Johny Mattsson 6b6456be47 Major cleanup of module registration. 
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.

Thomas Soëte 4fd552fcaf Better timings for 160MHz too. 
Values measured:
@80MHz:
	T0H: 337ns, Period: 1.274us
	T1H: 687ns, Period: 1.25us

@160MHz:
	T0H: 349ns, Period: 1.262us
	T1H: 700ns, Period: 1.276us

Thomas Soëte c2f12a3b05 Better timings for WS2812 (measured 345ns/695ns, instead of 340ns/600ns) 2015-11-08 22:45:12 +01:00
Johny Mattsson d2ac5f1712 Changed os_intr_xxx to ets_intr_xxx. 
The os_intr_xxx macros no longer exist in the SDK.

Konrad Beckmann 6538d22d1f Improved ws2812 implementation 
- 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).

vowstar 3430e5f826 Add __attribute__((optimize("O2"))) to ws2812 module. 2015-06-20 01:40:45 +08:00
makefu c29edf7a22 app/modules/ws2812.c: re-add ws2812.write() 
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

Wolfram Ladurner ff85cf4371 fixes issue #321 "ws2812.writergb scrambles buffer" reported by makefu. 
Don't modify Lua-internal lstring - use a copy instead.

Markus Gritsch 8432e8c8be Changed the ws2812 byte order from GRB to RGB 
There seems to be interest in using the more intuitive RGB byte order to
specify the LED color. Also fixed the documentation.
