- cntr/cntr.sch: change input circuit according to ECN0006 - cntr/cntr.sch: make P2_0 yet another version ID input - cntr/cntr.cmp: surprise, this wasn't checked in either - cntr/cntr.brd: update for above changes - cntr/cntr.brd: adjust for resized USB connector - cntr/cntr.brd: top ground fill was very spotty - removed it - cntr/cntr.brd: board can now be 100 mil shorter - cntr/cam/pcb.pl: updated for new board outline |

IEEE 802.15.4 Low-Rate Wireless Personal Area Network (WPAN) ============================================================ IEEE 802.15.4 defines physical layers and a media access control for wireless networks. ZigBee and 6loWPAN are based on IEEE 802.15.4. This project aims to add experimental WPAN functionality to the Ben NanoNote, in order to permit evaluation of overall network performance and to examine possible integration into future devices. This work is licensed under the terms detailed in the file COPYING. Hardware architecture --------------------- IEEE 802.15.4 transceiver chips are available from several manufacturers, including Atmel, Freescale, and Texas Instruments. These chips are similar in size, functionality, and cost. The first prototype is based on the Atmel AT86RF230. The RF module will be physically placed on the left side of the LCD module, replacing part of the display's PCB. When installed in the Ben, the transceiver will connect directly via SPI to the Jz4720. For development, a SiLabs C8051F326 microcontroller implements a USB to SPI conversion.
