Paul Sokolovsky 6ab2c5e6cc lib/interrupt_char: Factor out typical Ctrl+C handling from esp8266 port.
Utility functions for keyboard interrupt handling, to be reused across
(baremetal) ports.

Damien George 34e0198436 esp8266: Extend system microsecond counter to 64-bits; use in ticks_ms.
So now ticks_ms can count up to the full 30 bits.  Fixes issue #2412.

Paul Sokolovsky 4b3f1d712b esp8266/esp_mphal: Add tentative change to mp_hal_stdin_rx_chr() to wait IRQ.
Instead of busy-looping waiting for UART input. Not enabled by default,
needs more testing.

Paul Sokolovsky 015774a04f esp8266/modmachinewdt: Add .deinit() method. 2016-09-03 20:45:11 +03:00
Paul Sokolovsky f2a21a2489 esp8266/esp_mphal: No longer disable watchdog on startup.
Disabling it was an omission from early development stages.

Paul Sokolovsky 64ad838fde esp8266/esp_mphal: Implement libc's errno.
Using __errno() function, and redirect it to use mp_stream_errno from
stream module. This is pre-requisite for integrating with 3rd-party libs,
like BerkeleyDB.

Paul Sokolovsky 380561836d esp8266/esp_mphal: Properly handle dupterm EOF after switching to readinto(). 2016-07-05 14:18:12 +03:00
Paul Sokolovsky a22b6ebff1 esp8266/esp_mphal: call_dupterm_read: Use readinto() method.
It's memory fragmentation hazard to allocate 1-char string each time by
calling read() method.

Damien George 4b37e775ea extmod/machine_i2c: Redo mp_hal_pin macros to use open_drain and od_low.
mp_hal_pin_config_od is renamed mp_hal_pin_open_drain, and mp_hal_pin_low
is mp_hal_pin_od_low.

Paul Sokolovsky 2b05b60bbc esp8266/esp_mphal: mp_uos_dupterm_deactivate() may raise exception.
So, keep call to it protected via NLR still.

Paul Sokolovsky 4681b86850 esp8266/esp_mphal: Handle Ctrl+C from dupterm (e.g. WebREPL). 2016-05-24 01:37:56 +03:00
Paul Sokolovsky 116eeee6db esp8266/esp_mphal: Fix NLR buffer leak in call_dupterm_read(). 2016-05-24 01:30:28 +03:00
Paul Sokolovsky 0ab372585f extmod/moduos_dupterm: Dumpterm subsystem is responsible for closing stream.
Make dupterm subsystem close a term stream object when EOF or error occurs.
There's no other party than dupterm itself in a better position to do this,
and this is required to properly reclaim stream resources, especially if
multiple dupterm sessions may be established (e.g. as networking
connections).

Paul Sokolovsky 3d830415bc esp8266/esp_mphal: Add ets_esf_free_bufs(), etc. functions.
Returning free number of various WiFi driver packet buffers.

Damien George 67a6d31955 esp8266: Allow GPIO16 to be used as a pin in the uPy pin HAL.
Now I2C works with GPIO16 as the SCL or SDA pin.
2016-04-22 10:35:26 +01:00
Damien George a2d5d84ecc esp8266: Convert mp_hal_pin_obj_t from pin ptr to simple integer.
Most pin I/O can be done just knowing the pin number as a simple
integer, and it's more efficient this way (code size, speed) because it
doesn't require a memory lookup to get the pin id from the pin object.

If the full pin object is needed then it can be easily looked up in the
pin table.

Damien George d4f4cb6a24 esp8266/esp_mphal: Remove mp_hal_feed_watchdog.
It doesn't do anything and is not needed.  ets_loop_iter/ets_event_poll
now take care of feeding the WDT.

Paul Sokolovsky 6f3b9933bd esp8266/esp_mphal: Protect dupterm_task_handler() from recursive exec. 2016-04-17 18:11:04 +03:00
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 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 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().

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, "...");

Paul Sokolovsky c961889e34 esp8266: Add basic support for duplicating REPL output. 2016-03-29 11:13:32 +03:00
Damien George e673714cfe esp8266: Make mp_hal_delay_us work with new event framework. 2016-03-23 13:01:21 +02:00
Paul Sokolovsky a099bfe89c esp8266/esp_mphal: Add higher-level event polling function.
ets_event_poll() polls both system events and uPy pending exception.

Paul Sokolovsky d3a4d39687 esp8266: Support raising KeyboardInterrupt on Ctrl+C. 2016-03-05 22:01:27 +02:00
Paul Sokolovsky 8ab16b6af0 esp8266: Add custom _assert() function.
Enabling standard assert() (by removing -DNDEBUG) produces non-bootable
binary (because all messages go to .rodata which silently overflows).
So, for once-off debugging, have a custom _assert().

Paul Sokolovsky a4c8ef9d16 esp8266: Reset "virtual RTC" on power on.
Initialize RTC period coefficients, etc. if RTC RAM doesn't contain valid
values. time.time() then will return number of seconds since power-on, unless
set to different timebase.

This reuses MEM_MAGIC for the purpose beyond its initial purpose (but the whole
modpybrtc.c need to be eventually reworked completely anyway).

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.
