// function cannot be avoided, or when extremely high performance
// is not needed.
//
// NOTE 4: Why is this 'only' an "approximation"?
// Not all RGB colors have HSV equivalents! For example, there
// is no HSV value that will ever convert to RGB(255,255,0) using
// the code provided in this library. So if you try to
// convert RGB(255,255,0) 'back' to HSV, you'll necessarily get
// only an approximation. Emphasis has been placed on getting
// the 'hue' as close as usefully possible, but even that's a bit
// of a challenge. The 8-bit HSV and 8-bit RGB color spaces
// are not a "bijection".
//
// Nevertheless, this function does a pretty good job, particularly
// at recovering the 'hue' from fully saturated RGB colors that
// originally came from HSV rainbow colors. So if you start
// with CHSV(hue_in,255,255), and convert that to RGB, and then
// convert it back to HSV using this function, the resulting output
// hue will either exactly the same, or very close (+/-1).
// The more desaturated the original RGB color is, the rougher the
// approximation, and the less accurate the results.

/* nrf_pwm solution
//
// When the nRF52 softdevice (e.g., BLE) is enabled, the CPU can be pre-empted
// at any time for radio interrupts. These interrupts cannot be disabled.
// The problem is, even simple BLE advertising interrupts may take **`348μs`**
// (per softdevice 1.40, see http://infocenter.nordicsemi.com/pdf/S140_SDS_v1.3.pdf)
//
// The nRF52 chips have a decent Easy-DMA-enabled PWM peripheral.
//
// The major downside:
// [] The PWM peripheral has a fixed input buffer size at 16 bits per clock cycle.
// (each clockless protocol bit == 2 bytes)
//
// The major upsides include:
// [] Fully asynchronous, freeing CPU for other tasks
// [] Softdevice interrupts do not affect PWM clocked output (reliable clocking)
//
// The initial solution generally does the following for showPixels():
// [] wait for a sequence buffer to become available
// [] prepare the entire LED string's sequence (see `prepareSequenceBuffers()`)
// [] ensures minimum wait time from prior sequence's end
//
// Options after initial solution working:
// []
// TODO: Double-buffers, so one can be doing DMA while the second
// buffer is being prepared.
// TODO: Pool of buffers, so can keep N-1 active in DMA, while
// preparing data in the final buffer?
// Write another class similar to PWM_Arbiter, only for
// tracking use of sequence buffers?
// TODO: Use volatile variable to track buffers that the
// prior DMA operation is finished with, so can fill
// in those buffers with newly-prepared data...
// apis to send the pre-generated buffer. This would be essentially asynchronous,
// and result in efficient run time if the pixels are either (a) static, or
// (b) cycle through a limited number of options whose converted results can
// be cached and re-used. While simple, this method takes lots of extra RAM...
// 16 bits for every full clock (high/low) cycle.
//
// Clockless chips typically send 24 bits (3x 8-bit) per pixel.
// One odd clockless chip sends 36 bits (3x 12-bit) per pixel.
// Each bit requires a 16-bit sequence entry for the PWM peripheral.
// This gives approximately:
// 24 bpp 36 bpp
// ==========================================
// 1 pixel 48 bytes 72 bytes
// 32 pixels 1,536 bytes 2,304 bytes
// 64 pixels 3,072 bytes 4,608 bytes
//
//
// UPDATE: this is the method I'm choosing, to get _SOMETHING_
// clockless working... 3k RAM for 64 pixels is acceptable
// for a first release, as it allows re-use of FASTLED
// color correction, dithering, etc. ....

#define __FASTPIN_ARM_NRF52_H
/*
//
// Background:
// ===========
// the nRF52 has more than 32 ports, and thus must support
// two distinct GPIO port registers.
//
// For the nRF52 series, the structure to control the port is
// `NRF_GPIO_Type`, with separate addresses mapped for set, clear, etc.
// The two ports are defined as NRF_P0 and NRF_P1.
// An example declaration for the ports is:
// #define NRF_P0_BASE 0x50000000UL
// #define NRF_P1_BASE 0x50000300UL
// #define NRF_P0 ((NRF_GPIO_Type*)NRF_P0_BASE)
// #define NRF_P1 ((NRF_GPIO_Type*)NRF_P1_BASE)
//
// Therefore, ideally, the _FL_DEFPIN() macro would simply
// conditionally pass either NRF_P0 or NRF_P1 to the underlying
// FastPin<> template class class.
//
// The "pin" provided to the FastLED<> template (and which
// the _FL_DEFPIN() macro specializes for valid pins) is NOT
// the microcontroller port.pin, but the Arduino digital pin.
// Some boards have an identity mapping (e.g., nRF52832 Feather)
// but most do not. Therefore, the _FL_DEFPIN() macro
// must translate the Arduino pin to the mcu port.pin.
//
//
// Difficulties:
// =============
// The goal is to avoid any such lookups, using compile-time
// optimized functions for speed, in line with FastLED's
// overall design goals. This means constexpr, compile-time
// and aggressive inlining of functions....
//
// Right away, this precludes the use of g_ADigitalPinMap,
// which is not constexpr, and thus not available for
// preprocessor/compile-time optimizations. Therefore,
// we have to specialize FastPin<uint8_t PIN>, given a
// compile-time value for PIN, into at least a PORT and
// a BITMASK for the port.
//
// Arduino compiles using C++11 for at least Feather nRF52840 Express.
// C++11 is very restrictive about template parameters.
// Template parameters can only be:
// 1. a type (as most people expect)
// 2. a template
// 3. a constexpr native integer type
//
// Therefore, attempts to use `NRF_GPIO_Type *` as a
// template parameter will fail....
//
// Solution:
// =========
// The solution chosen is to define a unique structure for each port,
// whose SOLE purpose is to have a static inline function that
// returns the `NRF_GPIO_Type *` that is needed.
//
// Thus, while it's illegal to pass `NRF_P0` as a template
// parameter, it's perfectly legal to pass `__generated_struct_NRF_P0`,
// and have the template call a well-known `static inline` function
// that returns `NRF_P0` ... which is itself a compile-time constant.
//
// Note that additional magic can be applied that will automatically
// generate the structures. If you want to add that to this platform,
// check out the KL26 platform files for a starting point.
//
