The f107 ethernet peripheral is the same as in f4, and was pulled out
into lib/ethernet/mac_stm32fxx7.c in 52758bb8fdf065d46ef1ea21cc383e2dc74ee19b
This drops the duplicate code.
Fixes Github issue #694
The TSVREFE bit is defined to only be present on ADC1, so drop the
pointless adc argument. This has the added benefit of making the
API consistent with all other STM32 adc parts.
Use same names as adv-v2 peripheral uses. F1 is the only v1 peripheral
adc that has calibration modes at all.
Old:
adc_calibration(ADC1); // blocking call
New (blocking):
adc_calibrate(ADC1);
New (asynch):
adc_calibrate_async(ADC1);
// do stuff
adc_is_calibrating(ADC1); // false when calibration finished
Old routines are preserved but marked deprecated for now.
Start providing async routines for all blocking routines, to make it
easier to use libopencm3 in some RTOS environments. This is not in
anyway intended to be complete, this just covers a single blocking
routine, rcc_wait_for_osc_ready. Documentation added to the top level,
and provided for all stm32 families.
Connectivity line devices have more remaps available, and the existing code was
artificially and needlessly preventing those remaps from being set, even if
defined.
While implementing this, the existing code to handle SWJ remap was found to be
inconsistent with the reference manual and has been fixed.
Fixes github issue #369
DESIG_FLASH_SIZE is provided for all stm32 parts in desig.h, correctly defined
as 16bits. Remove the incorrect duplicate definition within the f1 flash
handling code.
Fixes github issues #621
As done by esden for the F4, remove typedefs and add prefixes to clock enums
This extends this to all stm32 families.
Let's not hide the fact that these variables are structs/enums.
We are filling up the namespace badly enough, we should be prefixing as
much as we can with the module names at least. As users we already run
often enough in namespace colisions we don't have to make it worse.
* CLOCK_3V3_xxx enums renamed to RCC_CLOCK_3V3_xxx
* clock enums (PLL, HSI, HSE ...) prefixed with RCC_
* scale enum of pwr module prefixed with PWR_
Was only in the (obviously out of date) documented example and as a
declaration. No implementations. Dropping immediately, but documentation
still needs further work.
Renamed every instance of variable CFLAGS in target specific Makefiles
to TGT_CFLAGS to free up CFLAGS for user defined compiler flags.
Added information in README.md about existence and usage of CFLAGS
environment variable in build process.
The breaking changes here changes in header location, and changes in driver
name passed down to the usb stack.
Changes affect: stm32f102/f103, stm32l1, and some f3 parts
* instead of the confusingly generic "usb" use the name "st_usbfs" for the USB
Full speed peripheral ST provides in a variety of their stm32 products.
Include directives should change as:
#include <libopencm3/stm32/usb.h> => <libopencm3/stm32/st_usbfs.h>
* instead of the confusingly specific "f103" name for the driver, use
"st_usbfs_v1" [BREAKING_CHANGE]
Instead of:
usbd_init(&stm32f103_usb_driver, .....) ==>
usbd_init(&st_usbfs_v1_usb_driver, .....) ==>
The purpose of these changes is to reduce some confusion around naming, but
primarily to prepare for the "v2" peripheral available on stm32f0/l0 and some
f3 devices.
Work by Frantisek Burian, Kuldeep Singh Dhaka, Robin Kreis, fenugrec and zyp
on irc, and all those forgotten.
We haven't yet moved everything over to any autogenerated linker scripts, so
include more common templates instead of proliferating mountains of them in
every example.
(probably because the Ref Manual erroneously required it).
This has a naughty side-effect in that unrelated user data in the BD would be wiped.
Replaced this call by clearing the RTC registers to their default values.
Tested with ET-STAMP-STM32 to verify RTC starts from power-on and reset with expected behaviour.
-ggdb3 make slightly bigger .elf files, but allows gdb to understand
macros, which libopenocm3 uses somewhat extensively. Make this the
default, and pull it up to the common base makefile, so it can be easily
substituted.
This adds MCO source selection to some targets, and removes and standardizes
the mask/shift usage for all targets. For devices that support MCO2, this
supports only MCO1. No attempt has been made to extract MCO prescaler, which
is not available on all F1 and F3.
Rename rcc_ppre1_frequency and rcc_ppre2_frequency to rcc_apb1_frequency and rcc_apb2_frequency
Also add rcc_ahb_frequency (although it is not set correctly in all cases) which will be fixed by
the rcc commits later. Also fixup the only use in the library of these variables, the USART code.
And fix the typos that resulted
Make l1 generic too
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.
On linux, the output of CP rule was try to write to / which is - of course, forbidden for write.
This solution adds to each part of lib correct pointer to the root of lib where the libs should be written.
Bug found by Kuldeep Singh Dhaka.
Extension of code for STM32F1 to allow for dual bank series XL.
Small changes to documentation for F2, F4 and L1 to add a parameter reference.
Tested with STM32F103RBT6
(note: tests show that the PG bit must be cleared after programming, otherwise
a subsequent erase attempt fails. This has been added to flash_program_half_word
for F0 and F1 only. A fix for the other families is not included in this PR.)
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
https://github.com/karlp/libopencm3/tree/rme_l1_master
So that the navigation pane works correctly in browsers.
Some additional doc fixes put in where found (but many more still to go).
Added some dummy .c and .h files to bring the associated docs into line.
makefile changed to allow 'make html' as well as 'make doc' (the latter only does html anyway).
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,
The common code wasn't being included in L1 builds, even though the headers now
included the correct definitions.
This combines the two f0 and f3 spi files, which previously differed only in
the number of spi peripherals defined.
Files were renamed to the full "l1f124" style, not because I like it, but
because it's the convention we have, so it's best to apply it rigourously.
Tested on L1 and F100 boards, compile tested only for others, but the examples
repository all compiles too. (Though the lack of SPI examples for all
platforms was how this broke in the first place)
We currently default to "-mfloat-abi=hard -mfpu=fpv4-sp-d16" for M4F cores, and
and variations of "-mfloat-abi=soft" for the others. Keep the M4F default, and
move others to no FP flags for consistency, but allow overriding these flags
via the FP_FLAGS environment variable.

Because most changes are internal to a function in exti.c I am leaving
the macro checks in there, otherwise we would end up with a bunch of
code duplication if we used the dispatch system used otherwise
throughout the stm32 part of the library. I bet it could be split up
into more granular functions resulting in more generic code that we
could run through the dispatch system. But I am leaving that as an
excersize for later.
We don't support f0 yet so let's not fool anyone. We may rename those
files back again if when we cross check that it is actually true this
file supports f0.
In places where we were defining memory mapped peripheral buffers we
were using directly a cast to "volatile int_type *". For consistency we
should use dereferenced accessor like: &MMIO32(address)
