* 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>

* Port test-usart-dma.cpp to use tube API.Marti Bolivar2012-06-151-13/+61
| | | | | | | | This is straightforward. Do it in a verbose style with lots of comments, so we can use this patch as an example for how to port existing DMA code. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* test-usart-dma.cpp: tweaks.Marti Bolivar2012-06-131-16/+17
| | | | | | | Touch up comments, change some function names, and don't set something to zero which already is. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* examples/test-usart-dma.cpp: Cleanups and comments.Marti Bolivar2012-06-131-49/+78
| | | | | | | | Someone pointed to this example on the DMA page in the wiki, so it's probably worth making it more clear what's going on. Remove unused code, add comments, and move things around for better exposition. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Globally switch style for GPIO config routines.Marti Bolivar2012-06-031-1/+1
| | | | | | | | | | | | | | | | | | | | Stupidly, spi_gpio_cfg() didn't take a spi_dev* argument on F1, because it doesn't matter there. On F2, where we need to set an alternate function when configuring GPIOs for SPI, we need to know the dev. We can't add break backwards compatibility, so we need a new function. However, we've since added a bunch of foo_gpio_cfg() routines, and we don't want confusing asymmetry in the names. So a global style change is needed. (Fortunately, the new functions weren't part of a release, so it's no problem to change their names). Change all foo_gpio_cfg() routines to foo_config_gpios() (or foo_config_gpio(), if there's only one GPIO to configure). For backwards compatibility, make spi_gpio_cfg() on F1 an __always_inline call to spi_config_gpios(). Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

* Fix a bunch of Doxygen file-level comments.Marti Bolivar2012-05-081-1/+1
| | | | | | | | | | | | | 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.

* Move public headers to include directories; related cleanups.Marti Bolivar2012-04-1122-41/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* test-fsmc.cpp: Switch to SerialUSBMarti Bolivar2011-09-261-33/+28
| | | | | | | This messes with timing a little, but makes it faster to test. The timing was never perfect anyway, due to incrementing count. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

| | | | Measure pins one at a time.
* test-session.cpp: Multiple ADC noise measurements by default.Marti Bolivar2011-08-311-15/+20
| | | | | Each call to measure_adc_noise() now does N_ADC_NOISE_MEASUREMENTS (currently 40) samples, instead of just 1.
* test-session.cpp: Better analog noise readings.Marti Bolivar2011-08-311-8/+9
| | | | | | | | | | | | | | | | | | | | | | | | Update measure_adc_noise() to actually use the Welford online algorithm, instead of accumulating data in an array on the stack. This allows us to increase the number of samples (to 1000). Revised algorithm tested on host PC and compared (in Python) against numpy with a list of 100 values in [0, 1) drawn using random.random(). Results (Python): >>> r = [random.random() for i in xrange(100)] >>> numpy.mean(r) 0.50073064742634854 >>> numpy.var(r) 0.083726090293309297 Results (C++, x86 host PC): n: 100 mean: 0.500731 variance: 0.084572 So this algorithm for variance has some inaccuracies, but it appears to be good to a couple of significant figures.

* Keep it 80-column clean.Marti Bolivar2011-06-071-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Go through overlong source code lines and convert as many of them as appropriate to be 80-column clean. This mostly affects license headers. Overlong lines are determined by running following from the libmaple base directory: $ ack-grep --nocolor --nogroup --cpp --cc --ignore-dir=usb -- '.{80}' Note that this excludes libmaple's usb subdirectory, which is still full of ST code that doesn't follow the libmaple source code guidelines. Contents of ~/.ackrc (these won't matter, but are included for completeness): --ignore-dir=docs --ignore-dir=build --type-set ld=.ld --type-set rst=.rst --type-set txt=.txt --type-set mk=.mk

* Changing integration date of function in examples/test-timer.cpp.Marti Bolivar2011-05-051-1/+1
| | | | | | | It would be nice to have something like a timer_set_period() in libmaple proper that takes the period and the clock rate as parameters, much the same as usart_set_baud_rate() does. No time for that now, though, so punt to 0.1.0.

* SPI refactor.Marti Bolivar2011-04-281-0/+197
| | | | | | | | | | | | | | | | | Still a polling driver, but the libmaple proper interface exposes enough that users enable the various interrupts and define their own IRQ handlers if they feel like it. Wirish HardwareSPI interface was largely redone; it's more like the Arduino implementation now, although there are some differences when I didn't like their API. The old methods are still there, but are deprecated and slated for deletion in 0.1.0. New board-specific values: BOARD_NR_SPI, BOARD_SPIx_NSS_PIN, BOARD_SPIx_MOSI_PIN, BOARD_SPIx_MISO_PIN, and BOARD_SPIx_SCK_PIN, for x from 1 to BOARD_NR_SPI. Documentation was updated appropriately.
