USB Interface
With the demise of the serial port, any application that
requires a connection with a personal computer has now
to be routed to the USB port. Some innovative lighting
applications occasionally require such a connection to be
established. Several models of PIC18F microcontrollers
incorporate a complete USB interface. Several interface
examples are offered to the designer to simplify the
transition from serial port to USB and to integrate the
application with existing Microsoft Windows® drivers.

Ethernet Interface
Ethernet connectivity is becoming ubiquitous and most new
office and industrial building are being wired for Ethernet. As
lower cost solutions are becoming available it is increasingly
tempting to use Ethernet for even the simplest control and
diagnostic applications.
Microchip addresses the growing demand for a small
and low-cost embedded Ethernet solution by offering the
following:

CAN and LIN Protocols
Both the CAN and LIN protocols were originally created
for the automotive market. CAN was designed as a high
reliability and speed protocol (up to 1 Mbit/s) for the harsh
environment of the car electrical bus. LIN was later added
as a simple low cost alternative for the control of non-critical
modules on a vehicle. Both find occasional applications in
lighting.
Many of the PIC18F, PIC24H, PIC32 microcontrollers and
dsPIC DSCs include a complete CAN serial interface. The
MCP25XX series of peripheral interfaces includes several
CAN transceiver and CAN I/O expander devices.
All PIC microcontroller devices offering an EUSART module
(PIC18F devices and most recent PIC16F devices) offer
direct support for LIN bus connectivity with auto-baud rate
detection and specific low power features.
Automotive Ambient Lighting Module
Reference Design
a LIN bus. These modules are offered in a very compact
form-factor board and are comprised of a PIC12F615 MCU,
an MCP2021 LIN transceiver/voltage regulator, and RGB
LED. LIN commands are interpreted by the module to control
color mixing (16,383 colors) and intensity (1023 levels).
The kit ships with 4 modules to assign as lighting zones in
a LIN or J2602 network. These modules can also be used in
conjunction with the APGDT001 LIN Serial Analyzer to quickly
create a working LIN network straight out of the box.
