The PR removed the bulk of non-newlib headers from the NodeMCU source base.
app/libc has now been cut down to the bare minimum overrides to shadow the
corresponding functions in the SDK's libc. The old c_xyz.h headerfiles have been
nuked in favour of the standard <xyz.h> headers, with a few exceptions over in
sdk-overrides. Again, shipping a libc.a without headers is a terrible thing to do. We're
still living on a prayer that libc was configured the same was as a default-configured
xtensa gcc toolchain assumes it is. That part I cannot do anything about, unfortunately,
but it's no worse than it has been before.
This enables our source files to compile successfully using the standard header files,
and use the typical malloc()/calloc()/realloc()/free(), the strwhatever()s and
memwhatever()s. These end up, through macro and linker magic, mapped to the
appropriate SDK or ROM functions.
* ws2812 effects and color utils modules added
* Added documentation for new modules to mkdocs.yml
* changed mode option to string, documentation, default modules fixed
* updated user_modules.h
* Add load/dump/mix/power operations on the buffer object
* Calculate the pixel value in mix and then clip to the range.
* Fixed the two wrong userdata types
* Added a couple more useful methods
* Add support for shifting a piece of the buffer.
* Fix a minor bug with offset shifts
* added fadeIn, faceOut and shift to ws2812 module
* improvements to rotate, unified fade method
shift renamed to rotate and usage of more efficient memory operations.
fadeIn and fadeOut unified into fade method with optional parameter for direction.
* rename method to "shift" with optional mode parameter
* Fix bug on first write
Pin is 'HIGH' at reset, so we need to pull it down and generate a
reset.
* Move init code to flash section, not needed to be in iram.
* Remove pin choice in API
* Remove lock in ws2812_buffer_write
* Remove naked malloc
* Drop ws2812_writergb
* Drop support of ws2812.buffers to ws2812_writegrb should use ws2812.buffers:write
* Add support for <>3 colors per leds strips (RGBW)
* Remove ICACHE_FLASH_ATTR
* Add static const on _uartData to avoid initialization penalty
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.
- Fixes the "first led problem" (#534#487).
- Adds support for 160MHz mode.
- Optimized timings. Time to write pixels is reduced by about 25%
This is useful when having a large amount of chained LEDs (>500).
Add the original ws2812.write() function which does not scramble the
buffer while preserving the 'new' ws2812.writergb.
With this everybody should be happy again
