* [WIP] GPIO refactor: seems ok, ready for reviewMarti Bolivar2011-03-111-22/+13

* Cleaned out libmaple.h; this had wide-ranging implications.Marti Bolivar2011-02-271-11/+22
| | | | | | | | | | | | | | | | | | | Many of the #defines in libmaple.h were board-specific, not MCU-specific. Most of these were only used by code under libmaple/usb/. These were moved into usb_config.h, and are clearly marked as being terrible hacks. I'm going to treat the USB stack as a black box that we'll deal with later. Further, instead of having a variety of #defines like "How many USARTS do I have?", we decide that based on the density of the chip. This is determined by testing for STM32_MEDIUM_DENSITY or STM32_HIGH_DENSITY defines. libmaple currently doesn't support low-density chips, so that suffices. The Makefile will set these automatically based on the MCU. Other offending #defines are ERROR_LED_PORT and ERROR_LED_PIN; these were made optional, but they're set in the Makefile as a hack to keep things working.
* libmaple: Refactor ADC routinesPerry Hung2011-02-271-1/+2
| | | | | | ADC routines rewritten, support for ADC2, 3, added. Signed-off-by: Marti Bolivar <mbolivar@leaflabs.com>
* Merge branch 'nzmichaelh-master' into master.Marti Bolivar2011-02-161-4/+4
|\ | | | | | | | | | | | | | | | | This provides DMA, IWDG, PWR, and BKP support, and fixes several bugs. Conflicts: libmaple/adc.h libmaple/libmaple.h libmaple/ring_buffer.h
| * nzmichaelh's pull request mods compile and upload.Marti Bolivar2010-12-281-4/+4
| | | | | | | | renamed SysTick_Handler back to SysTickHandler since all of our linker magic/lanchon-stm32 depends on that name. added backup register support in order to test independent watchdog support; it seems to work. next major test target is DMA support.

* Enable USB auto-reset in a hard fault.Perry Hung2010-09-171-0/+1
| | | | | | | | Redirect thread-mode execution to a fail routine which throbs the LED to indicate a hard fault. Because the fail routine runs in thread mode with interrupts on, USB auto-reset should now work. Test by executing some bogus instruction (e.g. *(volatile int*)0xf34fdaa = 0;) and check that the auto-reset continues to work.

* Cleaned up wirish/time, some interrupt handling refactoring:Perry Hung2010-08-041-2/+0
| | | | | | | | | Fixed millis(), it was just wrong, before. Added micros(), not extensively tested. New implementation of delayMicroseconds(). Should be more consistent now. Added a handful of nvic routines to enable/disable interrupts. Cleaned up systick
* Turn off MAPLE_DEBUG by default.Perry Hung2010-08-041-1/+1
| | | | | Save space on debug strings, performance. Perhaps we should consider some form of user-facing assert.
* New usart implementation:Perry Hung2010-08-041-0/+2
| | | | | | Fixed a bug where the maximum baud rate was incorrectly set to 225000 General cleanup Use new rcc and nvic APIs
* Licensing: Relicensed libmaple under the MIT License.Perry Hung2010-03-311-12/+17
| | | | | | Relicensed the bulk of libmaple under the more permissive MIT License, from GPLv3. Files that were largely or entirely derived from the Arduino, STM, or Lanchon retain their original licenses.
* Removed inttypes.hPerry Hung2010-03-311-13/+12
| | | | | Removed inttypes.h from libmaple. Will have another pass through to use the standard libmaple types, but will come in another commit.
