L4 and F3 actually have the same bits to write in the same order, but F3 hides
the name of the deep power down bit. Keep the like that for now, but there's a
standard API for enabling and disabling the regulator.
The adc v2 periph has the same register map, but comes in two flavours, one
supporting injected channels, more watchdogs, per channel sampling times and
so on, and one "simple" version.
Pull up the f3 and f0 portions into the appropriate files, after comparing with
L0 and L4 reference manuals, even if those are not fully landed yet.
The f0, f30x and l0 have a very similar "v2" adc peripheral.
Start extracting out some of the common code, and fix the glaring bug in
adc_power_down that was affecting them both.
This is not intended to be a fully comprehensive extraction, just the first
easy steps.
The adc peripheral on F30x is the same as F0, L0 and L4. In the reference
manuals, the following names are used.
F3: CFGR (no CFGR2)
F0 and L0: CFGR1 and CFGR2
L4: CFGR and CFGR2
Moving to a single consistent name, that's more likely to be inline with future
part numbers makes it much easier to extract common driver code for the
peripheral.
While all bit defines are moved to the CFGR1 style, core register definitions:
ADC_CFGR(adc) and ADCx_CFGR are kept to match the original register name in the
reference manual.
Fixes Github issue #548
There are as many SMPRx registers are needed for channels supported, and on all
other families, the field definitions are just ADC_SMPR_SMP_XXX. For
consistency, and to avoid any confusion or duplication, use the same style here
too. Drop silly unused per channel definitions that have no purpose.
At least temp sensor, vrefint and vbat/vlcd should have consistent names and
consistent doxygen.
Dropped channel definitions that are the same as the raw number.
All the macro arguments that are user supplied, or potentially, wrap properly
in () as good practice.
Probably missed one or two, and a lot of them are possibly unnecessary, but
it's straightforward to just do it always.
Fixes github issue #321
The f3 adc has separate bits for end of conversion and end of sequence.
Support those fully, with the regular enable/disable irq methods, and
the flag checking methods.
Discovered in github bug: #493
This code was copied from the f4, and blindly modified to make it seem
to work. The f3 has separate flags for EOC and EOS, it doesn't use a
second bit to configure what the EOC bit does.
Consequently, update the documentation to correctly indicate that the
EOC bits are only set per conversion.
Discovered in github bug: #493
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 pulls out all the common header definitions for the F1, L1, F4 and F37x
parts. It's verified against the datasheet for F2 as well, but we don't have
any good F2 test boards or any support for that yet. (The F2 header would be
_exactly_ the same as the F4 header, so it's a target for a future round of
unification, not this one)
Tested with f1, f4 and l1 examples from the examples repository.
According to RM0090, page 301, paragraph 11.13.12 Note. (For F4, for F1 and F3 is it in the corresponding manuals)
The JSQR are filled always ending at SQR4 ie for those lists we must set this list:
(A) -> JSQ4 = A,
(A,B) -> JSQ3 = A, JSQ4 = B,
(A,B,C) -> JSQ2 = A, JSQ3 = B, JSQ4 = C,
(A,B,C,D) -> JSQ1 = A, JSQ2 = B, JSQ3 = C, JSQ4 = D,
The readed values are in correct order, starting from JDR1:
(A) -> JDR1 = A,
(A,B) -> JDR1 = A, JDR2 = B,
(A,B,C) -> JDR1 = A, JDR2 = B, JDR3 = C,
(A,B,C,D) -> JDR1 = A, JDR2 = B, JDR3 = C, JDR4 = D,
