* usb_cdcacm: Expose line coding state.Marti Bolivar2012-08-041-22/+28
| | | | | | | This was already supported, so just move the line coding structure to the header and add some functions for accessing the current values. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm: Set endpoint to NAK before checking byte count.Marti Bolivar2012-08-041-4/+4
| | | | | | Fixes an (admittedly very unlikely) race condition. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Add FIXME for usb_get_ep_tx_count().Marti Bolivar2012-08-041-1/+3
| | | | | | | | | | | We definitely need to mask out the high bits, as RM0008 doesn't specify that they read as zero. Calling this function seems to crash the board, though. I'm not sure why, especially since usb_set_ep_tx_count(), used by usb_cdcacm.c, seems to work. Confusing. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm: various fixups.Marti Bolivar2012-08-041-39/+60
| | | | | | | | | | Mark internal state static. Properly reset the RX/TX state on USB reset. Choose better names for countTx and newBytes. Move the exposed configuration back into the .c; this information is not beneficial to hooks. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm: Improve write speed.Marti Bolivar2012-08-031-4/+3
| | | | | | | | | Actually fill the TX buffer in the packet memory area, so we can send more bytes per transaction. Using the test-session benchmark, we're now clocking in the high 700KB/sec range via PySerial. With screen, rate is now about 550 KB/sec. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* usb_cdcacm: minor fixups.Marti Bolivar2012-08-031-17/+41
| | | | | | | | | | Rename USB_Line_Coding to usb_line_coding, and rename its fields to match the spec to aid searches. Alter the line_coding global to match, fixing an incorrect comment and avoiding magic numbers. Other minor fixups and comment improvements. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm: Rename "notification" -> "management".Marti Bolivar2012-08-011-7/+7

* Move bootloader reset signal detection to Wirish.Marti Bolivar2012-07-311-126/+24
| | | | | | | | Use usb_cdcacm hooks to move the DTR edge and "1EAF" magic packet detection to usb_serial.cpp. We'll later be able to extend this system to support Leonardo-style reset signalling. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm: Add usb_cdcacm_peek().Marti Bolivar2012-07-311-27/+38
| | | | | | | | | | | We need this so the bootloader reset signal detector can look ahead in the byte stream without stealing bytes from the user when "1EAF" isn't received. While we're doing this, take the time to fix a bunch of RX-related code (dead code removal, adding volatile, etc.) Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdacm: Use config instead of magic numbers.Marti Bolivar2012-07-311-2/+2
| | | | | | Sigh. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm: Add hook system.Marti Bolivar2012-07-311-0/+31
| | | | | | | | Provide hooks so users can reach into the CDC ACM callbacks with their own code. We'll use this to move the bootloader reset signals to Wirish. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm: Expose some internal configuration and values.Marti Bolivar2012-07-311-84/+51
| | | | | | | | | Mark the API as unstable so people don't rely on these too hard. (This header is not part of the official libmaple docs). We'll need some of this configuration elsewhere later, and it doesn't make much sense to expose it piecemeal. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm.c: Add another verification TODO.Marti Bolivar2012-07-311-0/+2
| | | | | | | Not sure what the comment above the new TODO is supposed to mean, but it looks like something that should be checked. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb_cdcacm.c: Resolve TODO and improve comments.Marti Bolivar2012-07-311-5/+7
| | | | | | | | | The disc pin code was copy-pasted when the CDC ACM pieces were extracted from the rest of the USB code, and I didn't really understand what was going on when I moved it over. Having checked the spec, the comments can be safely improved. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Doxygen hacks and fixups.Marti Bolivar2012-06-282-2/+2
| | | | | | | | - Shut Doxygen up in various places - Fix some genuine docs bugs - Ignore sources we're not responsible for Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Slightly improve and generify the USB infrastructure.Marti Bolivar2012-06-038-48/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Bolivar2012-05-082-4/+8
| | | | | | | | | | | | | 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.

* libmaple: Add build infrastructure for private headers.Marti Bolivar2012-04-111-1/+1
| | | | | | | | | | | libmaple/rules.mk: Add LIBMAPLE_PRIVATE_INCLUDES, a place for storing headers which should be commonly available throughout libmaple, but not made public. Currently, this is just the libmaple directory. Add LIBMAPLE_PRIVATE_INCLUDES to the target flags in the STM32F1 and USB submodules. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Make USB its own submodule.Marti Bolivar2012-04-117-69/+51
| | | | | | | | | | | | | | | 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>

* Move public headers to include directories; related cleanups.Marti Bolivar2012-04-111-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Move libmaple/*.h to (new) libmaple/include/libmaple/. The new accepted way to include a libmaple header foo.h is with: #include <libmaple/foo.h> This is more polite in terms of the include namespace. It also allows us to e.g. implement the Arduino SPI library at all (which has header SPI.h; providing it was previously impossible on case-insensitive filesystems due to libmaple's spi.h). Similarly for Wirish. The old include style (#include "header.h") is now deprecated. libmaple/*.h: - Change include guard #defines from _FOO_H_ to _LIBMAPLE_FOO_H_. - Add license headers where they're missing - Add conditional extern "C" { ... } blocks where they're missing (they aren't always necessary, but we might was well do it against the future, while we're at it.). - Change includes from #include "foo.h" to #include <libmaple/foo.h>. - Move includes after extern "C". - Remove extra trailing newlines Note that this doesn't include the headers under libmaple/usb/ or libmaple/usb/usb_lib. These will get fixed later. libmaple/*.c: - Change includes from #include "foo.h" to #include <libmaple/foo.h>. Makefile: - Add I$(LIBMAPLE_PATH)/include/libmaple to GLOBAL_FLAGS. This allows for users (including Wirish) to migrate their code, but should go away ASAP, since it slows down compilation. Wirish: - Move wirish/**/*.h to (new) wirish/include/wirish/. This ignores the USB headers, which, as usual, are getting handled after everything else. - Similarly generify wirish/boards/ structure. For each supported board "foo", move wirish/boards/foo.h and wirish/boards/foo.cpp to wirish/boards/foo/include/board/board.h and wirish/boards/foo/board.cpp, respectively. Also remove the #ifdef hacks around the .cpp files. - wirish/rules.mk: put wirish/boards/foo/include in the include path (and add wirish/boards/foo/board.cpp to the list of sources to be compiled). This allows saying: #include <board/board.h> instead of the hack currently in place. We can allow the user to override this setting later to make adding custom board definitions easier. - Disable -Werror in libmaple/rules.mk, as the current USB warnings don't let the olimex_stm32_h103 board compile. We can re-enable -Werror once we've moved the board-specific bits out of libmaple proper. libraries, examples: - Update includes accordingly. - Miscellaneous cosmetic fixups.

* usb.h: Move to libmaple/.Marti Bolivar2011-10-211-82/+0
| | | | | | | | | | | Apart from having an unstable API, usb.h is now a fairly good citizen of libmaple, so move it to live with the rest of the libmaple headers. Its device struct is still "struct usblib_dev". Leave that there; the asymmetry with the rest of the library is a good reminder that the API isn't really on equal footing with the rest of the library. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* USB: API cleanups.Marti Bolivar2011-10-213-23/+22
| | | | | | | | | | 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 Bolivar2011-10-213-39/+31
| | | | | | | | | | | | | | 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.h: Mark API unstable.Marti Bolivar2011-10-211-0/+4
| | | | | | | | The USB API is heavily reliant on the ST stack, and additionally assumes that all USB is the USB FS peripheral. As such, it's going to have to change as we go forward. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Oops; actually remove usb_config.h.Marti Bolivar2011-10-181-45/+0
| | | | | | | | usb_config.h was supposed to be removed in d7afdbe6b41a77938863854a1e719398e6c35094; however, it looks like some merge conflicts stopped that from happening while I was rebasing. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* usb: Clean up some globals with new struct usblib_dev.Marti Bolivar2011-10-184-79/+94
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* usb: Disentangle CDC ACM functionality.Marti Bolivar2011-10-1812-882/+880
| | | | | | | | | | | | | | | | | | | | | 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>
* usb.c: Use usb_reg_map.h; replace most of CTR_LP().Marti Bolivar2011-10-181-90/+244

* usb: Remove usbPowerOff(), move usbPowerOn() to usb_callbacks.c.Marti Bolivar2011-10-183-31/+15
| | | | | | | | | | | Remove usbPowerOn(), usbPowerOff() prototypes from usb.h. These aren't used outside of the USB subsystem, so they don't belong here. Move usbPowerOn() from usb.c to usb_callbacks.c. This is the only place where it's used. Remove the unused usbPowerOff() (from usb.c) altogether. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* usb: Prepare for moving some files to usb_reg_map.h.Marti Bolivar2011-10-184-21/+39
| | | | | | | | | | | | | usb_config.h: Remove usb_regs.h dependency; fix includes; add license. usb_callbacks.h: Change includes to the pieces of usb_lib/ it uses, which doesn't include usb_regs.h. descriptors.h: Remove unused usb_lib.h include. usb.h: Remove unused usb_lib.h include. Some cosmetic commenting. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Add usb_reg_map.h and usb_reg_map.c.Marti Bolivar2011-10-182-0/+512
| | | | | | | | | | | usb_reg_map.h contains the usual register map and register bit definitions that libmaple convention requires. It also contains a variety of structs and convenience functions for accessing and manipulating endpoint registers, BTABLE entries, and PMA buffers.

* Fix memory alignment of USB descriptor structures.RJ Ryan2011-09-182-155/+88
| | | | | | | | | | | | | | | A variety of USB descriptor structures have been manually "unpacked". Instead of using the struct, their members were unpacked into the struct they were nested in. Additionally sizeof()'s were commented in favor of manual calculation of structure sizes. After uncommenting these changes, the USB CDC peripheral stopped correctly configuring with the host. The root problem with the structures is that GCC is padding them. By applying __attribute__((__packed__)), these problems are fixed. I removed all the instances of the workaround I saw within the USB code. Signed-off-by: RJ Ryan <rryan@mit.edu>
