Damien George 1ed3356540 py/py.mk: Make berkeley-db C-defs apply only to relevant source files. 
Otherwise they can interfere (eg redefinition of "abort") with other source
files in a given uPy port.

Damien George b6c7e4b143 all: Use full path name when including mp-readline/timeutils/netutils. 
This follows the pattern of how all other headers are now included, and
makes it explicit where the header file comes from.  This patch also
removes -I options from Makefile's that specify the mp-readline/timeutils/
netutils directories, which are no longer needed.

Damien George 1808b2e8d5 extmod: Remove MICROPY_FSUSERMOUNT and related files. 
Replaced by MICROPY_VFS and the VFS sub-system.

Damien George 8beba7310f extmod/vfs_fat: Remove MICROPY_READER_FATFS component. 2017-01-30 12:26:07 +11:00
Paul Sokolovsky 7a7516d40d extmod/machine_signal: Implement "signal" abstraction for machine module. 
A signal is like a pin, but ca also be inverted (active low). As such, it
abstracts properties of various physical devices, like LEDs, buttons,
relays, buzzers, etc. To instantiate a Signal:

pin = machine.Pin(...)
signal = machine.Signal(pin, inverted=True)

signal has the same .value() and __call__() methods as a pin.

Damien George dcb9ea7215 extmod: Add generic VFS sub-system. 
This provides mp_vfs_XXX functions (eg mount, open, listdir) which are
agnostic to the underlying filesystem type, and just require an object with
the relevant filesystem-like methods (eg .mount, .open, .listidr) which can
then be mounted.

These mp_vfs_XXX functions would typically be used by a port to implement
the "uos" module, and mp_vfs_open would be the builtin open function.

This feature is controlled by MICROPY_VFS, disabled by default.

Damien George d4464b0050 py/py.mk: Add CFLAGS_MOD flag to set config file for FatFs. 2017-01-27 13:19:10 +11:00
Damien George 9f04dfb568 py: Add builtin help function to core, with default help msg. 
This builtin is configured using MICROPY_PY_BUILTINS_HELP, and is disabled
by default.

Paul Sokolovsky d02f6a9956 extmod/modutimeq: Refactor into optimized class. 
import utimeq, utime
    # Max queue size, the queue allocated statically on creation
    q = utimeq.utimeq(10)
    q.push(utime.ticks_ms(), data1, data2)
    res = [0, 0, 0]
    # Items in res are filled up with results
    q.pop(res)

Damien George f76b1bfa9f py: Add inline Xtensa assembler. 
This patch adds the MICROPY_EMIT_INLINE_XTENSA option, which, when
enabled, allows the @micropython.asm_xtensa decorator to be used.

The following opcodes are currently supported (ax is a register, a0-a15):

    ret_n()
    callx0(ax)
    j(label)
    jx(ax)

    beqz(ax, label)
    bnez(ax, label)
    mov(ax, ay)
    movi(ax, imm) # imm can be full 32-bit, uses l32r if needed

    and_(ax, ay, az)
    or_(ax, ay, az)
    xor(ax, ay, az)
    add(ax, ay, az)
    sub(ax, ay, az)
    mull(ax, ay, az)

    l8ui(ax, ay, imm)
    l16ui(ax, ay, imm)
    l32i(ax, ay, imm)
    s8i(ax, ay, imm)
    s16i(ax, ay, imm)
    s32i(ax, ay, imm)
    l16si(ax, ay, imm)
    addi(ax, ay, imm)

    ball(ax, ay, label)
    bany(ax, ay, label)
    bbc(ax, ay, label)
    bbs(ax, ay, label)
    beq(ax, ay, label)
    bge(ax, ay, label)
    bgeu(ax, ay, label)
    blt(ax, ay, label)
    bnall(ax, ay, label)
    bne(ax, ay, label)
    bnone(ax, ay, label)

Upon entry to the assembly function the registers a0, a12, a13, a14 are
pushed to the stack and the stack pointer (a1) decreased by 16.  Upon
exit, these registers and the stack pointer are restored, and ret.n is
executed to return to the caller (caller address is in a0).

Note that the ABI for the Xtensa emitters is non-windowing.
 2016-12-09 17:07:38 +11:00
Damien George 8e5aced1fd py: Integrate Xtensa assembler into native emitter. 
The config option MICROPY_EMIT_XTENSA can now be enabled to target the
Xtensa architecture with @micropython.native and @micropython.viper
decorators.

Damien George 612599587b py: Factor out common code from assemblers into asmbase.[ch]. 
All assemblers should "derive" from mp_asm_base_t.

Paul Sokolovsky 8f5bc3ffc0 stmhal/moduselect: Move to extmod/ for reuse by other ports. 2016-11-21 00:05:56 +03:00
Damien George 66d955c218 py/lexer: Rewrite mp_lexer_new_from_fd in terms of mp_reader. 2016-11-16 18:13:51 +11:00
Damien George e5ef15a9d7 py/lexer: Provide generic mp_lexer_new_from_file based on mp_reader. 
If a port defines MICROPY_READER_POSIX or MICROPY_READER_FATFS then
lexer.c now provides an implementation of mp_lexer_new_from_file using
the mp_reader_new_file function.

Damien George 511c083811 py/lexer: Rewrite mp_lexer_new_from_str_len in terms of mp_reader_mem. 2016-11-16 18:13:50 +11:00
Damien George 6b239c271c py: Factor out persistent-code reader into separate files. 
Implementations of persistent-code reader are provided for POSIX systems
and systems using FatFS.  Macros to use these are MICROPY_READER_POSIX and
MICROPY_READER_FATFS respectively.  If an alternative implementation is
needed then a port can define the function mp_reader_new_file.

Damien George 6810f2c134 py: Factor persistent code load/save funcs into persistentcode.[ch]. 2016-11-16 16:14:14 +11:00
Damien George 659b06b250 py/*.mk: Replace uses of 'sed' with $(SED). 2016-11-15 16:09:43 +11:00
Damien George bdf33bc136 py: Move frozen bytecode Makefile rules from ports to common mk files. 
Now, to use frozen bytecode all a port needs to do is define
FROZEN_MPY_DIR to the directory containing the .py files to freeze, and
define MICROPY_MODULE_FROZEN_MPY and MICROPY_QSTR_EXTRA_POOL.

Paul Sokolovsky f00ecdb54d extmod/moduos_dupterm: Renamed to uos_dupterm. 
As part of file naming clean up (moduos_dupterm doesn't implement a
full module, so should skip "mod" prefix, similar to other files in
extmod/).
 2016-10-26 02:08:37 +03:00
Paul Sokolovsky b440307b4a py/py.mk: Automatically add frozen.c to source list if FROZEN_DIR is defined. 
Now frozen modules generation handled fully by py.mk and available for reuse
by any port.
