# The peripheral clock is 80MHz or 12.5 nanoseconds per clock. | |
# The smallest precision of timing requried for neopixels is | |
# 0.35us, but I've decided to go with 0.05 microseconds or | |
# 50 nanoseconds. 50 nanoseconds = 12.5 * 4 clocks. | |
# By dividing the 80MHz clock by 4 we get a clock every 50 nanoseconds. |
