The measured values are:
board idle, looping 9 mA
LED on + 5 mA
TX CW (+3 dBm) +14 mA
------
28 mA
======
Adding a margin of 12 mA, we get 40 mA. DFU used 30 mA so far, the
application 50 mA.
- board.h (BOARD_MAX_mA): define maximum USB bus current
- descr.c (config_descriptor), usb/dfu.c (config_descriptor):
use BOARD_MAX_mA for bMaxPower instead of hard-coding values

of user_setup
- usb/atu2.c (usb_poll): reset user_setup on bus reset

interface-specific setup functions

from user_setups according to interface

optional SET_INTERFACE was never issued), fall back to user_setups[0]
- spi.h (spi_off), spi.c: disable the UART
- spi.c (spi_initialized, spi_begin, spi_init): initialize the UART
if necessary
- board_app.c (gpio): call spi_off to disable the UART instead of
open-coding the operation
- board_app.c (gpio): don't explicitly re-enable the UART but defer it
to the next communication
The SMT fab was looking there for the positions (alas, in vain).
Seems as good a place as any.
- atusb.brd: bumped file version to 20110607 (didn't change the version
printed on the layout since the layout itself didn't change)
- atusb.brd: changed fiducials from "virtual" to "normal+insert", to
include them in the position report
- atusb.brd: renamed the fiducials to give them unique names
- Makefile: bumped fab files version to 20110607
reset_rf now resets all GPIOs to their default state. This way, we
can easily recover from an incomplete or incorrect use of ATUSB_GPIO.

reset_rf
- board.c (reset_rf, board_init): moved GPIO setup to reset_rf

ports

ATUSB_GPIO
- ep0.c (my_setup): ATUSB_GPIO reads/reconfigures a GPIO port
- ep0.c (my_setup): ATUSB_SRAM_READ is FROM_DEV, not TO_DEV
- ep0.c (my_setup): in ATUSB_SRAM_READ, write setup->wLength bytes,
not "size" (which is uninitialized)
- atusb.c (main): poll the 16 bit timer for overflows
- board.h (timer_poll, timer_read), (board.c (timer_h, timer_poll,
timer_read, board_init): added support for a free-running 48 bit timer
(16 bits in hardware, 32 bits in software)
- include/atusb/ep0.h (ATUSB_TIMER), ep0.c (my_setup): new request
ATUSB_TIMER to retrieve the value of the 8 MHz counter
- include/atusb/ep0.h (enum atspi_requests): describe what the groups
of requests do

swapped in the layout. Swapped them in the schematics to match the
layout.

set iSerialNumber if serial number is available
- atusb.c (main), usb/dfu.c (my_descr): call sernum_get_descr for
unknown descriptors
- Makefile (OBJS, BOOT_OBJS): added sernum.o
What caused the error that looked like a problem with the functional
descriptor was in fact the boot loader resetting between the bus scan
and retrieval of the descriptor.
- board.c (board_init): disable the watchdog timer (tricky !)
- board.h (reset_cpu), board.c: enable the watchdog timer to cause a
CPU reset
- ep0.c (my_setup): uncommented and updated ATUSB_RESET handler
We currently don't provide the DFU Functional Descriptor, which modern

they don't do this if the transfer size is given on the command line.
