Paul Sokolovsky 98af891610 esp8266: Implement input part of dupterm handling.
The idea is following: underlying interrupt-driven or push-style data source
signals that more data is available for dupterm processing via call to
mp_hal_signal_dupterm_input(). This triggers a task which pumps data between
actual dupterm object (which may perform additional processing on data from
low-level data source) and input ring buffer.

MicroPython port to ESP8266

This is a highly experimental port of MicroPython for the WiFi modules based on Espressif ESP8266 chip.

WARNING: The port is highly experimental and any APIs are subject to change.

Currently implemented features include:

  • REPL (Python prompt) over UART0.
  • Garbage collector, exceptions.
  • Unicode support.
  • Builtin modules: gc, array, collections, io, struct, sys, esp, network, many more.
  • Arbitrary-precision long integers and 30-bit precision floats.
  • Basic WiFi support.
  • Sockets using modlwip.
  • GPIO and bit-banging I2C, SPI support.
  • 1-Wire and WS2812 (aka Neopixel) protocols support.

On the TODO list:

  • Full wifi support.
  • Internal filesystem using the flash.
  • ...

Build instructions

The tool chain required for the build is the OpenSource ESP SDK, which can be found at https://github.com/pfalcon/esp-open-sdk. Clone this repository and run make in its directory to build and install the SDK locally. Make sure to add toolchain bin directory to your PATH.

Add the external dependencies to the MicroPython repository checkout:

$ git submodule update --init

See the README in the repository root for more information about external dependencies.

Then, to build MicroPython for the ESP8266, just run:

$ cd esp8266
$ make

This should produce binary images in the build/ subdirectory. To flash them to your ESP8266, use:

$ make deploy

This will use the esptool.py script to download the images. You must have your ESP module in the bootloader, and connected to a serial port on your PC. The default serial port is /dev/ttyACM0. To specify another, use, eg:

$ make PORT=/dev/ttyUSB0 deploy

The images that are built are:

  • firmware.elf-0x00000.bin: to be flashed at 0x00000
  • firmware.elf-0x10000.bin: to be flashed at 0x10000

There is also a combined image, made up of the above 2 binary files with the appropriate padding:

  • firmware-combined.bin: to be flashed at 0x00000
