- fw/Makefile: replaced "make" with $(MAKE) (just for style) - common/Makefile.common: Makefile settings shared within project. For now, this contains only the board version, which defaults to 2010-12-16. - fw/common/Makefile, fw/boot/Makefile, fw/atusb/Makefile: include common/Makefile.common - fw/common/Makefile, fw/boot/Makefile, fw/atusb/Makefile: pass board version to cpp and gcc - fw/atusb/atusb.c (init_io): individually set IRQ_RF to one, LED and TST to zero - fw/atusb/atusb.c (init_io): added macros to set all unused pins to zero in a way that doesn't need updating if a signal moves from one pin to another - include/atusb/ep0.h: added hardware type 1 (2010-12-16 design) - common/config.h: set hardware type depending on board version - common/io.h: assign pins depending on board version
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.
