clock and I/O initialization to board file
- board.h (led), board.c (led), atusb.c (main): abstracted LED setting
in function "led" instead of open-coding it

don't generate what looks like an empty SPI transaction

for improved solderability

the trace

creep under XTAL2 corner (where it might meet exposed metal)

- board.h (PIN, PIN_1, PIN_2): macros to read port pins
- ep0.c (my_setup): make ATUSB_POLL_INT return the real interrupt
- fw/include/atusb/ep0.h (HW_TYPE_110131): defined hardware type 2 for
ATmega32U2-based boards
- fw/ep0.c: define HW_TYPE as HW_TYPE_110131, not directly as 2
- fw2/atusb.c: include atusb/ep0.h instead of declaring ep0_init locally
- io.h: renamed to board.h
- Makefile (OBJS): added board.o
- atusb.c (reset_rf): moved to board.c
- board.h (reset_rf): give reset_rf a proper declaration
- atusb.c, ep.c, spi.c: include board.h instead of io.h
- ep0.c (do_usb_recv, usb_recv): implemented creepy buffer reception
- ep0.c (my_setup): added dummy for ATUSB_POLL_INT (always return 0)
- ep0.c (my_setup): send a zero-length packet at the end of
ATUSB_RF_RESET and ATUSB_REG_WRITE to indicate status stage
- Makefile (OBJS): added spi.o
- spi.h, spi.c, atusb.c: moved SPI functions to new file
- spi.h (spi), spi.c (spi), atusb.c (main): renamed function "spi" to
"spi_io"
- atusb.c (reset_rf, main): moved transceiver reset to separate function
- ./: basic framework to build a firmware that can enumerate
- usb/patches/: patches to make FreakUSB 0.7 compile cleanly and to make
it work in our context
- atben.brd: make traces inside 8:10 card slot go straight as long as
possible, to avoid shorts with exposed contacts
- atben.brd: removed "IEEE 802.15.4" and "CC-BY-SA" from copper layer
- atben.brd: reduced date code to two-digit year
- atben.brd: bumped version to 20110207
- usb.sch: cleaned up programming/auxiliary/LED signals
- usb.sch: swapped LED and nRST_RF (tracking the layout)
- atusb.brd: updated for corrected netlist
- atusb.brd: moved date code which overlapped with traces
- atusb.brd: reduced front RF and power ground zones to avoid ground
fill between transceiver pads
- atusb.brd: added ground traces around crystal to widen ground zone
- atusb.pro, atusb.cmp: updated for ATmega32U2-based design
- usb.sch: rearranged LED, nRST_RF, and SLP_TR, to make layout easier
- atusb.brd: redid layout for the ATmega32U2-based design
- usb.sch: renumbered test points for serial programming
- usb.sch: moved everything down to make room on top
- usb.sch: moved description of pad placement near the pads
- usb.sch: added footprint of U1
- atusb.pro (LibName5): changed from c8051f326 to atmega8u2
- atrf.sch: export CLKM and added filter for 8 MHz clock
- atusb.sch: connect CLK between RF and USB side
- usb.sch: changed design frim C8051F326 to ATmega32U2 (needs cleanup)
- atben.brd: updated 0805-6 footprint of the balun and rearranged its
surroundings accordingly
- atben.brd: rearranged boundary between RF and power ground zones
- atben.brd: moved vias "south" of the balun by 5 mil
- atben.brd: moved component references C10, C11, and X1 such that
they're not convered by comment lines
- atben.brd: broke up comment line "east" of X1 to avoid overlap with C10
and C11 pads
- atben.brd: shifted author's name to make crossing lines coincide with
vertical strokes in letters
Settings according to
http://www.nxp.com/documents/mounting_and_soldering/AN10365.pdf
