This patch makes a repeat counter behave the same as repeating the
typecode, when there are not enough args. For example:
struct.pack('2I', 1) now behave the same as struct.pack('II', 1).
Similar to the existing testcase, but test that returning both value of
native type and instance of another user class from __new__ lead to
__init__ not being called, for better coverage.
NotImplemented means "try other fallbacks (like calling __rop__
instead of __op__) and if nothing works, raise TypeError". As
MicroPython doesn't implement any fallbacks, signal to raise
TypeError right away.
This upgrades the HAL to the versions:
- F4 V1.16.0
- F7 V1.7.0
- L4 V1.8.1
The main changes were in the SD card driver. The vendor changed the SD
read/write functions to accept block number intead of byte address, so
there is no longer any need for a custom patch for this in stm32lib.
The CardType values also changed, so pyb.SDCard().info() will return
different values for the 3rd element of the tuple, but this function was
never documented.
The unary-op/binary-op enums are already defined, and there are no
arithmetic tricks used with these types, so it makes sense to use the
correct enum type for arguments that take these values. It also reduces
code size quite a bit for nan-boxing builds.
The SPI flash driver now supports using an arbitrary SPI object to
communicate with the flash chip, and in particular can use a hardware SPI
peripheral.
Otherwise, it will silently get incorrect result on other values types,
including CPython tuple form like "foo.png".endswith(("png", "jpg"))
(which MicroPython doesn't support for unbloatedness).
Allows for simpler, smaller and faster code at run time when selecting the
boards frequency, and allows more customisation opportunities for the PLL
values depending on the target MCU.
Changes for F7 are:
- machine.reset_cause() now reports DEEPSLEEP_RESET correctly;
- machine.sleep() is further optimised to reduce power consumption;
- machine.deepsleep() is now implemented and working.
For SEEK_SET, offset should be treated as unsigned, to allow full-width
stream sizes (e.g. 32-bit instead of 31-bit). This is now fully documented
in stream.h. Also, seek symbolic constants are added.
Too big positive, or too big negative offset values could lead to overflow
and address space wraparound and thus access to unrelated areas of memory
(a security issue).
State that this doc describes generic, "core" MicroPython functionality,
any particular port may diverge in both directions, by both omitting
some functionality, and adding more, both cases described outside the
generic documentation.
