FreakUSB
- Makefile: changed vpath from usb2/ to usb/

- atusb.brd: rearranged component references and values for
printing/display
- atusb.brd: bumped version to 20110214
- usb.sch (R1): changed from 68 Ohm to 180 Ohm, to decrease BOM size
- atrf.sch (C17): changed from 1 pF to 2.2 pF (value is more common,
and it can only help to reduce harmonics)
- atusb.sch, usb.sch, atrf.sch: bumped version to 20110214
- atusb.cmp: updated
The Makefile didn't see the FreakUSB object files at the expected place,
so it always rebuild them.
- Makefile (USB_OBJS): removed paths from object file names
- Makefile: added vpaths for the FreakUSB source file locations
- Makefile (atusb.elf, clean): we no longer need $(notdir ...) for the
object files
- atusb.c (main), board.h (board_init), board.c (board_init): moved
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
- spi.c (spi_init): set nSS to 1 before enabling the output, so that we
don't generate what looks like an empty SPI transaction
- atusb.brd: moved C14 and adjacent via 10 mil away from the transceive,
for improved solderability
- atusb.brd: moved nRST_RF via and trace by 5 mil, for better access to
the trace
- atusb.brd: reduced crystal front ground zone such that it does not
creep under XTAL2 corner (where it might meet exposed metal)
- board.h (read_irq), board.c: return status of the RF IRQ
- 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
- 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)
