* DMA checkpoint; dma_attach_interrupt() is broken.Marti Bolivar2011-04-113-148/+695
| | | | | | Simple USART receiver to SRAM buffer demo partially working. Interrupting when buffer is full fails mysteriously. GDB thinks we ended up in an STM32 reserved exception.

* USART bugfix.Marti Bolivar2011-04-111-1/+1
| | | | | USART refactor commit f6f9a1122706ed336c52c984d76219dee0594487 only worked for USART1.
* USART fixups.Marti Bolivar2011-04-081-2/+2
| | | | | | | * usart_enable(): Doxygen comment bugfix. * usart_disable(): previously, usart_disable() would nuke the entire CR1 register just to clear the UE bit.

* SysTick refactor.Marti Bolivar2011-04-053-56/+81
| | | | | | | | For the changelog: * util.h is free of __read(), __write(), etc. macros. * systick_resume() was renamed systick_enable().

|
* ring_buffer tweaks.Marti Bolivar2011-04-051-2/+6
| | | | | | | Adding basic ring_buffer test (cherry-pick from master). Changing rb_safe_insert()'s type to match that of rb_push_insert(). (Makes it easier to pass around insertion functions.)

* Final stm32_pin_info design candidate; ADC3 support on Native.Marti Bolivar2011-03-253-98/+265
| | | | | | | | | | | | | | | | | | | | Added an adc_dev to struct stm32_pin_info. This was necessary to add support for the channels on the Native which are only connected to ADC3, but it does add a bunch of NULLs to the PIN_MAPs. I don't think any other peripherals need representation on a per-pin basis. Each peripheral library will be responsible for keeping track of related GPIO ports and bits, and we can throw #defines in to boards/*.h for other things (e.g. BOARD_SPI1_MISO_PIN). Fleshed out the ADC refactor and brought it more in keeping with the new design as it evolves. A couple of other tweaks. Notably: waitForButtonPress() now takes a default argument meaning "wait forever". Removed Maple-specific documentation from core functions in io.h; this information will need to go into the individual board docs files.
* Adding /wirish/boards/ for easier porting; shrank PIN_MAPs.Marti Bolivar2011-03-242-38/+56
| | | | | | | | | | | | | | | | | /wirish/boards/ contains xxx.h and xxx.cpp (for xxx=maple, maple_native, maple_mini, maple_RET6). The headers contain the board-specific #defines that used to live in boards.h (except BOARD_INIT, which was removed). The CPP files contain the PIN_MAP definitions that used to live in boards.cpp, and a proper boardInit() function to replace the old BOARD_INIT macro. This will make it easier to add new boards in the future. struct PinMapping was renamed struct stm32_pin_info, and was moved into a new wirish_types.h. Its external interrupt field was moved into struct gpio_dev, which saves memory by storing an afio_exti_port per port, rather than one per pin. Also rearranged the stm32_pin_info fields to improve packing. Maple's PIN_MAP is now down to below 500 bytes.
* timer_set_dma_burst_length() and TIMER8 comment bugfixesMarti Bolivar2011-03-241-2/+2

* Initial timer refactor.Marti Bolivar2011-03-2410-1013/+1522
| | | | | | | | | | | | | | | Basic PWM works. Had some problems in testing that might be due to USART bugs. HardwareTimer has been removed from the build for now; I will re-implement it in terms of the new libmaple API, but consider it deprecated. Let's come up with something better. Servo is implemented in terms of HardwareTimer, so it also has been temporarily removed from the build. pwmWrite() likely got a little bit less inefficient due to indirection, but the PIN_MAPs shrank by a pointer per PinMapping.

* RCC refactor.Marti Bolivar2011-03-213-178/+563
| | | | | | Older refactor commit e4807a5010f59ab863ad2c96dc14caf65bf1ae60 used bit-banding in rcc_clk_init() to set RCC_CR_HSEON, which doesn't work for some reason. Not going to try to figure out why.

* | Cleaned out libmaple.h; this had wide-ranging implications.Marti Bolivar2011-02-2714-216/+210
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
