Drops all the l1 copies of this code, and automatically gains all the
following apis that weren't even available before:
void adc_set_clk_prescale(uint32_t prescaler);
void adc_set_resolution(uint32_t adc, uint32_t resolution);
void adc_enable_overrun_interrupt(uint32_t adc);
void adc_disable_overrun_interrupt(uint32_t adc);
bool adc_get_overrun_flag(uint32_t adc);
void adc_clear_overrun_flag(uint32_t adc);
bool adc_awd(uint32_t adc);
void adc_eoc_after_each(uint32_t adc);
void adc_eoc_after_group(uint32_t adc);
void adc_set_dma_continue(uint32_t adc);
void adc_set_dma_terminate(uint32_t adc);
Only applied to STM32 doc trees at present.
Instead of declaring a group for "STM32blah" in the doc-blah.h files,
and then trying to put all the common+specific peripheral code into
those groups, (which is what led to the stub doxygen holder empty .c
files) Just use a standard name like "Peripheral APIS" and place
everything into that.
Demonstrated by converting ADC and USART peripherals, which is
definitely not complete, but it shows how to make things less magical,
and less prone to copy/paste errors. Now, you can copy/paste and it
will do the right thing, because everyone uses the same group names.
This is also how to unify the mix of "STM32blah->Periphblah" and _also_
the dangling "periph_file" modules in doxygen, it merges them together
properly, as they're intended to be really.
to remove variations, redundancies, add missing, fix errors. All c files
refer only to the dispatch style headers in /include/stm32. Those headers
#include memorymap.h and cm3/common.h. All references to
these are removed from the family specific headers. Ethernet untouched as
it appears incomplete.
Added dummy spi.c for F0/F3. Fix some doxygen anomalies.
This unifies stm32f1, l1, and f4 convenience functions for adc. The code
should be useable for f2 and f37x as well, but that needs hardware for testing,
and there was no existing implementation. This is the reason for the
"adc_common_v1.c" name, as trying to put all the different families into the
common file name has become too cumbersome.
All of the deprecated routines have been dropped, they've been marked
deprecated for a very long time now, and porting them seemed unnecessary.
This has been tested on f1, l1 and f4 discovery boards, and is based on some
existing l1/f1 unification code from
