2.2.4
The board has a MCP2021 High-Speed LIN Transceiver, which is connected to the
dsPIC33F device through jumpers JP4 and JP5. The LIN transceiver monitors the LIN
bus, conditions the incoming signal, and passes it to the UART module on the control
device. The LIN transceiver responds to a “Transmit Enable” from the control device by
conditioning an output signal and placing it on the LIN bus. A power-down mode turns
the transmitter and voltage regulator off, leaving only the receiver and wake-up circuits
in operation. The LIN circuit includes a Master/Slave jumper to accommodate a Master
node on the LIN bus. For more information, refer to the data sheet, MCP202X “LIN
Transceiver with Voltage Regulator” (DS22018).
2.2.5
The board uses an on-board PIC18 interface as a bridge between the UART and USB.
The PIC18 UART pins are connected to the dsPIC33F device through jumpers JP4 and
JP5.
2.2.6
The ICD 2 Connector is an RJ11 female connector (J11) that connects the MPLAB ICD
2 In-Circuit Debugger to the dsPIC33F device for programming and debugging
purposes. The ICD 2 can be connected to the board using 6-pin ICSP connector (J12).
2.2.7
The jumper J9 is a 6-pin connector that connects the PICkit™ 2 development
programmer to the PIC18F device. The board uses the on-board PIC18 interface as a
bridge between the UART and USB. The PIC18F can be programmed for USB
communication.
2.2.8
The connector J10 is an RS-232 interface port. The board uses the UART connector
to pass the UART signals from the dsPIC33F device to the dedicated UART IC
MAX3232CUE. The output of U14 is provided to the connector J10.
2.2.9
The motor connector (J7) has 11 terminals. Table 2-6 shows the functionality of each
terminal.
