Paul Sokolovsky 6d103b6548 py: Move call_function_*_protected() functions to py/ for reuse.
They almost certainly needed by any C code which calls Python callbacks.

Damien George 32d7cf6e44 esp8266: Implement basic deep-sleep capabilities.
Use the machine.deepsleep() function to enter the sleep mode.  Use the
RTC to configure the alarm to wake the device.

Basic use is the following:

    import machine

    # configure RTC's ALARM0 to wake device from deep sleep
    rtc = machine.RTC()
    rtc.irq(trigger=rtc.ALARM0, wake=machine.DEEPSLEEP)

    # do other things
    # ...

    # set ALARM0's alarm to wake after 10 seconds
    rtc.alarm(rtc.ALARM0, 10000)

    # enter deep-sleep state (system is reset upon waking)
    machine.deepsleep()

To detect if the system woke from a deep sleep use:

    if machine.reset_cause() == machine.DEEPSLEEP_RESET:
        print('woke from deep sleep')

Damien George a525493e40 esp8266: Switch from using custom I2C driver to generic extmod one. 2016-04-12 14:06:54 +01:00
Damien George 1a0a323ca8 esp8266: Add initial implementation of machine.UART.
Currently UART(0) and UART(1) are exposed and only uart.write works.

Damien George 632d8efa05 esp8266: Add PWM support.
PWM implementation uses a timer and interrupts (FRC1), taken from
Espressif's/NodeMCU's implementation and adapted for our use.

8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15.

Usage:

    import machine
    pwm0 = machine.PWM(machine.Pin(0))
    pwm0.freq(1000)
    pwm0.duty(500)

Frequency is shared (ie the same) for all channels.  Frequency is
between 1 and 1000.  Duty is between 0 and 1023.

Damien George 82b95f625e esp8266: Implement software SPI class.
Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any
pins.  Only supports MSB output at the moment.
