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.
- atusb.c (main), board.c (reset_rf): moved call to spi_init into
reset_rf
- board.c (reset_rf, board_init): moved GPIO setup to reset_rf
- board.c (reset_rf): set GPIOs to reset defaults
- board.h (gpio), board.c: read/modify/write all settings of GPIO
ports
- include/atusb/ep0.h (enum atspi_requests): added new request
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)
- Common (doit): if the environment variable LIVE is set to "true",
run the command in "script" instead of using "eval"
- Common (LIVE): unset this variable on initialization
- atusb-flash (flash): set LIVE, to obtain progress output from avrdude
- prod/atusb: added clock frequency test
- prod/doc/setup.hmac: added GSL (libgsl) build dependency
- prod/doc/setup.hmac: recommend use of NTP on the PC
- prod/doc/test.hmac: added atusb to the clock frequency section
- Makefile: removed limitation to Ben and added host build
- atusb.c: atusb-specific acquisition and calculations
- atrf-xtal.h (do_atusb): interface to atusb.c
- atrf-xtal.c (atben, atusb, main): added switch to board-specific driver
- atrf-xtal.c (usage, main): added support for atusb
- 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
This means that we only depend on f32xbase for atusb-sil (defunct) and
cntr (needs updating), but not for any of the project's main parts.
- makefiles/Makefile.basic: copied over from
f32xbase/lib/Makefile.common
- makefiles/Makefile.basic (LDLIBS): removed inclusion of libusb
- tools/Makefile.common: use makefiles/Makefile.basic
- install/INSTALL-Ben, prod/doc/setup.hmac: removed f32xbase
dependency
- test.hmac: added more details on physical test setup
- setup.hmac: described SPECTRUM_MARGIN parameter
- setup.hmac: described process for generating the reference spectrum
- gui.c (segment, draw, gui): make caller provide color, to ease sharing
- gui.c (dump, gui): moved call to print_sweep to separate function
- gui.c (DUMP_RGBA, dumps, n_dumps, dump, draw_dumps, gui): record all
dumps and display them in the background
- sweep.h (print_sweep), atrf-path.c (print_sweep): make global, for
sharing with gui.c
- gui.c (gui): dump the sweep results to standard output if "D" is
pressed
- Makefile: define driver names depending on device role
- Makefile: changed title comment to indicate that this Makefile is no
longer considered just a convenience hack
- atusb: define USB_ID via a variable instead of hard-coding it
