2.2.1
The dsPICDEM MCLV-2 Development Board receives the power for control circuits
and the DC bus from a +24V power supply. It is connected to the board through J2 or
BP1-BP2 points.
2.2.2
By default, jumper J6 is short, and the +24V input power supply connected to J2 or
BP1-BP2 supplies the DC bus voltage to the board.
2.2.3
The board has a MCP2551 High-Speed CAN Transceiver, which is connected to the
dsPIC DSC or PIC24 MCU through jumpers JP4 and JP5. The CAN transceiver
converts the differential signal on the CAN bus to a digital signal for the ECAN™ mod-
ule. It also converts the ECAN output digital signal to a differential signal for the CAN
bus. In Sleep mode, the CAN transmitter is turned off, and the receiver operates at a
lower current level. The control device monitors the CAN activity and switches the
transceiver back to normal operation when needed. For more information, refer to the
data sheet, MCP2551 “High-Speed CAN Transceiver” (DS21667).
2.2.4
The board has a MCP2021 High-Speed LIN Transceiver, which is connected to the
dsPIC DSC or PIC24 MCU through jumpers JP4 and JP5. The LIN transceiver
monitors the LIN bus, conditions the incoming signal, and passes it to the UART mod-
ule 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 dsPIC DSC or PIC24 MCU through
jumpers JP4 and JP5.
2.2.6
The ICD 3 connector is an RJ11 female connector (J11) that connects the MPLAB
ICD 3 In-Circuit Debugger/Emulator to the dsPIC DSC or PIC24 MCU for programming
and debugging purposes. The ICD 3 can also 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™ 3 development
programmer to the PIC18F device. The board uses the on-board PIC18 interface as a
bridge between the UART and USB. The PIC18F is 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 dsPIC DSC or PIC24 MCU to the dedicated UART
IC MAX3232CUE. The output of U14 is provided to the connector J10.
