The Makefile didn't see the FreakUSB object files at the expected place,
so it always rebuild them.
- Makefile (USB_OBJS): removed paths from object file names
- Makefile: added vpaths for the FreakUSB source file locations
- Makefile (atusb.elf, clean): we no longer need $(notdir ...) for the
object files
- atusb.c (main), board.h (board_init), board.c (board_init): moved
clock and I/O initialization to board file
- board.h (led), board.c (led), atusb.c (main): abstracted LED setting
in function "led" instead of open-coding it
- spi.c (spi_init): set nSS to 1 before enabling the output, so that we
don't generate what looks like an empty SPI transaction
- board.h (read_irq), board.c: return status of the RF IRQ
- board.h (PIN, PIN_1, PIN_2): macros to read port pins
- ep0.c (my_setup): make ATUSB_POLL_INT return the real interrupt
- fw/include/atusb/ep0.h (HW_TYPE_110131): defined hardware type 2 for
ATmega32U2-based boards
- fw/ep0.c: define HW_TYPE as HW_TYPE_110131, not directly as 2
- fw2/atusb.c: include atusb/ep0.h instead of declaring ep0_init locally
- io.h: renamed to board.h
- Makefile (OBJS): added board.o
- atusb.c (reset_rf): moved to board.c
- board.h (reset_rf): give reset_rf a proper declaration
- atusb.c, ep.c, spi.c: include board.h instead of io.h
- ep0.c (do_usb_recv, usb_recv): implemented creepy buffer reception
- ep0.c (my_setup): added dummy for ATUSB_POLL_INT (always return 0)
- ep0.c (my_setup): send a zero-length packet at the end of
ATUSB_RF_RESET and ATUSB_REG_WRITE to indicate status stage
- Makefile (OBJS): added spi.o
- spi.h, spi.c, atusb.c: moved SPI functions to new file
- spi.h (spi), spi.c (spi), atusb.c (main): renamed function "spi" to
"spi_io"
- atusb.c (reset_rf, main): moved transceiver reset to separate function
- ./: basic framework to build a firmware that can enumerate
- usb/patches/: patches to make FreakUSB 0.7 compile cleanly and to make
it work in our context
