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.
Review feedback
Fix typo
Fixes:
* Removed spurious \0 bytes being sent to the client in many cases.
* Properly terminated 404 header.
* Now including Content-length: header for index.html (including built-in).
Clients otherwise had to wait for their own timeout before considering
the page load complete, which resulting in an unpleasant sluggish
experience.
* Switched form submission to GET, as iOS sometimes does not include the
body in the same packet as the POST header, which led to the module
not finding the form values.
* Added redirect after form submission to avoid blank-page-in-browser.
* Moved common "enduser_setup" prefix to a lua_pushfstring() to reduce
string literal overhead.
* Replaced cached lua_State* with calls to lua_getstate(), as in other
modules.
* Fixed broken appending of MAC to the SSID.
* Fixed up macro definitions to not break `if` clauses unintentionally.
Enhancements:
* Support for scanning for available WiFi networks, and picking from the list.
* Support for retrieving the current WiFi station status.
* Added "manual" mode, where the module does not (re)configure the AP setup,
nor shut down automatically. Default is still automatic, as before.
* Updated docs for new `enduser_setup.manual()` function.
To create a size led long buffer:
buffer = ws2812.newBuffer(size);
To fill the buffer:
buffer:fill(g, r, b)
To get a particular led color:
g, r, b = buffer:get(index)
To set a particular led color:
buffer:set(index, g, r, b);
To send the buffer:
buffer:write(pin);
Module creation & registration now made a lot simpler. In essence,
each module file is now self-contained and only needs a
NODEMCU_MODULE(MYNAME, "myname", myname_map, luaopen_myname);
line to both be automatically recognised by the Lua initialization
as well as honor the LUA_USE_MODULES_MYNAME #define.
As per #810 & #796, only LUA_OPTIMIZE_MEMORY=2 & MIN_OPT_LEVEL=2 are
supported when building. This commit effects that limitation.
With this change modules/auxmods.h no longer needs to be updated for
every new module, nor do module writers need to cater for a hypothetical
LUA_OPTIMIZE_MEMORY < 2 scenario.
There was only one genuine use of this macro, all other places were
using it only as a necessary compensation. While this was fine as long as
it was the first meg of flash which was mapped, it became incorrect and
quite dangerous whenever this assumption did not hold (such as when
running from the second slot in an OTA scenario).
The flash API now uses actual addresses, not translated/mapped
addresses, and the users of this API have been adjusted accordingly.
This makes the flash API work correctly regardless of what flash mapping
is in use.
The old macro is still available under the new name
INTERNAL_FLASH_MAPPED_ADDRESS, and this is used to detect flash writes
where the source is mapped flash (and thus has to be bounced), and to
adjust the _flash_used_end linker symbol when used with
flassh_find_sector() by the filesystem code. The latter usage is not
OTA-proof, but in an OTA scenario the filesystem needs a fixed location
anyway and thus would not use this code path.
When lua assertions are enabled, normal operation results in many:
lobject.c:88: (((t1)->tt) == 4)
lobject.c:88: (((t2)->tt) == 4)
lobject.c:88: (((t1)->tt) == 4)
lobject.c:88: (((t2)->tt) == 4)
lobject.c:88: (((t1)->tt) == 4)
lobject.c:88: (((t2)->tt) == 4)
It comes from using the pvalue() macro for 3 pointer types, where
pvalue() also checks the type of pointer and complains through the
assertion where the type == 4 (TLIGHTUSERDATA).
Use the correct macro according to the type of data being compared
to eliminate this assertion error.

Master contained two OW changes one of which was already reimplemented in dev using the
correct macros. The second was from hazarkarabay (f6d0c0c) that onewire_search()
returns a device address vector even when no device is found. I've reimplemented this
but using the correct index, rom_byte_number, rather than declaring a new temp index i.
