- tools/lib/atusd.c (spi_send_partial, spi_send): removed the old spi_send and renamed spi_send_partial to spi_send - tools/lib/atusd.c (atusd_cycle, spi_send, spi_recv, atusd_open): updated for removal of SLP_TR and split of MxSx into MOSI and MISO - tools/lib/atusd.c (atusd_reset_rf, atusd_open): added delays to precharge the capacitors - tools/lib/atusd.c (atusd_reset, spi_data_in, spi_data_out, spi_finish): removed functions for obsolete hardware features - tools/lib/atusd.c (atusd_reg_read): removed calls to removed functions - tools/lib/atusd.c (atusd_buf_write, atusd_buf_read, atusd_driver): new buffer read/write functions - tools/atspi-txrx/atspi-txrx.c (init_txrx): set the internal osciallator trim only in the USB version. Switch to the external oscillator in the uSD version. - tools/atspi-rssi/atspi-rssi.c (sweep), tools/atspi-txrx/atspi-txrx.c (set_channel): wait for the PLL to settle after setting the channel - tools/include/atspi.h, tools/lib/atspi.c (atspi_interrupt), tools/lib/driver.h (struct atspi_driver), tools/lib/atusd.c (atusd_interrupt): new function to poll the interrupt line - tools/atspi-txrx/atspi-txrx.c (receive): only read REG_IRQ_STATUS if there is a pending interrupt - tools/atspi-id/atspi-id.c (usage): print "usage:" as well - tools/Makefile (upload): upload the atspi tools to the Ben |

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.
