* Slightly improve and generify the USB infrastructure.Marti Bolivar2012-06-031-762/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The good news is that <libmaple/usb.h> and <libmaple/usb_cdcacm.h> did turn out generic enough in what they specify to go on unchanged. However, we can't just go on assuming that there's USB just because we're on an F1. Now that there's value line in the tree, we need to be more careful (value line F1s don't have USB peripherals). To that end, make all the F1 board-includes/*.mk files specify what line their MCU is with an MCU_F1_LINE variable. Use that to hack libmaple/usb/rules.mk so we only try to build the USB module under appropriate circumstances. While we're at it, add a vector_symbols.inc for value line MCUs under support/ld/. We need this to get the target-config.mk modifications implied by the addition of MCU_F1_LINE. We'll fix up some other performance-line-isms under libmaple/stm32f1 in a separate commit. Also in libmaple/usb/: - Move everything into a new stm32f1 directory. Due to aforementioned rules.mk hacks, there is no immediate need for an stm32f2 directory (USB support doesn't exist there). - Update the README for style and content.

* Fix a bunch of Doxygen file-level comments.Marti Bolivar2012-05-081-3/+5
| | | | | | | | | | | | | Fix @file in many places. Also fix up the descriptions where it's appropriate. This standardizes the @file formatting across the library to explicitly include any parent directories up to the repository root. Besides being nice, this will hopefully let us manage Doxygen's XML output so as to make extracting series-specific pieces via Breathe in the leaflabs-docs repo possible.

* Make USB its own submodule.Marti Bolivar2012-04-111-4/+6
| | | | | | | | | | | | | | | Add libmaple/usb/rules.mk, which compiles the USB FS device firmware submodule. Move the logic for compiling the USB stack from libmaple/rules.mk into libmaple/usb/rules.mk. Move libmaple/usb/usb_cdacm.h to libmaple/include/libmaple/. Its API is sufficiently general that we'll be able to port it over to USB OTG (either FS or HS) eventually, and that lets us include it from Wirish using the new style for libmaple headers. Fix the includes for public libmaple headers within libmaple/usb. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* usb: Rename descriptors.h -> usb_descriptors.h.Marti Bolivar2011-10-211-1/+1
| | | | | | Modify its include guard, and the files that include it, appropriately. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* USB: API cleanups.Marti Bolivar2011-10-211-1/+1
| | | | | | | | | | Modify usb.h functions (changing their names in some cases) to also take a usblib_dev* argument, to fit in better with the rest of libmaple. Store an rcc_clk_id in struct usblib_dev for the same reason. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* USB: API cleanups.Marti Bolivar2011-10-211-1/+10
| | | | | | | | | | | | | | Remove usbSuspend(), usbResumeInit(), usbResume(), the USB low-priority IRQ, and usbWaitReset() from usb.h. Also remove RESUME_STATE since it was only there for usbResume(). These functions don't need to be seen by anybody except for usb.c and usb_cdcacm.c, so move them there (altering their names to fit with libmaple style guidelines) and mark them static. Clean up includes in usb.c while we're there. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm.c: CleanupsMarti Bolivar2011-10-181-200/+202
| | | | | | | | | Move the callbacks to the bottom of the file, and mark them static. Replace empty callbacks with NOP_Process in the callback tables. Remove prototype for nonexistent prep_and_reset(). Other miscellaneous fixups. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb: Clean up some globals with new struct usblib_dev.Marti Bolivar2011-10-181-29/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add struct usblib_dev (and USBLIB, a pointer to the singleton) to usb.h. USBLIB contains the global state which is used by functionality imported from usb_lib/. Consolidating global state into USBLIB will make it easier to remove later. Initial fields in struct usblib_dev are endpoint interrupt callbacks, a mask for what to handle in the low-priority USB interrupt, and device state. These replace pEpInt_IN, pEpInt_OUT; wInterrupt_Mask; and bDeviceState, respectively from usb_lib/, so remove their declarations from usb_lib_globals.h accordingly. Also remove unused SaveState declaration from usblib_globals.h. Move bDeviceState into 'state' field in usblib_dev. Device state type changes from DEVICE_STATE to usb_dev_state, volatile gets dropped, and enumerators get a 'USB_' prefix, but it's otherwise the same. usb_lib/ expects pInformation to point to Device_Info, pUser_Standard_Requests -> User_Standard_Requests, and pProperty -> Device_Property. Alter usb_init_usblib() to reflect these assumptions. Reorganize usb_lib_globals.h to make these assumptions more apparent to the reader. Modify usb_init_usblib() to take endpoint callbacks as arguments; update its caller in usb_cdcacm.c. usb_lib/ defines pInformation, pProperty, and pUser_Standard_Requests itself (in usb_init.c), but we have our own definitions (in usb.c). Remove the duplicates from usb.c. Also remove EPindex and Device_Info definitions from usb.c. Unused, and anyways already defined in usb_lib/usb_init.c.

* Remove usb_config.h.Marti Bolivar2011-10-181-5/+9

* usb: Disentangle CDC ACM functionality.Marti Bolivar2011-10-181-0/+742
Add new usb_cdcacm.h, which provides the virtual serial port API. This file (and new usb_cdcacm.c) consolidate the VCOM support, which was previously distributed through descriptors.[hc], usb.[hc], usb_callbacks.[hc], and usb_config.h. Add usb_init_usblib() to usb.h, as a way of initializing the USB peripheral in terms of the data structures required by usb_lib. This is used by the new usb_cdcacm_enable(). Create new usb_lib_globals.h, with declarations for the usb_lib global state which is most used throughout the rest of the libmaple USB stack. Remove descriptors.c and usb_callbacks.[hc]; they are no longer necessary. Update the USB README accordingly. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
