- 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
Some of the transceiver pull-up/downs don't seem to work as
expected. Until further analysis, we perform equivalent testing
in TRX_OFF, which only uses the MCU's pull-ups.
This saves about 2 mA, leaving about 8 mA when idle. The transceiver
should consume 0.5 mA in TRX_OFF, CLKM up to 4 mA, and the idle MCU
core 1 mA. USB current is unknown.
- boot.c (MS_TO_LOOPS): increased loop count now that we no longer
have to poll
- boot.c (main): increased delay from 2.0 s to 2.5 s, because we were
racing with a sleep(2) in dfu-util
- usb/usb.h (usb_ep_change), usb/atu2.c (usb_ep_change): new function
called by the USB stack to notify the hardware-specific driver of
an endpoint state change (EP_TX or EP_RX)
- usb/usb.c (usb_io): call usb_ep_change
- usb/atu2.c (handle_ep): mask TXINI if we have nothing to send
Note: this change surprisingly _increases_ the DFU wait in the boot
loader. Not yet sure why.
- boot.c (main): move the interrupt vectors to the boot loader
section
- atusb.c (main): move the interrupt vectors to the application
section
- boot.c (main): enable global interrupts while looping (disable
them before jumping to the application)
- board_app.c (__timer_read, timer_read): removed wrapped since
we're now always called with interrupts disabled
- usb/atu2.c (ep_init): enable endpoint interrupts
- usb/atu2.c (usb_init): enable device interrupts
- usb/atu2.c (usb_poll, USB_GEN_vect, USB_COM_vect): moved poll
loop code into separate handlers for device and endpoint
interrupts
- boot.c (main), atusb.c (main): removed call to usb_poll
The old code could accidently acknowledge interrupts that appeared
between the read and the write in UxINTx &= mask.
- atu2.c (handle_ep): writing to UEINTX implies a race-free "and"
- atu2.c (usb_poll): writing to UDINT implies a race-free "and"
- board.c (board_init), board_app.h (timer_init), board_app.c
(timer_init): moved timer initialization from board_init to
new function timer_init
- atusb.c (main): call timer_init
This allows us to do other things as well, e.g., change state.
- ep0.c (ep0_init), usb/dfu.c (dfu_init): use user_setup
- usb/atu2.c (usb_poll): no need to reset user_setup - the user's
reset function can do that
- usb/usb.h (user_setups), usb/usb.c (handle_setup): removed
user_setups
- usb/usb.h (user_set_interface), usb/usb.c (user_set_interface,
handle_setup): callback for SET_INTERFACE
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
- ep0.c (ep0_init), usb/dfu.c (dfu_init): set user_setups[0] instead
of user_setup
- usb/atu2.c (usb_poll): reset user_setup on bus reset
- usb/usb.h (user_setups), usb/usb.c (user_setups): array of
interface-specific setup functions
- usb/usb.c (handle_setup): in SET_INTERFACE, select setup function
from user_setups according to interface
- usb/usb.c (handle_setup): if user_setup is not set (e.g., the
optional SET_INTERFACE was never issued), fall back to user_setups[0]
- atrf-xmit.c (xfer_one): also check that also the sender has no
pending interrupts before we start sending
- atrf-xmit.c (xfer_one): interrupt poll loop (now disabled) checked
the sender, not the receiver. oops.
- atrf-xmit.c (xfer_one): upon reception, check that the sender has
finished (IRQ_TRX_END) as well
- 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

This way, we can also spot issues in the digital interface leading to
mis-configurations. E.g., this one would be a defective SLP_TR line
in atusb:

- prod/Makefile, prod/Common: removed "-T +0.5" to use both offsets
- prod/Makefile (spectrum): print a direction indication before
running atrf-path
- gui.c (old_term, restore_term, raw, get_key): raw and non-blocking
console input
- gui,c (gui): accept console input in addition to keypressed in the
SDL window
- atrf-gpio.c (usage): added newline after synopsis
- atrf-gpio.c (usage): description of option -p was missing
- atrf-gpio.c (main): invocation without patterns/commands is now an
error
