* Add basic support for SAMD51, used in M4 line from Adafruit. Support is only based on Adafruit ItsyBitsy M4 Express, since it’s the only M4 board I have.
* Pin verification from ItsyBitsy's variant.h + mixup between I2C and SPI

scale16 returns a uint16_t and it doesn't seem necessary to upcast.

* Add global brightness support for ADA102 and SK9822
* Move brightness computation outside of the loop

The documentation for FASTLED_RMT_BUILTIN_DRIVER says that you should
#define FASTLED_RMT_BUILTIN_DRIVER
before `#include`ing FastLED if you have custom RMT applications running.
Without any non-zero value, this results in the following compile error:
/path/to/Arduino/libraries/FastLED/platforms/esp/32/clockless_esp32.h: In member function 'void ClocklessController<DATA_PIN, T1, T2, T3, RGB_ORDER, XTRA0, FLIP, WAIT_TIME>::initRMT()':

(#650)
|

This mostly builds on previous work for SparkCore STM32103 (Cortex M3),
and patches from Evey Quirk.
Unfortunately, stm32duino distribution does not include a header
with definitions for CoreDebug registers and flags etc. (used in )
so they were added to a newly created cm3_regs.h from
https://github.com/ARM-software/CMSIS/blob/master/CMSIS/Include/core_cm3.h
[v2: changed PIN numbers to be int]

`str` macro conflicts with any function or method that has the same
name ignoring namespaces and class names. Most noticeably it conflicts
with `std::basic_stringstream::str()`. Also there is no usage of the
`str` macro in the library.

This adds the following keywords:
* `CRGBArray`
* `clearData`
* `setMaxPowerInMilliWatts`
* `setMaxPowerInVoltsAndMilliamps`
* `setMaxRefreshRate`
This fixes #642.

Exit early if the interrupt is for another channel which is used by something else than FastLED.
This is needed if we use FASTLED_RMT_BUILTIN_DRIVER and lower FASTLED_RMT_MAX_CHANNELS in order to free some rmt channels for something else.
In this case doneOnChannel() is called for all rmt channels even if they don't belong to FastLED. So exit early in this case before the esp32 notices and reboots on its own.

* Support for ESP32
Credit to Rina Shkrabova for the first cut.
* Clean up interrupt handling
I think there was actually an error in the interrupt enabling/disabling, but I also cleaned it up so that it is more clear how interrupts are handled.
* Better interrupt handling
* Added RMT version
Not fully portable yet, though. The timing numbers are hard-wired for WS2812, and the RMT channel is also hard-wired.
* Fixed the timing
Timing is now computed from T1, T2, amd T3 instead of being hard-wired.
* Better buffer management
The RMT signal is sent in 10-pixel chunks, using double-buffering to hide the latency when possible. Also: assign RMT channels sequentially.
* Total rewrite using Martin's code
* Better comments
* Fixed the timing calculation
We were not doing the conversion from ESP32 cycles to RMT cycles correctly. Now it all works!
* Added Martin's changes
* Removed confusing comments
* Added my name!
* Fixed ESP32 compile problem
On ESP platforms the dev kit provides the function __cxa_pure_virtual, so there is no need to define it.
* honor WAIT_TIME
for chipsets that need it (for example TM1829)
* Better interrupt handling
Suggested by @h3ndrik : allocated the interrupt once at the initialization and then just turn it on and off. This is the strategy that the ESP32 core uses also.
* Major refactoring
Two major changes to the RMT driver. First, I realized that we can have only one interrupt handler attached to the RMT peripheral, so it needs to be able to handle all of the attached strips. To accomplish this, I store each ClocklessController in an array indexed by its RMT channel. The interrupt handler can then take the channel that triggered it and index into the array to get the right controller.
The second major change is that I replaced all of the explicit bit twiddling of the RMT configurartion with calls to the proper functions in ESP32 core. That should make the code more stable if the core changes.
* Fixed the interrupt dispatch
Since the interrupt handler is global for all channels, we need to store not just the controller, but also the buffer refill function for each strip.
* Added a demo
This version of DemoReel100 spins off a separate task on core 0 that just performs the FastLED.show() operations. Regular code running on core 1 (the default for Arduino) signals this task to request a show().
* Avoid unnecessary timeouts
Replaced a 500ms delay in the show task with MAX_DELAY. There's really no point in timing out (and crashing the program) just because the application hasn't called show.
* Parallel output
Reworked the code again in order to support parallel output, which is now the default mode. You can also now ask it to use the built-in RMT driver if you have other parts of your code that need the RMT peripheral.
Two #defines control choices -- put either or both of these before including FastLED.h:
#define FASTLED_RMT_CORE_DRIVER
Uses the ESP core RMT driver. To do this, though, it allocates a big buffer to hold all of the pixel bits, so there is a memory and compute cost.
#define FASTLED_RMT_SERIAL_OUTPUT
Force serial output of each strip.
* Documentation
Describing the implementation and the compile-time switches
* Removing files that should not be there
* Fixed synchronization
The previous checkin had bugs in the syncronization that caused problems in parallel mode when strips are different lengths.
* Fixed a stupid bug
Made the code bullet-proof in a few ways, but most importantly fixed a terrible integer underflow bug in the code that fills the RMT buffer.
* Another major overhaul
The big change in this version is the ability to support more than 8 controllers. Instead of assigning RMT channels to controllers in a fixed mapping, channels are assigned on the fly, allowing the driver to reuse channels as they become available.
* Oops
Didn't mean to check these in.
* Fixed built-in driver mode
Fixed the code so that it works with the built-in RMT driver. There's nothing special to do to enable it -- just #define FASTLED_RMT_BUILTIN_DRIVER true
* Cleanup
Fixing some documentation and configuration stuff
* Rewrite of fastpin
I've been needing to rewrite fastpin_esp32.h for the ESP32 ports and masks. This file also makes sure we don't use pins that won't work, even with clockless chips like the WS2812.
* Got rid of tabs
Which were making the code ugly.
* Minor tweaks
Added proper definitions for port() and toggle() to use the GPIO.out register. Changed the pin number test to avoid unnecessary conditions.
* Allow TX and RX pins
* Fixed pin access methods
This should be the right set of definitions -- consistent with the other platforms.
* Experimental
Do not merge this code
* Change pixel buffering
The previous version of this code saved a copy of the PixelController every time show() is called. It appears that this causes massive memory fragmentation, eventually locking up the processor. This new version saves the pixel data is a separate buffer that is allocated only one time.
* Some rearranging of the code
Nothing major here. Added comments and put the functions is a better order. Added some defensive programming.

Each field of keywords.txt is separated by a single true tab. When you use multiple tabs it causes the field to be interpreted as empty. On Arduino IDE 1.6.5 and newer an empty KEYWORD_TOKENTYPE causes the default editor.function.style coloration to be used (as with KEYWORD2, KEYWORD3, LITERAL2). On Arduino IDE 1.6.4 and older it causes the keyword to not be recognized for any special coloration.

* WAIT_TIME=50 to allow interrupts without breaking matrix output.
WAIT_TIME set to 5 was too short and FastLED aborted frames too early
and restarted them incorrectly.
(as explained by Daniel Garcia in
https://plus.google.com/communities/109127054924227823508 )
Tested on ESP8266 with 768 LED matrix in both serialized output
and 3x 256 output.
* Update clockless_block_esp8266.h
* Update clockless_esp8266.h

- Angle brackets for external includes
- Space after #include directive
|
|
Use relative paths for internal includes
|
|
This change allows the library to be used outside of the standard libraries folders. An example of when this is useful is bundling the library with a sketch so that it can be distributed as a self-contained package.

* Fix compilation error: 'NULL' was not declared in this scope
* Always typedef RoReg and RwReg for the AVR platform
* Include stdlib.h if abs() is not available
This is required as Arduino.h #define's its own abs() makro. Outside of Arduino environments stdlib is required.

./Arduino.h:#include <string.h>
* Include math.h for pow()
math.h is normally included by Arduino.h but required for a makefile build
$ grep math.h . -r
./Arduino.h:#include <math.h>
