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.

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.

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.

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
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().

pwm0.duty(500)
Frequency is shared (ie the same) for all channels. Frequency is
between 1 and 1000. Duty is between 0 and 1023.

Original BootROM function are renamed, prefixed with underscore. There's
a switch which allows to use forward calls to them, for compatibility
testing.
The implementation also includes workarounds for hardware timer handler,

interface object. Individual operations are then methods of interface
object. Some operations require i/f of specific type (e.g. .connect()
makes sense only for STA), other are defined for any (e.g. .ifconfig(),
.mac()).
