Otherwise the RMT will repeat pulses when using loop(True). This repeating
is due to a bug in the IDF which will be fixed in an upcoming release, but
for now the accepted workaround is to swap these calls, which should still
work in the fixed version of the IDF.
Fixes issue #6167.
With only `sp_func_proto_paren = remove` set there are some cases where
uncrustify misses removing a space between the function name and the
opening '('. This sets all of the related options to `force` as well.
There are a maximum of 8 USB endpoints and each has 2 buffer slots
(in/out). This commit add support for up to 8 endpoints and adds FIFO
configuration for USB profiles with 2xVCP on MCUs that have device-only USB
peripherals.
Tested on NUCLEO_WB55 in 2xVCP, 2xVCP+MSC and 2xVCP+MSC+HID mode.

The ESP32 RMT peripheral has hardware support for a carrier frequency, and
this commit exposes it to Python with the keyword arguments carrier_freq
and carrier_duty_percent in the constructor. Example usage:
r = esp32.RMT(0, pin=Pin(2), clock_div=80, carrier_freq=38000, carrier_duty_percent=50)
Zephyr renamed CONFIG_FLOAT to CONFIG_FPU to better reflect its semantics
of enabling the hardware floating point unit (FPU) rather than enabling
toolchain-level floating point support (i.e., software floating point for
FPU-less socs).
Zephyr deprecated and then removed its stack_analyze function because it
was unsafe. Use the new zephyr thread analyzer instead and rename the
MicroPython function to zephyr.thread_analyze() to be more consistent with
the implementation.
Tested on mimxrt1050_evk.
The output now looks like this:
>>> zephyr.thread_analyze()
Thread analyze:
80004ff4 : unused 400 usage 112 / 512 (21 %)
rx_workq : unused 1320 usage 180 / 1500 (12 %)
tx_workq : unused 992 usage 208 / 1200 (17 %)
net_mgmt : unused 656 usage 112 / 768 (14 %)
sysworkq : unused 564 usage 460 / 1024 (44 %)

Sending more than 64 bytes to the USB CDC endpoint in HS mode will lead to
a hard crash. This commit fixes the issue, although there may be a better
fix from upstream TinyUSB in the future.
With this commit the code should work correctly regardless of the size of
StackType_t (it's actually 1 byte in size for the esp32's custom FreeRTOS).
Fixes issue #6072.
This commit implements an LED class with rudimentary parts of a pin C API
to support it. The LED class does not yet support setting an intensity.
This LED class is put in the machine module for the time being, until a
better place is found.
One LED is supported on TEENSY40 and MIMXRT1010_EVK boards.
Changes are:
- string0 is no longer built when building for host as the target, because
it'll be provided by the system libc and may in some cases clash with the
system one (eg on OSX).
- mp_int_t/mp_uint_t are defined in terms of intptr_t/uintptr_t to support
both 32-bit and 64-bit builds.
- Configuration values which are the default in py/mpconfig.h are removed
from mpconfigport.h to make the configuration a bit more minimal, eg as
a better starting point for new ports.
Microwatt may have firmware that places data in r3, which was used to
detect microwatt vs powernv. This breaks the existing probing of the UART
type in this powerpc port.
Instead build only the appropriate UART into the firmware, selected by
passing the option UART=potato or UART=lpc_serial to the Makefile.
A future enhancement would be to parse the device tree and configure
MicroPython based on the settings.
The code previously called rtc_get_reset_reason which is a "raw" reset
cause. The ESP-IDF massages that for the proper reset cause available from
esp_reset_reason.
Fixes issue #5134.
Add configuration which otherwise has to be set via the UI so the file is
more self-contained, and remove configuration which is not needed because
it's the same as the default. The major change here is that for a while
now Appveyor has been using Visual Studio 2015 by default while we still
want to support 2013.
Older implementations deal with infinity/negative zero incorrectly. This
commit adds generic fixes that can be enabled by any port that needs them,
along with new tests cases.
The linker script was included in the "$^" inputs, causing the build to
fail:
LINK build/firmware.elf
powerpc64le-linux-gnu-ld: error: linker script file 'powerpc.lds' appears multiple times
As a fix the linker script is left as a dependency of the elf, but only the
object files are linked.
The PWM driver uses a double buffer for the PWM timing array, one in
current use and the other one to update when changing duty parameters.
The issue was that once the duty parameters were changed the updated buffer
was applied immediately without synchronising to the start of the PWM
period. By moving the buffer toggling/swapping to the interrupt when the
cycle is done there are no more glitches.
Commit 6cea369b89 updated the TinyUSB
submodule to a version based on nrfx v2.0.0. This commit updates the nrf
port to work with the latest TinyUSB and nrfx v2.0.0.
