ECAN/LIN PICtail
The block diagram shown in Figure 1-2 illustrates the mainstream operation of the
ECAN/LIN 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 Explorer 16 Development Board or by an external 12V DC
source.
ECAN/LIN PICtail
1.2.1
The ECAN/LIN PICtail Plus Daughter Board connects two LIN transceivers with
integrated voltage regulators to UART modules on a dsPIC33F or PIC24 control device
on the Explorer 16 board. 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. Each LIN circuit includes a Master/Slave
jumper to accommodate a Master node on the LIN bus.
For detailed information on the MCP2021-330 LIN Transceiver, refer to Microchip Data
Sheet MCP202X “LIN Transceiver with Voltage Regulator” (DS22018).
