Thomas Soëte 8866297c6d Remove buffer:write() as ws2812.write() handles buffers (#1408) 2016-07-20 23:04:33 +02:00
Thomas Soëte 854ad7c80f Handle two WS2812 strips in parallel using the two UARTs through GPIO2 and TXD0 (#1310) 2016-07-20 22:28:47 +02:00
Konrad Hübner 500bbceded added fadeIn, faceOut and shift to ws2812 module (#1343)
* 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

Thomas Soëte 0577c8af0f Finalize work on ws2812 module
* 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

Thomas Soëte 47b44229bf ws2812 data buffer
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);

Thomas Soëte 51bb8a50ba Rewrite code to use UART1 instead of bit-banging.
It allows keeping interrupts enabled but force to use GPIO2.

Johny Mattsson 4e8ef87d03 Reworked module registration, removed modules.h
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.

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.
