This commit introduces a few changes aimed at reducing the amount of space taken by the inline assembler once compiled: * The register string table uses 2 bytes for each qstr rather than the usual 4 * The opcode table uses 2 bytes for each qstr rather than the usual 4 * Opcode masks are not embedded in each opcode entry but looked up via an additional smaller table, reducing the number of bytes taken by an opcode's masks from 12 to 2 (with a fixed overhead of 24 bytes for the the masks themselves stored elsewhere) * Some error messages had a trailing period, now removed * Error messages have been parameterised when possible, and the overall text length is smaller.

This commit changes the Xtensa inline assembly parser to use a slightly simpler (and probably a tiny bit more efficient) way to look up register names when decoding instruction parameters. Signed-off-by: Alessandro Gatti <a.gatti@frob.it>
The mantissa parsing code uses a floating point variable to accumulate digits. Using an `mp_float_uint_t` variable instead and casting to `mp_float_t` at the very end reduces code size. In some cases, it also improves the rounding behaviour as extra digits are taken into account by the int-to-float conversion code. An extra test case handles the special case where mantissa overflow occurs while processing deferred trailing zeros. Signed-off-by: Yoctopuce dev <dev@yoctopuce.com>

This commit gives the option to not pass an I2C Bus ID when creating a machine I2C object. If the ID is not provided, the default bus ID (which is `PICO_DEFAULT_I2C`) is used. This allows users to simply declare an I2C object with `machine.I2C()` without passing any arguments, thus creating an object with the default I2C ID, SCL, and SDA. Signed-off-by: Malcolm McKellips <malcolm.mckellips@sparkfun.com>
Similar to the previous commit, this allows constructing an I2C instance without specifying an ID. The default ID is I2C_NUM_0. Signed-off-by: Malcolm McKellips <malcolm.mckellips@sparkfun.com>
Changes: - To add user to Linux dialout group, usermod is the universal Linux way. adduser is Debian-based way. - When installing IDF, we don't have to install all toolchains for all chips. - List currently supported chip models. - Other minor typo and gramma corrections.

Particularly for out of tree builds, one may need to provide alternative or extra linker fragment files, or specify an absolute path to the default `linker.lf` file. In the default case, do nothing, provide a plain `linker.lf`, as before. Signed-off-by: Karl Palsson <karl.palsson@marel.com>
The actual output pin value is taken from the OUT register, not from the pad. Tested with: - ESP32 low and high Pin numbers - ESP32C3 low Pin numbers - ESP32C6 low Pin numbers - ESP32S2 low and high Pin numbers - ESP32S3 low and high Pin numbers Signed-off-by: robert-hh <robert@hammelrath.com>

A new module called renesas is added, like in other ports. The accessible
block device allows to use Python methods for creating and modifying the
file system. The Flash block device for the file system can be accessed
with:
from renesas import Flash
bdev = Flash(start=0)

This change allows tuples to be passed as the prefix/suffix argument to the `str.startswith()` and `str.endswith()` methods. The methods will return `True` if the string starts/ends with any of the prefixes/suffixes in the tuple. Also adds full support for the `start` and `end` arguments to both methods for compatibility with CPython. Tests have been updated for the new behaviour.

If a board configures a default I2C instance and/or SCL/SDA pins, then these no longer need to be given in the constructor. This allows the user to easily construct the default I2C instance via `machine.I2C()` and that will work on the default pins as designated on the board silkscreen. Signed-off-by: robert-hh <robert@hammelrath.com>
If a board configures a default SPI instance and/or SCK/MOSI/MISO pins, then the user can create a default SPI object using `machine.SPI()`. Also, if MISO is not going to be used, then MISO can be set to `None` with `miso=None`. Signed-off-by: robert-hh <robert@hammelrath.com>
If a board configures a default UART instance and/or TX/RX pins then the user can create a default UART object using `machine.UART()`. Signed-off-by: robert-hh <robert@hammelrath.com>
These were missing and are needed to support UART/I2C/SPI default pins. Signed-off-by: robert-hh <robert@hammelrath.com>
In combination with the defautl Pins the default device can now be instantiated e.g. as: uart = UART(). Similar for I2C and SPI. Signed-off-by: robert-hh <robert@hammelrath.com>
Changes are: - Add the RX/TX pins to the table. In most cases these are the D0/D1 pins. - Document the ability for the instantiation of the default devices without submitting ID or pins. - Improve the example script creating the pin list to show multiple name assigments to the same pin. - Fix errors in the pinout document.

For a given MicroPython firmware/executable it can be sometimes important to know how it was built, which variant/board configuration it came from. This commit adds a new field `sys.implementation._build` that can help identify the configuration that MicroPython was built with. For now it's either: * <VARIANT> for unix, webassembly and windows ports * <BOARD>-<VARIANT> for microcontroller ports (the variant is optional) In the future additional elements may be added to this string, separated by a hyphen.

Or use C++ `static_assert` when that's available.
For the same reasons that C++ has trouble with "nonconstexpr" static
assertions, `_Static_assert` rejects such expression as well. So, fall
back to the old sizeof-array based implementation in that case.
When `_Static_assert` can be used, the diagnostic quality is improved:
../py/objint.c: In function ‘mp_obj_int_make_new’:
../py/misc.h:67:32: error: static assertion failed: "37 == 42"
../py/objint.c:45:5: note: in expansion of macro ‘MP_STATIC_ASSERT’
As compared to a diagnostic about
../py/misc.h:71:50: error: size of unnamed array is negative
Testing on godbolt indicated that this actually works back to gcc 4.5, but
it's easier to use GNUC >= 5 as the test; hypothetical users of 4.5, 4.6,
or 4.7 will just get slightly worse diagnostics.
