This commit adds the option to use HSE or MSI system clock, and LSE or LSI
RTC clock, on L4 MCUs.
Note that prior to this commit the default clocks on an L4 part were MSI
and LSE. The defaults are now MSI and LSI.
In mpconfigboard.h select the clock source via:
#define MICROPY_HW_RTC_USE_LSE (0) or (1)
#define MICROPY_HW_CLK_USE_HSE (0) or (1)
and the PLLSAI1 N,P,Q,R settings:
#define MICROPY_HW_CLK_PLLSAIN (12)
#define MICROPY_HW_CLK_PLLSAIP (RCC_PLLP_DIV7)
#define MICROPY_HW_CLK_PLLSAIQ (RCC_PLLQ_DIV2)
#define MICROPY_HW_CLK_PLLSAIR (RCC_PLLR_DIV2)
The the nrfx driver is aware of chip specific registers, while
the raw HAL abstraction is not. This driver enables use of NVMC
in non-secure domain for nrf9160.
This patch moves the check for MICROPY_PY_MACHINE_TEMP to come
before the inclusion of nrf_temp.h. The nrf_temp.h depends on
the NRF_TEMP_Type which might not be defined for all nRF devices.
For use with F0 MCUs that don't have HSI48. Select the clock source
explicitly in mpconfigboard.h.
On the NUCLEO_F091RC board use HSE bypass when HSE is chosen because the
NUCLEO clock source is STLINK not a crystal.
Before this patch the UART baudrate on F0 MCUs was wrong because the
stm32lib SystemCoreClockUpdate sets SystemCoreClock to 8MHz instead of
48MHz if HSI48 is routed directly to SYSCLK.
The workaround is to use HSI48 -> PREDIV (/2) -> PLL (*2) -> SYSCLK.
Fixes issue #5049.
Enabled by default, but disabled when REPL is connected to the VCP (this is
the existing behaviour). Can be configured at run-time with, eg:
pyb.USB_VCP().init(flow=pyb.USB_VCP.RTS | pyb.USB_VCP.CTS)
The new fdcan.c file provides the low-level C interface to the FDCAN
peripheral, and pyb_can.c is updated to support both traditional CAN and
FDCAN, depending on the MCU being compiled for.
Add the project file to the mpy-cross directory, which is also where the
executable ends up, and change the Appveyor settings to build mpy-cross
with both msvc and mingw-w64 and verify this all works by running tests
with --via-mpy.
If this is not set it might default to calls to open() to use text mode
which is usually not wanted, and even wrong and leading to incorrect
results when loading binary .mpy files.
This also means that text files written and read will not have line-ending
translation from \n to \r\n and vice-versa anymore. This shouldn't be much
of a problem though since most tools dealing with text files adapt
automatically to any of the 2 formats.
Reserve sources.props for listing just the MicroPython core and extmod
files, similar to how py.mk lists port-independent source files. This
allows reusing the source list, for instance for building mpy-cross. The
sources for building the executable itself are listed in the corresponding
project file, similar to how the other ports specify the source files in
their Makefile.
Append to PyIncDirs, used to define include directories specific to
MicroPython, instead of just overwriting it so project files importing this
file can define additional directories. And allow defining the target
directory for the executable instead of hardcoding it to the windows
directory. Main reason for this change is that it will allow building
mpy-cross with msvc.
We want the .vcxproj to be just a container with the minimum content for
making it work as a project file for Visual Studio and MSBuild, whereas the
actual build options and actions get placed in separate reusable files.
This was roughly the case already except some compiler options were
overlooked; fix this here: we'll need those common options when adding a
project file for building mpy-cross.
These were probably added to detect more qstrs but as long as the
micropython executable itself doesn't use the same build options the qstrs
would be unused anyway. Furthermore these definitions are for internal use
and get enabled when corresponding MICROPY_EMIT_XXX are defined, in which
case the compiler would warn about symbol redefinitions since they'd be
defined both here and in the source.
This commit adds support for a second supported hash (currently set to the
4.0-beta1 tag). When this hash is detected, the relevant changes are
applied.
This allows to start using v4 features (e.g. BLE with Nimble), and also
start doing testing, while still supporting the original, stable, v3.3 IDF.
Note: this feature is experimental, not well tested, and network.LAN and
network.PPP are currently unsupported.
This option affects py/vm.c and py/gc.c and using -Os gets them compiling a
bit smaller, and small firmware is the aim of these two ports. Also,
having these files compiled with -Os on these ports, and -O3 as the default
on other ports, gives a better understanding of code-size changes when
making changes to these files.
According to the schematic, the SDRAM part on this board is a
MT48LC4M32B2B5-6A, with "Row addressing 4K A[11:0]" (per datasheet). This
commit updates mpconfigboard.h from 13 to 12 to match.
