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]
- 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
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)
- 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
- usb/usb.h (USB_LANGID_ENGLISH_US): added USB LANGID for US-English
- board.h (board_sernum), board.c (board_sernum, hex, get_sernum,
board_init): provide the board's serial number in "board_sernum"
(UTF-encoded)
- sernum.h (sernum_get_descr), sernum.c (sernum_get_descr): return
string descriptors for the serial number
- descr.c (device_descriptor), usb/dfu.c (device_descriptor):
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
versions of dfu-util request to determine the transfer size. Luckily,
they don't do this if the transfer size is given on the command line.
- usb/atu2.c (ep_init): moved before usb_poll
- usb/atu2.c (usb_poll): register bit was used as mask, not as shift

- dfu.h (flash_end_write), flash.c (flash_end_write): write any incomplete
buffer

very end, it won't erase our buffer in mid-page
- usb/dfu.c (my_setup): call flash_end_write at the end of a download
- flash.c (flash_write): we don't use eeprom_busy_wait, removed it
- flash.c (flash_write): write the page only at one place
- flash.c (flash_write): corrected the address of the page write

address in a command

and removed target-specific operations

- dfu,c (my_setup, my_descr): removed SDCC-specific hacks
