- micropython is designed to run on a machine with 192 kilobytes of
RAM and perhaps a megabyte of FLASH. The controller can execute
read-only code directly from FLASH. There is no dynamic linker in this
environment. (It also has a UNIX port).
- However it does include a full Python parser and REPL, so the board
can be programmed without a separate computer as opposed to, say,
having to upload bytecode compiled on a regular computer.
- It's definitely going to be a subset of Python. For example,
func.__name__ is not supported - to make it more micro?
- They have a C API. It is much different than the CPython C API.
- It mas more than one code emitter. A certain decorator causes a
function to be compiled to ARM Thumb code instead of bytecode.
- It even has an inline assembler than translates Python-syntax ARM
assembly (to re-use the same parser) into machine code.
