Introduction 1.2 FUNCTIONAL OVERVIEW The block diagram shown in Figure 1-3 illustrates the mainstream operation of the CAN/LIN/J2602 PICtail™ (Plus) Daughter Board. The board contains two LIN signal conditioning circuits and two CAN signal conditioning circuits. The board also enables power to be provided by the development board it is connected to, or by an external 12V DC source.
CAN/LIN/J2602 PICtail™ (Plus) Daughter Board User’s Guide For PIC18 devices, the pinout for the LIN1 and LIN2 modules can be different. The jumpers J4, J8, J13 and J14 are for choosing between these pinouts. For the specific pinout that is necessary for the PIC18 that is used, refer to that device’s data sheet. For PIC24 and dsPIC33 devices, make sure to leave the J4, J8, J13 and J14 jumpers disconnected. Otherwise, these connections can disrupt LIN communications.
CAN/LIN/J2602 PICtail™ (Plus) DAUGHTER BOARD USER’S GUIDE Chapter 2. Hardware This chapter provides a functional overview of the CAN/LIN/J2602 PICtail (Plus) Daughter Board and identifies the major hardware components. Topics covered include: • Board Setup • Hardware Components 2.1 BOARD SETUP Figure 2-1 is a photograph of the CAN/LIN/J2602 PICtail (Plus) Daughter Board. Callouts indicate the CAN bus, LIN bus and signal connections on the daughter board.
CAN/LIN/J2602 PICtail™ (Plus) Daughter Board User’s Guide 2.2 HARDWARE COMPONENTS Figure 2-2 identifies the key hardware components on the CAN/LIN/J2602 PICtail (Plus) Daughter Board.
Hardware 2.2.1 Explorer 16 Board PICtail™ Connector (J7) Explorer 16 Board PICtail connector J7 (see Reference 1), a 120-pin signal connector that carries signals from the I/O pins of the dsPIC33F or PIC24 device on the Explorer 16 Board to the CAN/LIN/J2602 PICtail (Plus) Daughter Board. This connector handles the following signals: • 9V, 5V and 3.
CAN/LIN/J2602 PICtail™ (Plus) Daughter Board User’s Guide 2.2.8 CAN Transceivers (U3, U4) A pair of MCP2551 CAN transceivers (see Reference 11 and Reference 14) provide the interface between the ECAN modules on the dsPIC33F, PIC24 or PIC18 control device and the CAN bus. The transceiver converts the signals from the ECAN modules on the dsPIC33F, PIC24 or PIC18 device to a pair of differential CAN bus signals. 2.2.
Hardware 2.3 AUXILIARY HEADER PINOUTS The two auxiliary headers, J17 and J18, allow for monitoring and debugging other pins from the microcontroller as well as the CAN and LIN pins. Depending on which development board is being used, the auxiliary headers have different pinouts. Table 2-1 maps out microcontroller pins to header pins for both development boards, the PIC18 Explorer Board and the Explorer 16 Board. Refer to Figure A-4 for the schematic of the headers.
