then record the signal seen by the USRP2

middle, not at the edges

we use red already on atusb itself
- atusb-pgm.brd: arranged references and component values for better
visualization and proper silk screen
- atusb-pgm.sch, atusb-pgm.brd: updated version number (version on the
board itself didn't change, because the traces/pads layout is the

- atben.sch, atben.cmp, atben.brd: CLKM test point would have been
inaccessible - reduced its size and moved it closer to the transceiver

analog power and crystal

larger

corner

neither Atmel not Wuerth have it; in experiments, no effect was
observed)

- atben.brd: aligned 8:10 card shape and antenna to metric (0.1 mm) grid
and adjusted outline accordingly

"const"

and include version.h instead
- usb2/: renamed to usb/

FreakUSB
- Makefile: changed vpath from usb2/ to usb/
- Makefile (CFLAGS): changed include from -Iusb2 to -Iusb

- 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
- include/atrf.h (atrf_set_clkm), lib/atrf.c (atrf_set_clkm): set or
disable CLKM
- lib/driver.h (atrf_set_clkm_generic), lib/atrf.c (atrf_set_clkm_generic):
generic function to set CLKM without restrictions
- lib/driver.h (struct atrf_driver): added driver operation "set_clkm"
to set CLKM
- lib/atusb.c (atusb_set_clkm, atusb_driver): restrict CLKM on ATmega32U2
boards
- atrf-txrx/atrf-txrx.c (init_txrx): use atrf_set_clkm to set CLKM
- atrf-txrx/atrf-txrx.c (init_txrx, main): pass CLKM frequency in MHz
instead of code point
- atrf.c (struct atrf_dsc): added field "chip_id" to cache chip ID
- atrf.c (identify, atrf_identify): moved identification logic to new
function
- atrf.c (atrf_open, atrf_identify): cache chip ID when opening the
device and return ID from cache
- 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 (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
