Reset related functions ----------------------- .. function:: reset() Resets the WiPy in a manner similar to pushing the external RESET button. .. function:: reset_cause() Get the reset cause. See :ref:`constants ` for the possible return values. Interrupt related functions --------------------------- .. function:: disable_irq() Disable interrupt requests. Returns the previous IRQ state: ``False``/``True`` for disabled/enabled IRQs respectively. This return value can be passed to enable_irq to restore the IRQ to its original state. .. function:: enable_irq(state=True) Enable interrupt requests. If ``state`` is ``True`` (the default value) then IRQs are enabled. If ``state`` is ``False`` then IRQs are disabled. The most common use of this function is to pass it the value returned by ``disable_irq`` to exit a critical section. Power related functions ----------------------- .. function:: freq() Returns a tuple of clock frequencies: ``(sysclk,)`` These correspond to: - sysclk: frequency of the CPU .. function:: idle() Gates the clock to the CPU, useful to reduce power consumption at any time during short or long periods. Peripherals continue working and execution resumes as soon as any interrupt is triggered (including the systick which has a period of 1ms). Current consumption is reduced to ~12mA (in WLAN STA mode) .. function:: sleep() Stops the CPU and disables all peripherals except for WLAN. Execution is resumed from the point where the sleep was requested. Wake sources are ``Pin``, ``RTC`` and ``WLAN``. Current consumption is reduced to 950uA (in WLAN STA mode). .. function:: deepsleep() Stops the CPU and all peripherals including WLAN. Execution is resumed from main, just as with a reset. The reset cause can be checked to know that we are coming from from ``machine.DEEPSLEEP``. Wake sources are ``Pin`` and ``RTC``. Current consumption is reduced to ~5uA. .. function:: wake_reason() Get the wake reason. See :ref:`constants ` for the possible return values. Miscellaneous functions ----------------------- .. function:: main(filename) Set the filename of the main script to run after boot.py is finished. If this function is not called then the default file main.py will be executed. It only makes sense to call this function from within boot.py. .. function:: rng() Return a 24-bit software generated random number. .. function:: unique_id() Returns a string of 6 bytes (48 bits), which is the unique ID of the MCU. This also corresponds to the ``MAC address`` of the WiPy. .. _machine_constants: Constants --------- .. data:: machine.IDLE .. data:: machine.SLEEP .. data:: machine.DEEPSLEEP irq wake values .. data:: machine.POWER_ON .. data:: machine.HARD_RESET .. data:: machine.WDT_RESET .. data:: machine.DEEPSLEEP_RESET .. data:: machine.SOFT_RESET reset causes .. data:: machine.WLAN_WAKE .. data:: machine.PIN_WAKE .. data:: machine.RTC_WAKE wake reasons Classes ------- .. toctree:: :maxdepth: 1 machine.ADC.rst machine.I2C.rst machine.Pin.rst machine.RTC.rst machine.SD.rst machine.SPI.rst machine.Timer.rst machine.UART.rst machine.WDT.rst @ 1.1 log @Initial revision @ text @@ 1.1.1.1 log @Import micropython version 1.5.2 into othersrc. Micropython is a python3 implementation that has been optimised for micro-controllers and small embedded systems. It also has a "unix" port. It has an MIT license. This is version 1.5.2 of micropython. MicroPython implements the entire Python 3.4 syntax (including exceptions, "with", "yield from", etc.). The following core datatypes are provided: str (including basic Unicode support), bytes, bytearray, tuple, list, dict, set, frozenset, array.array, collections.namedtuple, classes and instances. Builtin modules include sys, time, and struct. Note that only subset of Python 3.4 functionality implemented for the data types and modules. This is the standard micropython source (version v1.5.2), which has been adapted to use reachover infrastructure. At the present time, libffi (from pkgsrc) is used. Alternative locations for libffi can be set using the PKGSRC_PREFIX definition to make. In the whole scheme of things, micropython is quite small: % size bin/micropython text data bss dec hex filename 393495 1624 2208 397327 6100f bin/micropython % and runs much as expected: % bin/micropython MicroPython v1.5.2 on 2016-01-13; linux version Use Ctrl-D to exit, Ctrl-E for paste mode >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> % python2.7 Python 2.7.10 (default, Oct 17 2015, 17:55:29) [GCC 4.8.5] on netbsd7 Type "help", "copyright", "credits" or "license" for more information. >>> print("hello world") hello world >>> list(5 * x + y for x in range(10) for y in [4, 2, 1]) [4, 2, 1, 9, 7, 6, 14, 12, 11, 19, 17, 16, 24, 22, 21, 29, 27, 26, 34, 32, 31, 39, 37, 36, 44, 42, 41, 49, 47, 46] >>> ^D % This (reachover) version runs all the tests which the gmake version does. % make t cd bin && make t cd /home/agc/local/micropython/bin/../dist/unix/../tests && env MICROPY_MICROPYTHON=/home/agc/local/micropython/bin/micropython ./run-tests pass basics/0prelim.py pass basics/andor.py pass basics/array1.py pass basics/array_add.py pass basics/array_construct.py pass basics/array_construct2.py ... pass unix/ffi_callback.py pass unix/ffi_float.py pass unix/ffi_float2.py 474 tests performed (15812 individual testcases) 474 tests passed 5 tests skipped: cmd_showbc cmd_verbose machine1 machine_mem extra_coverage % The sources are available from github: https://github.com/micropython/micropython micropython release at: https://github.com/micropython/micropython/releases Sources for 1.5.2 taken from: https://github.com/micropython/micropython/archive/v1.5.2.tar.gz Alistair Crooks agc@@netbsd.org Wed Jan 13 17:15:30 PST 2016 @ text @@
