Damien George 1a0a323ca8 esp8266: Add initial implementation of machine.UART.
Currently UART(0) and UART(1) are exposed and only uart.write works.

Paul Sokolovsky 919b70b7ec esp8266: Switch back to flashing combined firmware (single file).
With gap between segments minimized, there's not much padding to flash,
so no big speed overhead.

Paul Sokolovsky 8d2bcaf3cd esp8266: Minimize gap between Inst/DataRAM segments and FlashROM segment.
With .rodata being in FlashROM now, gap can be much smaller now. InstRAM
can be max 32K, and with segment headers, that already makes it more than
32K. Then there's some .data still, and the next Flash page boundary is
0x9000. That figure should be more or less future-proof.

TODO: Refactor makeimg to take FlashROM segment offset from file name.

Paul Sokolovsky ef0c5db2ed esp8266: Move .rodata where it belongs with -mforce-l32 help. 2016-04-03 00:51:51 +03:00
Paul Sokolovsky c4506ed869 esp8266: Let esp8266 "os" messages go to standard (REPL) UART.
That's definitely helpful for debugging.

Paul Sokolovsky b01a373adb esp8266: deploy: Use --flash_size=8m option to esptool.py.
Most esp8266 modules have at least 1MB (8Mbit) of flash. If not set, vendor
functions allow to access only first 512K.

Paul Sokolovsky 374654f2b8 esp8266: Enable FatFs support. 2016-03-27 17:13:47 +03:00
Damien George 3962766be0 esp8266: Add esp.neopixel_write function to bit-bang WS2812 data. 2016-03-26 10:55:21 +02:00
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 9d7b871f58 esp8266: Store frozen modules in FlashROM.
Requires special lexer to access their contents.

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.

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.
Just always keep jumper in bootloader position. After flashing, uPy
automatically executed. And to get back to bootloader, do "make reset".
2015-01-31 00:51:39 +02:00
Paul Sokolovsky 6ec650b41f esp8266: Add "esp" module with esp8266-specific "cooperative" networking.
So far implements .scan(lambda x: print(x)) function to scan for WiFi access
points.

Damien George 9ddbe291c4 py: Add include guards to mpconfig,misc,qstr,obj,runtime,parsehelper. 2014-12-29 01:02:19 +00:00
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.
