Paul Sokolovsky f28efa1971 py: Move frozen modules rules from esp8266 port for reuse across ports. 
A port now just needs to define FROZEN_DIR var and add $(BUILD)/frozen.c
to SRC_C to support frozen modules.

Paul Sokolovsky 8ae885a0c6 esp8266/Makefile: Rename SCRIPTDIR to FROZEN_DIR for consistency. 
With FROZEN_MPY_DIR.

Damien George 9526e24234 unix,stmhal,esp8266: When find'ing frozen files follow symbolic links. 
It's useful to be able to use symbolic links to add files and directories
to the set of scripts to be frozen.

Delio Brignoli e2ac8bb3f1 py: Add MICROPY_USE_INTERNAL_PRINTF option, defaults to enabled. 
This new config option allows to control whether MicroPython uses its own
internal printf or not (if not, an external one should be linked in).
Accompanying this new option is the inclusion of lib/utils/printf.c in the
core list of source files, so that ports no longer need to include it
themselves.

Paul Sokolovsky dba40afa70 esp8266/modmachine: Simplify SPI class implementation multiplexing. 
modpybhspi now does the needed multiplexing, calling out to modpybspi
(bitbanging SPI) for suitable peripheral ID's. modmachinespi (previous
multiplexer class) thus not needed and removed.

modpybhspi also updated to following standard SPI peripheral naming:
SPI0 is used for FlashROM and thus not supported so far. SPI1 is available
for users, and thus needs to be instantiated as:

spi = machine.SPI(1, ...)

Damien George 9c04ef2a67 unix,stmhal,esp8266: When find'ing frozen files don't use extra slash. 
This extra forward slash for the starting-point directory is unnecessary
and leads to additional slashes on Max OS X which mean that the frozen
files cannot be imported.

Fixes #2374.

Radomir Dopieralski 8e7dfea803 esp8266/modpybhspi: Add a HSPI module for hardware SPI support 
This module uses ESP8266's SPI hardware, which allows much higher
speeds. It uses a library from

Damien George db80c0ed46 esp8266: Enable frozen bytecode, with scripts in modules/ subdir. 
To start with, the critical scripts _boot.py and flashbdev.py are frozen
to improve performance and reduce RAM consumption.

Saves about 1000 bytes of heap RAM for a bare boot with filesystem.

Paul Sokolovsky 236838a9fc esp8266/Makefile: Enable --verify option for esptool.py write_flash. 
Based on my experience, there's rather non-zero chance to have an image be
flashed incorrectly. As --verify option is now works well in teh latest
esptool.py, enable it by default.

Damien George 45f3416816 esp8266: Enable DHT C-level driver. 
Exposed as esp.dht_readinto.  Probably should go somewhere less
port-specific.

Damien George a6aa35af09 esp8266: Move pyb.info() function to esp module and remove pyb module. 
All functionality of the pyb module is available in other modules, like
time, machine and os.  The only outstanding function, info(), is
(temporarily) moved to the esp module and the pyb module is removed.

Paul Sokolovsky 648333d2d5 esp8266/Makefile: Override abort() when building axtls.

Paul Sokolovsky 6d103b6548 py: Move call_function_*_protected() functions to py/ for reuse. 
They almost certainly needed by any C code which calls Python callbacks.

Damien George df3b1741b6 esp8266: Separate 1-wire timing funcs from Python module to save iRAM. 
esponewire.c contains low-level timing-critical functions that go in
iRAM.  modonewire.c contains Python wrapper code.

Damien George 1a0a323ca8 esp8266: Add initial implementation of machine.UART. 
Currently UART(0) and UART(1) are exposed and only uart.write works.
 2016-04-06 19:45:52 +03:00
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.
 2016-04-03 15:48:46 +03:00
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.
 2016-03-29 21:10:10 +03:00
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.
