zephyr: Initial Zephyr RTOS port, MicroPython part.

# This is the main Makefile, which uses MicroPython build system,
# but Zephyr arch-specific toolchain and target-specific flags.
# This Makefile builds MicroPython as a library, and then calls
# recursively Makefile.zephyr to build complete application binary
# using Zephyr build system.

zephyr/Makefile: Allow to adjust heap size from make command line.
2016-11-04 12:09:39 -04:00
# Default heap size is 16KB, which is on conservative side, to let
# it build for smaller boards, but it won't be enough for larger
# applications, and will need to be increased.

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.

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. Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org>

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(). Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org>

modutime.c \
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.
