The uos.dupterm() signature and behaviour is updated to reflect the latest
enhancements in the docs. It has minor backwards incompatibility in that
it no longer accepts zero arguments.
The dupterm_rx helper function is moved from esp8266 to extmod and
generalised to support multiple dupterm slots.
A port can specify multiple slots by defining the MICROPY_PY_OS_DUPTERM
config macro to an integer, being the number of slots it wants to have;
0 means to disable the dupterm feature altogether.
The unix and esp8266 ports are updated to work with the new interface and
are otherwise unchanged with respect to functionality.
* atmel-samd: Add support for internal filesystems.
This allows us to re-enable `os`. `random` is also enabled because
it solely depends on `os`.
Fixes#266. Its also a pre-requisite for #260.
* atmel-samd: Update SAMD51 linker script comments and MICROPY_MAX_STACK_USAGE enabling.
So that a pointer to it can be passed as a pointer to math_generic_1. This
patch also makes the function work for single and double precision floating
point.
This patch changes how most of the plain math functions are implemented:
there are now two generic math wrapper functions that take a pointer to a
math function (like sin, cos) and perform the necessary conversion to and
from MicroPython types. This helps to reduce code size. The generic
functions can also check for math domain errors in a generic way, by
testing if the result is NaN or infinity combined with finite inputs.
The result is that, with this patch, all math functions now have full
domain error checking (even gamma and lgamma) and code size has decreased
for most ports. Code size changes in bytes for those with the math module
are:
unix x64: -432
unix nanbox: -792
stm32: -88
esp8266: +12
Tests are also added to check domain errors are handled correctly.
This saves a lot of RAM. Fixes#287.
Also fixed compilation of frozen_mpy.c to use supplied make rule rather than
builtin rule (supplied rule suppresses printing out the gcc command line).
While this console API improves handling on real hardware boards
(e.g. clipboard paste is much more reliable, as well as programmatic
communication), it vice-versa poses problems under QEMU, apparently
because it doesn't emulate UART interrupt handling faithfully. That
leads to inability to run the testsuite on QEMU at all. To work that
around, we have to suuport both old and new console routines, and use
the old ones under QEMU.
We want to close communication object even if there were exceptions
somewhere in the code. This is important for --device exec:/execpty:
which may otherwise leave processing running in the background.
Ideally, these should be configurable from Python (using network module),
but as that doesn't exist, we better off using Zephyr's native bootstrap
configuration facility.
The poweroff() and poweron() methods are used to do soft power control of
the display, and this patch makes these methods work the same for both I2C
and SPI interfaces.
Backport of micro:bit random module.
Plugged into the port as a general random module for all nrf51/nrf52 targets. Works both with and without Bluetooth LE stack enabled.
Behavioral change: seed() method has been removed, as the use of RNG peripheral generates true random sequences and not pseudo-random sequences.
The driver also takes care of calling the Bluetooth LE stack for random values if the stack is enabled. The reason for this is that the Bluetooth LE stack take ownership of the NRF_RNG when enabled. Tolerate to enable/disable on the fly, and will choose to use direct access to the peripheral if Bluetooth LE stack is disabled or not compiled in at all.
Driver has been included in the top Makefile, and will not be compiled in unless nrf51_hal_conf.h/nrf52_hal_conf.h defines HAL_RNG_MODULE_ENABLED (1).
