Damien George 0a2e9650f5 py: Add ability to have frozen persistent bytecode from .mpy files.
The config variable MICROPY_MODULE_FROZEN is now made of two separate
parts: MICROPY_MODULE_FROZEN_STR and MICROPY_MODULE_FROZEN_MPY.  This
allows to have none, either or both of frozen strings and frozen mpy
files (aka frozen bytecode).

Paul Sokolovsky 959ed931a4 esp8266/esp_mphal: call_dupterm_read(): Fix order of deactivating on EOF.
First deactivate, then print diagnostic message.

Paul Sokolovsky 19e3c9d53a esp8266/esp_mphal: Don't swallow exceptions in dupterm's read()/write().
The idea is that if dupterm object can handle exceptions, it will handle
them itself. Otherwise, object state can be compromised and it's better
to terminate dupterm session. For example, disconnected socket will keep
throwing exceptions and dump messages about that.

Paul Sokolovsky 47442d9f52 lib/utils/printf: Rework overriding printer of DEBUG_printf().
By default it uses mp_plat_print, but a port may override it to another
value with MICROPY_DEBUG_PRINTER_DEST.

Damien George 3177ef544f esp8266: In callback helpers, pop nlr_buf on successful call.
nlr_pop must be called if no exception was raised.

Also, return value of these callback helpers is made void because ther
is (currently) no use for it.

Paul Sokolovsky 260b839483 esp8266/scripts/inisetup.py: Set WPA/WPA2 AP mode with a predefined password. 2016-04-12 00:46:04 +03:00
Paul Sokolovsky 40f5ecd3a8 esp8266: Add Python modules for initial configuration.
Main entry point is _boot.py which checks whether FAT FS in flash mountable,
and if so, mounts it. Otherwise, it checks if flash is empty, and if so,
performs initial module setup: makes FAT FS, configures default AP name,
etc. As a last option, if flash is not empty, and could not be mounted,
it means filesystem corruption, and warning message with instructions is
printed in an infinite loop.

Paul Sokolovsky 1cc81ed449 esp8266/modesp: Add freemem() and meminfo() functions.
They call into vendor SDK functions system_get_free_heap_size() and
system_print_meminfo() respectively.

Paul Sokolovsky c734de490a esp8266/main: mp_builtin_open(): Implement, using vfs_proxy_call(). 2016-04-10 16:59:19 +03:00
Damien George 6e87aeb841 esp8266: Implement multistage bootstrap sequence.
Upon start-up, _boot module is executed from frozen files to do early
initialization, e.g. create and mount the flash filesystem. Then
"boot.py" is executed if it exists in the filesystem. Finally, "main.py"
is executed if exists to allow start-on-boot user applications.

This allows a user to make a custom boot file or startup application
without recompiling the firmware, while letting to do early initialization
in Python code.

Based on RFC https://github.com/micropython/micropython/issues/1955.

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
Damien George 96eca22322 esp8266: Make destination for vendor OS debug output soft-configurable.
Use esp.osdebug(None) to disable, or esp.osdebug(uart_id) to send output
to a UART.

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.

Damien George a0cb4eda9a esp8266: Use VM_HOOK to call ets_loop_iter within the VM.
Starting with a divisor of 10, pystone_lowmem gives a score of 256.
2016-04-02 01:34:32 +03:00
Damien George 6a051a8e0b esp8266/uart: Get ctrl-C working now that event-based REPL is disabled. 2016-04-01 14:53:01 +03:00
Damien George fb6cc96951 esp8266/uart: Comment out old, unused rx buffering code.
This was originally used for non-event based REPL processing.  Then it
was unused when event-based processing was activated.  But now that event
based is disabled, and non-event based is back, there has been new ring
buffer code to process the chars.
2016-04-01 14:30:47 +03:00
Paul Sokolovsky fc4c43a72e esp8266: Switch to non event-driven REPL to support paste mode. 2016-04-01 14:22:28 +03:00
Paul Sokolovsky 785cf9a61f esp8266: Support dedicated REPL loop (aka pull-style).
Event-driven loop (push-style) is still supported and default (controlled
by MICROPY_REPL_EVENT_DRIVEN setting, as expected).

Dedicated loop worked even without adding ets_loop_iter(), though that
needs to be revisited later.
2016-04-01 14:02:36 +03:00
Paul Sokolovsky 777232c9a5 esp8266: Disallow recursive calls to REPL.
Before this change, if REPL blocked executing some code, it was possible
to still input new statememts and excuting them, all leading to weird,
and portentially dangerous interaction.

TODO: Current implementation may have issues processing input accumulated
while REPL was blocked.

Paul Sokolovsky 5531437941 esp8266: Move PHY mode constants from modesp to modnetwork. 2016-04-01 12:10:11 +03:00
Damien George 4b597a1c1a esp8266: Reset term_obj on reboot.
Also, term_obj can be NULL if socket enables REPL duplication signalling
before os.dupterm is called, so it should be checked.
2016-03-31 19:56:52 +03:00
Paul Sokolovsky 98af891610 esp8266: Implement input part of dupterm handling.
The idea is following: underlying interrupt-driven or push-style data source
signals that more data is available for dupterm processing via call to
mp_hal_signal_dupterm_input(). This triggers a task which pumps data between
actual dupterm object (which may perform additional processing on data from
low-level data source) and input ring buffer.
2016-03-31 19:49:55 +03:00
Paul Sokolovsky 61fa7c8152 esp8266: Switch back to accumulating input data via ring buffer.
But now it's generic ring buffer implemented via ringbuf.h, and is intended
for any type of input, including dupterm's, not just UART. The general
process work like this: an interrupt-driven input source puts data into
input_buf, and then signals new data available via call to
mp_hal_signal_input().

order (whatever that standard is).
2016-03-30 11:35:03 +03:00
Paul Sokolovsky d88250c06e esp8266: Reduce heap size for now to avoid random segfaults on WiFi connect. 2016-03-29 21:14:41 +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 402a743821 esp8266/esp_mphal: Add support for debug UART-only output.
Helpful when debugging dupterm support (because otherwise all output is
spooled to dupterm too).

To use:

mp_printf(&mp_debug_print, "...");

Damien George 71d40f132d esp8266: Zero out fs_user_mount state on (soft) reset.
Otherwise device stays mounted on soft reset and leads to corruption

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.

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
