Josef Gajdusek 9e00ac89d5 esp8266: Add esp.socket class, with ESP-style socket functionality.
* UDP currently not supported
 * As there is no way (that I know of) the espconn_regist_connectcb()
   callback can recognize on which socket has the connection arrived,
   only one listening function at a time is supported

Micro Python port to ESP8266

This is a port of Micro Python to the Espressif ESP8266 wifi module.

Currently implemented features include:

  • REPL (Python prompt) over UART0.
  • 24k heap RAM available for Python code.
  • Garbage collector, exceptions.
  • Unicode support.
  • Builtin modules: gc, array, collections, io, struct, sys.
  • C long-long type used as bignum implementation (gives 64 signed ints).

Note that floating-point numbers are not supported.

On the TODO list:

  • Wifi support.
  • GPIO 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.

Then, to build Micro Python for the ESP8266, just run:

$ 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
