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.

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.

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.

6a051a8e0b esp8266/uart: Get ctrl-C working now that event-based REPL is disabled. 2016-04-01 14:53:01 +03:00

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.

fc4c43a72e esp8266: Switch to non event-driven REPL to support paste mode. 2016-04-01 14:22:28 +03:00

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.

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.

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.

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.

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().

c4506ed869 esp8266: Let esp8266 "os" messages go to standard (REPL) UART. 
That's definitely helpful for debugging.

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, "...");

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.
