these register definitions are common to all cortex mcus. some of the
registers might not be implemented everywhere (especially the floating
point registers), but defining them does no harm.
this modification does not result in any changes in the example
binaries.
Conflicts:
lib/lm3s/vector.c -- split out to lm3s/irq.h
lib/stm32/f4/vector.c -- put the floating point initialization code into a function like in lpc43xx
Add object files to Makefile to include new modules into lib.
Correct typo in pwr.c
Add two new functions to timer.c to preset the counter (for use
with deadman style timeouts) and to identify an interrupt
source.
Also noticed lib/makefile.include didn't clean lib/stm32, which
isn't a target. Added a fix.
remove rcc_set_adc_clk - use rcc version
Added functions:
- adc_power_on
- adc_start_conversion_direct
- adc_set_dual_mode
- adc_eoc
- adc_eoc_injected
- adc_read_regular
- adc_read_injected
- adc_set_injected_offset
Tested dual mode scanned regular, but no tests of injected yet.
Changes: "discontinuous" was misspelled.
- adc_set_discontinuous_mode_regular - added "length" parameter
- adc_disable_discontinuous_mode_regular - name change
- adc_enable_discontinuous_mode_injected - name change
- adc_enable_automatic_injected_group_conversion - disable triggers
- adc_enable_jeoc_interrupt - name change to match common usage in lib
- adc_disable_jeoc_interrupt - ditto
- adc_enable_external_trigger_regular - remove incorrect test on parameter
- adc_enable_external_trigger_injected - ditto
- adc_set_sample_time - name change to match function's purpose
- adc_set_conversion_time_on_all_channels - ditto
- adc_set_injected_sequence - changed order of register loading (ref Barlow's issue)
- adc_enable_analog_watchdog_on_all_channels - flipped AWDSGL
- adc_enable_analog_watchdog_on_selected_channel - ditto
added aliases for expected commonly used functions to avoid sudden user code breakage
In adc.h, corrected errors in SQR names
added "deprecated" compiler warnings to adc_on and to aliases defined in adc.c
the cortex generic interrupts get moved to lib/cm3/vector.c, the
platorms' individual irq names, initialization and handler prototypes go
to platoform specific irq.h files.
as the vector.c file heavily depends on platoform specific headers, it
can't be built once-and-for-all in lib/cm3/, so there are inclusion
stubs in the various architecture dirs; this might be better solved with
Makefile / include path handling.
one particular file is lib/lpc43xx/vector.c; that platform's
initialization code contains an additional section to copy everything
from flash to ram (which probably performs better there). that code
still resides in the inclusion stub, and gets mashed in using defines.
would need a cleaner implementation together with the Makefile solution.
this commit contains some files of the upcoming efm32 branch, from which
it was cherry-picked.
the .bin files produced from before and after this commit only differ in
lpc43xx, where the startup sequence was subtly modified.
Adds libopencm3/cm3/assert.h header that provides assertion check macros
similar to those provided by the standard C library.
Thanks to Nicolas Schodet for help.
That way, data source address does not depend on any other unrelated change in
linker script.
This also fixes cases when .data input section is aligned on 8 bytes. The new
version does not provide any address for the output section so that it is
aligned to the strictest input section. The _data_loadaddr symbol will
always take this alignment into account.
In adc.h additional defines needed to assist documentation - lines 172-191
added, and 384,436-451 are duplicates of earlier defines to complete
parameter sets (compiler has no trouble with these).
Minor doc corrections to other files.
No code changes (apart from additional defines).
file having its own group module rather than using @file.
No code changes except for the following:
gpio: Added function to map the eventout signal plus two Remap functions
dma: Prevent changing base addresses while channel enabled (see datasheet)
pwr: Added pwr.c (new file)
timer: Removed the last function that I introduced recently; there is already
an equivalent function present. Changed some parameter names for consistency.
- The library files are now being built into the lib subdirectory of the
source.
- The linker files for each library are being copied into the lib source
subdirectory.
Motivation: The relative locations of files in the source directory after make
are now the same as after make install now. This makes it easier to
reuse examples with their makefiles outside of the libopencm3
sourcecode directory.
1. Remove the extra mask (TIM_DIER(timer_peripheral) & flag)
in timer_get_flag. Not all flags in SR relate to IRQs and the flags that
do might be useful even if interrupts not enabled.
2. In a number of functions (e.g. timer_set_output_idle_state) that only
apply to advanced timers, add test for TIM1 and TIM8, as done in some others.
3. Added timer_force_event to manipulate the EG register
TBD DMA burst - can't get my head around why this would be useful.
Someone must have thought so!
Working unique id support, but not 100% convinced that this is the "least surprise"
path. ST's docs provide the bits from low to high, in 2xu16 and 2xu32.
But to get it back as a "u96" the highest bits should be first?
IDR represents the level on pin input while ODR is the value requested by the
programmer. This makes a difference for example when using the output as open
drain.
