Paul Sokolovsky 688cc79294 zephyr/Makefile: Allow to adjust heap size from make command line. 2016-11-04 19:09:39 +03:00
Daniel Thompson 67b6d9d499 zephyr: Initial implementation of machine.Pin.
The integration with Zephyr is fairly clean but as MicroPython Hardware API
requires pin ID to be a single value, but Zephyr operates GPIO in terms of
ports and pins, not just pins, a "hierarchical" ID is required, using tuple
of (port, pin). Port is a string, effectively a device name of a GPIO port,
per Zephyr conventions these are "GPIO_0", "GPIO_1", etc.; pin is integer
number of pin with the port (supposed to be in range 0-31).

Example of pin initialization:

pin = Pin(("GPIO_1", 21), Pin.OUT)

(an LED on FRDM-K64F's Port B, Pin 21).

There is support for in/out pins and pull up/pull down but currently
there is no interrupt support.

Daniel Thompson 479b961d39 zephyr: Implement utime module.
This provides time and sleep together with the usual ticks_us/_ms/_diff
and sleep_us/ms family.

We also provide access to Zephyr's high precision timer as ticks_cpu().

Paul Sokolovsky b440307b4a py/py.mk: Automatically add frozen.c to source list if FROZEN_DIR is defined.
Now frozen modules generation handled fully by py.mk and available for reuse
by any port.

Daniel Thompson b6a544b917 zephyr: Implement the help() function.
The boot issue text mentions a help() function and encourages
the user to run it. It is very disconcerting to find that the
function does not exist...

Daniel Thompson 5a699a7017 zephyr: Use recently added "make outputexports" Zephyr target.
The outputexpors target, which exports Zephyr environment variables, was
recently added to Zephyr. By exploiting this feature we can hugely simplify
the build system, improving robustness at the same time.

Paul Sokolovsky 244b02f744 zephyr/Makefile: Automatically derive target-specific CFLAGS.
By tricking Zephyt arch Makefiles compute them for us (not just for
Zephyr). This make potentially break as Zephyr evolves.

Daniel Thompson cbc0bf6fec zephyr: Support extra make targets
The two variables, GENERIC_TARGETS and CONFIG_TARGETS come, respectively,
from the the lists shown during "make help" and "make kconfig-help".

Daniel Thompson 2ea52cb045 zephyr: Automatically derive ARCH.
Currently to compile for anything that except ARCH=x86 we have to
provide ARCH via the environment or make arguments. We can do better
than that!
