heart of the FastLED library is the fast pin accesss. This is a templated class that provides 1-2 cycle pin access, bypassing digital write and other such things. As such, this will usually be the first bit of the library that you will want to port when moving to a new platform. Once you have FastPIN up and running then you can do some basic work like testing toggles or running bit-bang'd SPI output.</p> +<p>There's two low level <a class="el" href="class_fast_pin.html" title="The simplest level of Pin class. ">FastPin</a> classes. There's the base FastPIN template class, and then there is <a class="el" href="class_fast_pin_b_b.html">FastPinBB</a> which is for bit-banded access on those MCUs that support bitbanding. Note that the bitband class is optional and primarily useful in the implementation of other functionality internal to the platform. This file is also where you would do the pin to port/bit mapping defines.</p> +<p>Explaining how the macros work and should be used is currently beyond the scope of this document.</p> +<p>== Porting <a class="el" href="fastspi_8h_source.html">fastspi.h</a> ==</p> +<p>This is where you define the low level interface to the hardware SPI system (including a writePixels method that does a bunch of housekeeping for writing led data). Use the <a class="el" href="fastspi__nop_8h_source.html">fastspi_nop.h</a> file as a reference for the methods that need to be implemented. There are ofteh other useful methods that can help with the internals of the SPI code, I recommend taking a look at how the various platforms implement their SPI classes.</p> +<p>== Porting clockless.h ==</p> +<p>This is where you define the code for the clockless controllers. Across ARM platforms this will usually be fairly similar - though different arm platforms will have different clock sources that you can/should use. </p> +</div></div><!-- contents --> +<!-- start
