EthErnEt Pictail™ daughtEr board Part Number: AC164121 The Ethernet PICtail™ Daughter Board provides a cost-effective method of evaluating and developing Ethernet control applications. The board is designed for flexibility and can be plugged into a wide selection of Microchip’s standard PICDEM™ demonstration boards. The development board is populated with the 28-pin ENC28J60 Ethernet controller which interfaces to the RJ-45 female connector. With a standard 28-pin PICtail pin out, the board is easily interfaced to Microchip’s 8-bit demonstration boards. Features: • 10BASE-T Ethernet • RJ-45 Female Ethernet Connector • ENC28J60 Ethernet Controller with 25 MHz oscillator • 256 Kbits SPI EEPROM (25LC256) for storing web pages and configurations • Dedicated power supply For more information, click here. 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. 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. Microchip offers a complete line of products to meet the needs of highperformance embedded applications using the CAN protocol, including 8-bit microcontrollers and 16-bit digital signal controllers (DSCs) with integrated CAN, stand-alone CAN controllers, CAN I/O expanders and CAN transceivers. All PIC microcontroller devices offering an EUSART module offer direct support for LIN bus connectivity with auto-baud rate detection and specific low power features. In addition, Microchip offers a stand-alone LIN transceiver that supports that physical layer connection. ConClusion Many lighting applications require some form of communication for remote control but also for diagnostic purposes. This article reviewed some of the advanced wired and wireless communication interfaces currently being evaluated for various lighting applications including ZigBee, MiWi, Ethernet, USB, CAN and LIN.
