+// [[[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.
