The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t. |

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.
- 24k heap RAM available for Python code.
- Garbage collector, exceptions.
- Unicode support.
- Builtin modules: gc, array, collections, io, struct, sys, esp, network.
- C long-long type used as bignum implementation (gives 64 bit signed ints).
- Rudimentary WiFi support in station mode.
- Sockets with callbacks.
- Basic GPIO support.
Note that floating-point numbers are not supported.
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.
Then, to build MicroPython 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 0x00000firmware.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
