New driver is a three-way merger between Espressif's esp8266-rtos-sdk example
driver, Espressif's esp32-rtos-sdk not-example driver, and the previous
NodeMCU driver, plus some general clean-ups.
Basic interactivity is now available on the ESP32!
A fair bit of reshuffling with include paths and overrides was necessary, as
the two RTOS SDKs (ESP8266 and ESP32) don't have the same header structure
(or even libraries for that matter). Uses the xtensa-esp108-elf toolchain
to build.
Completely untested beyond linking, as I still can't flash the ESP32 module
I have :( I'd be most surprised if it does anything useful at this point
considering I've spent almost no time on the linker script or UART setup.
Anything using espconn has been ifdef'd out since espconn is not (and
probably will not be) available. Notably this includes the entire net module
as well as coap, mqtt and enduser_setup.
Many (most?) hardware bus drivers and related modules are also ifdef'd
out for now due to hardware differences. Functions surrounding sleep,
rtc and RF modes have also been hit by the ifdef hammer. Grep'ing for
__ESP8266__ and/or FIXME is a quick way of finding these places. With
time I hope all of these will be reinstated.
This compiles, links, and starts the RTOS without crashing and burning.
Lua environment does not yet start due to the different task architecture.
Known pain points:
- task implementation needs to be rewritten for RTOS (next up on my TODO)
- secure espconn does not exist, all secure espconn stuff has been #if 0'd
- lwip now built from within the RTOS SDK, but does not appear to include
MDNS support. Investigation needed.
- there is no access to FRC1 NMI, not sure if we ever actually used that
however. Also #if 0'd out for now.
- new timing constraints introduced by the RTOS, all use of ets_delay_us()
and os_delay_us() needs to be reviewed (the tsl2561 driver in particular).
- even more confusion with ets_ vs os_ vs c_ vs non-prefixed versions.
In the long run everything should be switched to non-prefixed versions.
- system_set_os_print() not available, needs to be reimplemented
- all the RTOS rodata is loaded into RAM, as it apparently uses some
constants while the flash isn't mapped, so our exception handler can't
work its magic. This should be narrowed down to the minimum possible
at some point.
- with each task having its own stack in RTOS, we probably need change
flash-page buffers from the stack to the heap in a bunch of places.
A single, shared, page buffer *might* be possible if we limit ourselves
to running NodeMCU in a single task.
- there's a ton of junk in the sdk-overrides now; over time the core code
should be updated to not need those shims
- Stop fighting against the SDK in terms of owning/writing the init_data block.
NodeMCU included a default init_data block because originally the SDK did
not, but by now it's not needed.
- Expose a way to reconfigure the ADC mode from Lua land. With most people
using the cloud builder and not able to change the #define for byte 107
this has been a pain point.
- Less confusion about which init_data has been used. Lua code can now simply
state what mode it wants the ADC to be in, and not worry about the rest of
the init_data complexities such as the init_data changing location due to
flashing with wrong flash_size setting, or doing/not doing a chip-erase
before loading new NodeMCU firmware.
Merging as suggested by @TerryE (and squashing at the same time. Turns out that this feature is enabled for this repo).

Module to handle rotary decoders
Eliminate ROTARY_DEBUG
Remove unused file
Eliminate a malloc call
Cleaned up the register code. Now 0x114 bytes
Fix bug with clearing bits in one case
Fix the type in the #define name
AFAIK no one uses the wifi.startsmart() and wifi.stopsmart(). Removing
them frees up an extra 20-25K of Flash to use as filesystem. So I have
added a new config define WIFI_SMART_ENABLE which is enabled by default
so the default functionality is the same, but if this is commented out
then this code is omitted.
I have also removed wofs and upgrade from this build as we no longer
support these.

Addressed review comments
Add the binsize return
As with the last commit this rolls up the follwowing, but include the various
review comments on the PR.
- **Documentation changes**. I've added the taks FAQ as a stub new Extension
developer FAQ, and split the old FAQ into a Lua Developer FAQ and a Hardware
FAQ.
- **Tasking I/F**. New `app/task/Makefile`, `app/task/task.c`,
`app/include/task/task.h` and `app/Makefile` as per previous commit. Cascade
changes to `app/driver/uart.c`, `app/include/driver/uart.h`,
`app/user/user_main.c` and `app/modules/node.c`
- **GPIO Rework** to `app/modules/gpio.c` and `pin_map.[hc]`, `platform.[hc]`
in `app/platform`
- **Other Optimisations** Move the `platform_*_exists()` from
`app/platform/common.c` to static inline declarations in `platform.h` as
this generates faster, smaller code. Move lgc.a routines out of iram0.
packed structures in strings. Very useful for network protocol
packing/unpacking. The docs are directly converted from the original.
