2013-01-16Remove assembly forcing stack.Karl Palsson
Fixes #51 There should be no reason for manually trying to load the stack. Cortex devices can be programmed with only C, and any code that needed this would indicate broken vectors.

2013-01-10platform-independent makefile: fix old "stm32" referencechrysn
the "make clean" target showed a constant "stm32/f1" debug message instead of the current relative directory. this is fixed by showing the relevant portion of the current directory instead, relevant being determined by evaluating the current makefile's relative position and stripping that part off.

2013-01-09lm4f: Add API for controlling the system run clock sourcesAlexandru Gagniuc
Add an abstraction layer to handle the clock control for the run time clock on LM4F (RCC). Sleep and deep-sleep clock configuration is not handled. Complete documentation for the clock control API is included in doxygen-style comments, and is included in [doc]. Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com> Conflicts: lib/lm4f/Makefile
2013-01-09lm4f: Add API for enabling/disabling peripherals clock sourceAlexandru Gagniuc
The enum definitions are specified in the form 31:5 register offset from SYSCTL_BASE for the clock register 4:0 bit offset for the given peripheral The names have the form [clock_type]_[periph_type]_[periph_number] Where clock_type is RCC for run clock SCC for sleep clock DCC for deep-sleep clock Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>

F2/4 has now I2C3 included
2013-01-08IWDG moved to common areaKen Sarkies
2013-01-08Move usart files to common areaKen Sarkies
Again added to L1 which is similar to F1
2013-01-08Move DAC to common areaKen Sarkies
(Note there are now dummy source files dac.c (and others) that are not compiled but are needed for documentation).
2013-01-08STM32: Moved SPI code into the common area.Ken Sarkies
Updated the documentation so that it appears in all families Also added it to the L1 area, but is untested. An addition to the memorymap allows commonality and a #ifdef added to the spi_common_all code to exclude the case of SPI3 for L1 and F0 as SPI3 doesn't exist in those. An rcc dispatch header was added to remove same code from the spi header.
2013-01-08Move STM32F1 DMA files to respective common directoriesKen Sarkies
This sets the stage for adding DMA to STM32F3xx (when added) and STM32L1xx as the controller appears to be identical in these.
2013-01-08STM32 DMA: replaced F4 header to match that for F2, and move header and ↵Ken Sarkies
source files to common. In the header: - Fix DMA_SxCR_CT: change shift from 18 to 19 For use with the convenience functions: - Added DMA_SxCR_CHSEL generic values - Added DMA_STREAM - generic values - Added dma_if_offset - rather than separating out LISR and HISR - Added masks - Added dma_disable_double_buffer_mode()

2012-12-31lm4f: Compile in the interrupt vector tableAlexandru Gagniuc
Add an "#ifdef(LM4F)" clause to include/libopencm3/dispatch/nvic.h and lib/dispatch/vector_nvic.c. This compiles in the vector table and allows interrupts to be used. Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>
2012-12-31lm4f: Compile with FPU supportAlexandru Gagniuc
Specify the -mfloat-abi=hard and -mfpu=fpv4-sp-d16 flags so that FPU is enabled by default. While this compiles with FPU support, in order to use the floating point types, the FPU must be explicitly enabled at runtime. Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>

2012-12-31lm4f: Add lm4f support files copied from lm3sAlexandru Gagniuc
Create lm4f code infrastructure from the lm3s infrastructure. As far as the interrupt table is concerned, don't create an irq.yaml. Just include the LM3S nvic.h. The LM3S vector table seems to be compatible with the LM4F Signed-off-by: Alexandru Gagniuc <mr.nuke.me@gmail.com>

2012-11-14stm32/f4/adc: DMA can always be used with ADC2Ben Gamari
I can't find any evidence in the manual to support this comment's claim.
2012-11-14[l1] Add common timer code support.Karl Palsson
This has only been tested functionally with basic timers, and basic operations. Advanced timer support has been #ifdefed to compile, but this probably needs more testing.
2012-11-14[l1] Add rcc clock setup helper routinesKarl Palsson
Despite the L1 being a low power device, my initial focus is on making it basically compatible with existing devices. To that end, provide clock setup helper routines that configure it for maximum performance, allowing some similar clock speeds to F1 devices to help with testing. This requires adding the power chipset routines to set the voltage range. Clock setup style is similar to the F4 code, which seems nicer than the overflow of different routines used on the F1 code. NOTE: Both the F4 existing pwr code, and this code don't actually include the f1 core power code, even though it should be compatible
2012-11-14[l1] Add Flash Memory Controller Register defns for L1.Karl Palsson
Also, some of the most basic essential helper functions.
