- gui.c (area_off, gui): don't show a regulation area by default
- letter.h, letter.c: drawing of limited character set
- Makefile (OBJS_host, OBJS_ben_jlime): added letter.o
- gui.c (print, area_selector, gui): show regulation area selector
- gui.c (wlan_area): the currently displayed regulation domain
- gui.c (wlan_channels): return the number of WLAN channels
- gui.c (show_wlan_channel): determine whether the specified channel
should be used in the currently displayed regulation domain
- gui.c (label_wlan_channels): show WLAN channel numbers and their
width
- gui.c (gui): switch regulation domain with E (Europe), J (Japan),
and U (US)
- gui.c (gui): quit now only if Q is pressed instead of any key
- gui.c (gui): call label_wlan_channels to display the WLAN channels
- atrf-xmit.c (xfer_one): wait 10 ms for the packet to be sent (1 ms
was clearly too short)
- atrf-xmit.c (xfer_one): use wait_for_interrupt instead of
atrf_interrupt_wait, so that the retry logic can do its work
- atusb-common.c (atusb_interrupt_wait): the atusb firmware no longer
reads and accumulates IRQs for us. We now just wait for the
notification, then read IRQ_STATUS. Let higher layers take care of
retries and all that.
- atusb-common.c (atusb_open): clear any pending interrupts
- board_app.c (INT0_vect): always read IRQ_STATUS, even if an
interrupt is already enqueued
- board_app.c (INT0_vect): if an interrupt is enqueued, accumulate
the interrupts signaled since
- board_app.c (irqs_more): when a pending transfer completes, send
interrupts accumulated since (if any)
- board.h (gpio_cleanup), board_app.c (gpio_cleanup): restore INT0
when done manipulating GPIOs
- board.c (gpio): updated comment explaining how to restore INT0
- include/atusb/ep0.h (enum atspi_requests), ep0.c
(ATUSB_GPIO_CLEANUP): new request to return to normal operation
after ATUSB_GPIO
ausb_bulk_read may lose data when timing out. We therefore try to
minimize the number of times we time out. Reading until no more
interrupts arrive may have looked like a good idea, but it just
causes trouble for now.
- lib/atrf.c (atrf_interrupt_wait): interrupt_wait is no longer
optional
- atrf-proxy/atrf-proxy.c (cmd_more): we no longer need to handle
atrf_interrupt_wait being unsupported
- lib/atusb-common.c (atusb_interrupt_wait): clarify what we don't
want to return -1 on error
Since GPIO manipulations may cause stray INT0 activity, we turn off
INT0 handing on ATUSB_GPIO. The MCU must be reset to restore access
to INT0.
There are still issues to resolve with the GPIO test. It may turn
out that there's a less invasive solution than just turning off
INT0 completely.
- board_app.c (gpio): mask INT0 before manipulating GPIOs
- board_app.c (board_app_init): make it clearer that EIMSK is a bit
mask
- atrf-xmit.c (xfer_one): use atrf_interrupt_wait instead of
atrf_interrupt to pull the interrupt line
- atrf-xmit.c (xfer_one): removed delay-based wait to interrupt
- atrf-xmit.c (xfer_one): use atrf_interrupt_wait instead of reading
REG_IRQ_STATUS directly
- include/misctxrx.h (wait_for_interrupt), lib/misctxrx.c
(wait_for_interrupt): replaced sleep_us*timeout limiting mechanism
with a single timeout value in milliseconds
- lib/misctxrx.c (wait_for_interrupt): use atrf_interrupt_wait instead
of polling
- lib/misctxrx.c (wait_for_interrupt): cleaned up control flow
- lib/misctxrx.c (run, die, wait_for_interrupt): renamed variable "run"
to more specific "sigint"
- atrf-txrx/atrf-txrx.c (ping_rx, ping): pass timeout in milliseconds,
not deciseconds
- atrf-rssi/atrf-rssi.c (sweep), atrf-rssi/gui.c (sweep),
atrf-txrx/atrf-txrx.c (init_txrx, receive_message, receive_pcap,
receive, transmit, transmit_pattern, ping_tx, ping_rx),
atrf-xmit/atrf-xmit.c (init_tx, init_rx, xfer_one),
lib/cwtest.c (enter_test_mode_230, start_test_mode_231):
updated use of wait_for_interrupt
- atben.c (atben_interrupt_wait): loop until either the timeout has
been reached or an interrupt has occurred
- atben.c (atben_driver): added atben_interrupt_wait
- atusb-common.c (atusb_open): claim interface, so that we can do bulk
I/O without complaints from the kernel
- atusb-common.h (atusb_interrupt_wait), atusb-common.c: blocking read
for interrupt status byte on EP1
- atusb.c (atusb_driver), atusb-spi.c (atusb_spi_driver): provide the
interrupt_wait operation
- tools/lib/driver.h (struct atrf_driver): new driver operation
interrupt_wait
- include/atrf.h (atrf_interrupt_wait), atrf.c: new function to
wait for a transceiver interrupt without polling
- board.h (board_app_init), board_app.c (board_app_init): new function
for application-specific board initialization
- atusb.c (main): call board_app_init
- board_app.c (INT0_vect): on RF interrupt, read REG_IRQ_STATUS and
send the status byte on EP1
- board_app.c (board_app_init): set up interrupt on rising edge of
INT0 (INT_RF)
- descr.c (config_descriptor): added EP1 as bulk IN
The code is quite special-cased. Some more changes will be necessary
for interrupt or OUT EPs.
- atu2.c (NUM_EPS): increased from 1 to 2
- atu2.c (ep_rx): send zero-length packet also for EPs != 0
- atu2.c (handle_ep): clear FIFOCON when sending data on EP != 0
- atu2.c (ep_init): configure EP 1 as bulk IN with size 64
- usb.c (NUM_EPS): we don't need to define NUM_EPS here
- ep0.c (setup_request): store combined request code in "req", for
later reuse
- include/ep0.h (ATUSB_SPI_WRITE, ATUSB_SPI_READ1, ATUSB_SPI_READ2),
ep0.c (setup_request): new requests that translate easily into
general SPI operations
- dirtpan.c: changed control byte from innovative 7 bit layout to the
more common 8 bits. My, haven't we had our morning coffee yet ?
- dirtpan.c: added explanation that the two highest bits of the
control byte have to be zero, to avoid conflicting with RFC4944
With warnings treated as errors I get this:
In file included from flash.c:19:0:
usb/dfu.h:107:35: error: 'struct setup_request' declared inside parameter list
usb/dfu.h:107:35: error: its scope is only this definition or declaration, which
is probably not what you want
make: *** [flash.o] Error 1
Struct setup_request is declared in usb.h so include it.

- include/cwtest.h (cw_test_needs_reset), lib/cwtest.c
(cw_test_needs_reset): new function to indicate all cases where the
transceiver needs to be reset (instead of using SLP_TR)
- lib/cwtest.c (cw_test_end): use cw_test_needs_reset instead of
open-coding the decision
- lib/cwtest.c (enter_test_mode_230, start_test_mode_231): always wait
for the PLL to lock. Contrary to the assumption in the previous
commit, we should always see this interrupt.
- atrf-path/atrf-path.c (sample): initialize the transceiver if we had
to reset it
- atrf-path/atrf-path.c (sample), atrf-path/atrf-path.c (do_half_sweep):
moved the tTR19 delay to "sweep", so that all branches share it and it
is taken only once
We seem to have a path where the PLL is already locked when we get
there. We thus never get an interrupt and hang.
Pending further investigation, just use a timeout that is longer
than the worst-case PLL lock time.
The explanation is simple: reset from any state but P_ON throws us
back into TRX_OFF, not P_ON. That's why the P_ON test only worked
predictably after power-cycling the board.
- prod/atusb (gpio_usb): removed P_ON test
- prod/atben (gpio_ben): added comment to P_ON test explaining why
it works in this case
