| | | | | | | | | | | Added a generic pure abstract class to provide the interface for all Wire implementations. Modified the old Wire library using software interface to use the new Base Wire abstract class. Added a new library which allows the use of the Wire class to use the I2C hardware. Changed default pin numbers for Software Wire library to match pin numbers used for I2C/TWI shields created for the Arduino. Signed-off-by: Trystan Jones <crenn6977@gmail.com>

* Add CREDITS file.Marti Bolivar2012-06-282-0/+84
| | | | | | | | | | | | | | | | | 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>

|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Merge the long-lived (too long; future changes like these will need to proceed more incrementally) development branch of libmaple, containing experimental STM32F2 and STM32F1 value line support, into master. 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>

| * Bring back and fix up util.c functionality.Marti Bolivar2012-06-264-77/+171
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Rip out the existing nonportable pieces, and shove them under wirish/stm32f1, using weak symbols so users who only want libmaple proper don't end up with build errors. Add stubbed-out (and only partially functional) definitions for F2 targets under wirish/stm32f2. The behavior on F103 targets is the same as it was before (though the assertion framework has always been broken and badly needs replacement, that awaits another commit). We additionally now skip re-enabling USB on F1 targets without USB, to make things work on value line MCUs. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

| * I2C: Move CCR/TRISE config helper back to libmaple/i2c.c.Marti Bolivar2012-06-222-37/+41
| | | | | | | | | | | | | | | | | | | | | | | | We can implement it in terms of _i2c_bus_clk() instead of hard-coding STM32_PCLK1. This might be overkill, since I2C peripherals are slow and thus likely to be on APB1 for all STM32 devices (that is the case for F2/F4, for instance), but if we're going to have _i2c_bus_clk(), we might as well respect it.

| * i2c_dev: deprecate .gpio_port.Marti Bolivar2012-06-224-23/+77
| | | | | | | | | | | | | | | | | | | | | | | | | | This won't work on F2, which at times has SDA and SCL on different ports (e.g. I2C3 SDA on PC9, SCL on PA8). Add .sda_port and .scl_port replacements, which are used when the now-deprecated .gpio_port is null. Use them correctly everywhere, with some new i2c_private.h helper functionality. Sigh. The F1 I2C code tries too hard to guess what you wanted; it's not porting well at all. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

| | | | | | | | | | | | | | | | This is ad-hoc and nonportable. If you really want I2C mapped elsewhere, then mess with the I2C device fields and call afio_remap() yourself. (This is also cleaner for F2). Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>

| * i2c_set_input_clk(): fix an F1-ism.Marti Bolivar2012-06-222-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | i2c_set_input_clk()'s documentation says that the maximum peripheral clock frequency is 36 MHz, but that's a hard-coded magic number. The actual limit is the device's APB frequency or 46 MHz, whichever is lower (F2 and F4 share the 46 MHz limit). Fix the documentation to reflect that fact, and add an internal series-provided function to get the maximum clock frequency for a device. To help users porting to F2, have i2c_set_input_clk() assert-check that the provided frequency is less than that maximum value and the hard 46 MHz limit.
