// [[[Begin of the Neopixel NRF52 EasyDMA implementation
// by the Hackerspace San Salvador]]]
// This technique uses the PWM peripheral on the NRF52. The PWM uses the
// EasyDMA feature included on the chip. This technique loads the duty
// cycle configuration for each cycle when the PWM is enabled. For this
// to work we need to store a 16 bit configuration for each bit of the
// RGB(W) values in the pixel buffer.
// Comparator values for the PWM were hand picked and are guaranteed to
// be 100% organic to preserve freshness and high accuracy. Current
// parameters are:
// * PWM Clock: 16Mhz
// * Minimum step time: 62.5ns
// * Time for zero in high (T0H): 0.31ms
// * Time for one in high (T1H): 0.75ms
// * Cycle time: 1.25us
// * Frequency: 800Khz
// For 400Khz we just double the calculated times.
// ---------- BEGIN Constants for the EasyDMA implementation -----------
// The PWM starts the duty cycle in LOW. To start with HIGH we
// need to set the 15th bit on each register.
// WS2812 (rev A) timing is 0.35 and 0.7us
//#define MAGIC_T0H 5UL | (0x8000) // 0.3125us
//#define MAGIC_T1H 12UL | (0x8000) // 0.75us
// WS2812B (rev B) timing is 0.4 and 0.8 us
#define MAGIC_T0H 6UL | (0x8000) // 0.375us
#define MAGIC_T1H 13UL | (0x8000) // 0.8125us
#define CTOPVAL 20UL // 1.25us
// ---------- END Constants for the EasyDMA implementation -------------
//
// If there is no device available an alternative cycle-counter
// implementation is tried.
// The nRF52840 runs with a fixed clock of 64Mhz. The alternative
// implementation is the same as the one used for the Teensy 3.0/1/2 but
// with the Nordic SDK HAL & registers syntax.
// The number of cycles was hand picked and is guaranteed to be 100%
// organic to preserve freshness and high accuracy.
