Specifically, at least Ubuntu's i586-mingw32msvc-gcc doesn't supply
__LITTLE_ENDIAN__ and friends. And as it's safe enough to assume that
Windows is only little-endian, then it's defined unconditionally,
instead of duplicating detection logic in py/mpconfig.h (or adding
windows-specific defines to it).
If micropython.native decorator doesn't compile, then we skill all
native/viper tests.
This patch also re-enables the ujson_loads test on NT.
Addresses issue #861, and partially addresses issue #856.
Found these by compiling stmhal with mp_uint_t of type uint32_t instead
of unsigned int. This actually makes a difference to the code, but just
a curiosity.
This has benefits all round: code factoring for parse/compile/execute,
proper context save/restore for exec, allow to sepcify globals/locals
for eval, and reduced ROM usage by >100 bytes on stmhal and unix.
Also, the call to mp_parse_compile_execute is tail call optimised for
the import code, so it doesn't increase stack memory usage.
Timers now have the following new features:
- can init freq using floating point; eg tim.init(freq=0.1)
- tim.source_freq() added to get freq of timer clock source
- tim.freq() added to get/set freq
- print(tim) now prints freq
Eg pyb.freq(120000000) sets the CPU to 120MHz. The frequency can be set
at any point in the code, and can be changed as many times as you like.
Note that any active timers will need to be reconfigured after a freq
change.
Valid range is 24MHz to 168MHz (but not all freqs are supported). The
code maintains a 48MHz clock for the USB at all times and it's possible
to change the frequency at a USB REPL and keep the REPL alive (well,
most of the time it stays, sometimes it resets the USB for some reason).
Note that USB does not work with pyb.freq of 24MHz.
Remove reference to pyb.gc; add reference to pyb.millis.
There are lots of functions not listed when you run help(), but it would
be too much to list them all, so we list only some basic, useful ones.
Addresses issue #846.
