* 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 Bolivar2012-08-042-64/+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>

* test session: Add SerialUSB benchmark to 'U' command.Marti Bolivar2012-08-031-4/+20
| | | | | | | | I'm currently measuring over 500 KB/sec with screen as my serial monitor. If I don't display the output at all, I get over 600 KB/sec. Nice! 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 Bolivar2012-08-012-11/+11
| | | | | | This keeps things in line with the specification, helping readability. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Move CDC ACM config. descriptor into usb_cdcacm.c.Marti Bolivar2012-07-312-15/+15

* Move bootloader details out of libmaple.h.Marti Bolivar2012-07-312-8/+12
| | | | | | Finally! Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* HardwareSerial: make read() block until data arrive.Marti Bolivar2012-07-311-0/+3
| | | | | | | This makes the HardwareSerial behavior match that of SerialUSB, and should help avoid confusion. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Move bootloader reset signal detection to Wirish.Marti Bolivar2012-07-313-127/+140
| | | | | | | | 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 Bolivar2012-07-312-27/+39
| | | | | | | | | | | 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 Bolivar2012-07-312-0/+44
| | | | | | | | 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 Bolivar2012-07-312-84/+93
| | | | | | | | | 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>
* Hack: Provide a hook so Mini doesn't disable JTAG/SWD.Marti Bolivar2012-07-311-1/+3
| | | | | | | The nonexistence of a configuration system is starting to become kind of a pain. Oh well; let's keep piling hacks on until things break. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* Add pin alias enums to other boards.Marti Bolivar2012-07-245-0/+41
| | | | | | | | Repeat Anton's VLDiscovery trick on the rest of the boards. Leave out st_stm3220g_eval since that's just a teaser to get people to play with F2. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* stm32loader.py: Cosmetics.Marti Bolivar2012-07-241-23/+22
| | | | | | | Move the actual QUIET setting to above mdebug(); that was confusing. Rename _wait_for_ask to _wait_for_ack. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* stm32loader.py: Updates for F2 and F4.Marti Bolivar2012-07-241-7/+51
| | | | | | | | | | | | | Support the extended erase memory command, which replaced the erase memory command in the bootloader protocol as of version 3.0. This takes a long time, so tweak _wait_for_ask to take an extra timeout for special cases like this. Use this under if __name__ == '__main__' to support F2 and F4. Additionally, produce a human-readable report of the target chip from its chip ID. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

| | | | | | | | | | | | | | | | | It's about time. This initial file is based on the output of $ git log | grep Author | sort | uniq It leaves out credit for patches that were later reverted or moved out of libmaple. It also doesn't credit the many patches and other bugfixes from users who've e.g. written in the forum describing their changes, but didn't submit actual patches. Names aren't always available in cases like those, but if the contributors come forward, we'd be happy to add them. Add note in HACKING about adding yourself to CREDITS.

* reset.py: Use the real print function (requires Python 2.6+).Marti Bolivar2012-06-281-14/+16
| | | | | | | | | | | | | | | | | | | | | | Use "from __future__ import print_function" so the recent py3k compatibility patches to reset.py preserve the old output in Python 2. This increases our minimum Python version to 2.6, but avoids ugly output Python 2, where print statements with a tuple argument print the tuple with parentheses etc. Python 2.6 came out almost four years ago, and it's widely available: - even on older Linux distros (e.g. Ubuntu 10.04 and Debian Squeeze have 2.6 default at time of writing), - on OS X since 10.6, - and Windows users will probably be installing from python.org anyway, so they've likely got a reasonably recent vintage. Dropping 2.5 support thus doesn't seem likely to cause problems. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

This required many changes to the structure of the library. The most important structural reorganizations occurred in: - 954f9e5: moves public headers to include directories - 3efa313: uses "series" instead of "family" - c0d60e3: adds board files to the build system, to make it easier to add new boards - 096d86c: adds build logic for targeting different STM32 series (e.g. STM32F1, STM32F2) This last commit in particular (096d86c) is the basis for the repartitioning of libmaple into portable sections, which work on all supported MCUs, and nonportable sections, which are segregated into separate directories and contain all series-specific code. Moving existing STM32F1-only code into libmaple/stm32f1 and wirish/stm32f1, along with adding equivalents under .../stm32f2 directories, was the principal project of this branch. Important API changes occur in several places. Existing code is still expected to work on STM32F1 targets, but there have been many deprecations. A detailed changelog explaining the situation needs to be prepared. F2 and F1 value line support is not complete; the merge is proceeding prematurely in this respect. We've been getting more libmaple patches from the community lately, and I'm worried that the merge conflicts with the old tree structure will become painful to manage. Conflicts: Makefile Resolved Makefile conflicts manually; this required propagating -Xlinker usage into support/make/target-config.mk. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
