Damien George 632d8efa05 esp8266: Add PWM support. 
PWM implementation uses a timer and interrupts (FRC1), taken from
Espressif's/NodeMCU's implementation and adapted for our use.

8 channels are supported, on pins 0, 2, 4, 5, 12, 13, 14, 15.

Usage:

    import machine
    pwm0 = machine.PWM(machine.Pin(0))
    pwm0.freq(1000)
    pwm0.duty(500)

Frequency is shared (ie the same) for all channels.  Frequency is
between 1 and 1000.  Duty is between 0 and 1023.

Damien George 82b95f625e esp8266: Implement software SPI class. 
Supports speeds up to 500k baud, polarity=0/1, phase=0/1, and using any
pins.  Only supports MSB output at the moment.

Paul Sokolovsky adfe4ff72a esp8266: Support CFLAGS_EXTRA. 2016-01-08 01:30:20 +02:00
Paul Sokolovsky 73ff0687f2 lib/utils/printf: Move from stmhal/ . 
This file contains various MicroPython-specific helper functions, so isn't
good fit for lib/libc/.
 2015-11-10 18:58:58 +02:00
Paul Sokolovsky 0ec51441de stmhal: pyexec.c is common module, move to lib/utils/ . 2015-10-31 19:35:10 +03:00
Paul Sokolovsky 0dbd928cee Makefiles: Remove duplicate object files when linking. 
Scenario: module1 depends on some common file from lib/, so specifies it
in its SRC_MOD, and the same situation with module2, then common file
from lib/ eventually ends up listed twice in $(OBJ), which leads to link
errors.

Make is equipped to deal with such situation easily, quoting the manual:
"The value of $^ omits duplicate prerequisites, while $+ retains them and
preserves their order." So, just use $^ consistently in all link targets.

Paul Sokolovsky e0f5df579b all: Make netutils.h available to all ports by default. 
Generally, ports should inherit INC from py.mk, append to it, not
overwrite it. TODO: Likely should do the same for other vars too.
 2015-10-19 18:32:42 +03:00
Damien George 229b908d2e esp8266: Remove "time" command from deploy target. 2015-09-12 22:22:30 +01:00
Paul Sokolovsky b19d273beb esp8266: Allow to easily override programming baudrate. 2015-07-04 00:36:10 +03:00
Paul Sokolovsky ee3fec3167 esp8266: Add skeleton "network" module. 
MicroPython "network" module interface requires it to contains classes
to instantiate. But as we have a static network interace, make WLAN()
"constructor" just return module itself, and just make all methods
module-global functions.

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

Damien George 0b32e50365 stmhal: Make pybstdio usable by other ports, and use it. 
Now all ports can use pybstdio.c to provide sys.stdin/stdout/stderr, so
long as they implement mp_hal_stdin_* and mp_hal_stdout_* functions.

Paul Sokolovsky 8fff7f8d38 esp8266: Add "reset" target to Makefile.

automatically executed. And to get back to bootloader, do "make reset".

Damien George d96e6b14c9 esp8266: Make default ESP_SDK variable work correctly. 
When esp-open-sdk is built with STANDALONE=y (the default) then ESP_SDK
is set to the correct value, so that "make" just works.

Damien George fbea810043 esp8266: Change bignum from mpz to longlong; move some rodata to iram. 
Some rodata items can go in iram/irom segment, but not others.  With
this patch ESP now has 24256 bytes of heap ram.  It passes 228 out of
248 tests from tests/basics directory.
