doxygen really wants the @defgroup _and_ the @addtogroup to both have
the full name, matching identically, to avoid all warnings.
Standardize on the "CAPS_PERIPH peripheral API" style.
rcc_osc_bypass_enable and rcc_osc_bypass_disable have been copy/pasted
around for the last time! There's a compile bit to check for L0/L1, but
otherwise this is just code duplication for no gain.
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.
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_
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.
Added --terse and --mailback options to the make stylecheck target. It
also does continue even if it enounters a possible error.
We decided on two exceptions from the linux kernel coding standard:
- Empty wait while loops may end with ; on the same line.
- All blocks after while, if, for have to be in brackets even if they
only contain one statement. Otherwise it is easy to introduce an
error.
Checkpatch needs to be adapted to reflect those changes.
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.
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.
