from the LIN master (analyzer). If a predefined frame is received from the master, the slave controls the RGB LED color according to the data available in the received frame.
Page 50 Example Projects 5. You need to connect a 12 V supply input to the board through J11 power jack or J12 screw terminal connector, if both the analyzers DO NOT provide 12 V supply. Caution: Ensure extra care when either of the LIN analyzers provide 12 V through VBAT pin and connecting it to any of the connectors J14 and J5 and also using 12 V external supply.
Page 51 Example Projects g. The result of transmitted and received data at the LIN1 analyzer is shown in Figure 5-10. Figure 5-10. Results at LIN1 analyzer In the above figure, 'InFrame1' refers to “10 22 FF FF FF FF FF FF FF” where 10 is the frame ID and 22, FF, FF, FF, FF, FF, FF, FF are the eight data bytes.
Page 52 Example Projects b. If you are using any other analyzer, make sure that the checksum setting is selected as clas- sic checksum since LIN v1.3 specification supports only enhanced checksum (this option is not required in Silicon Engines LIN-USB converter software). c.
Page 53 Example Projects Figure 5-12, ‘InFrame2’ refers to “12 11 FF FF FF FF FF FF FF” where 12 is the frame ID and 11, FF, FF, FF, FF, FF, FF, FF are the eight data bytes. Since, the ‘InFrame2’ in LIN slave2 is configured with only 2 bytes named as InSig2 and InArraySig2, the rest of the data bytes (3 to 8) are ignored by the slave.
