# 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.

Install ImageMagick from source on Ubuntu 14.04

Note

These notes were for a job I am no longer at and are very dated. Please go to the imagemagick website for updated instructions.

The version of ImageMagick that is installed when you run apt-get install imagemagick on Ubuntu 14.04 is older than I would like.

$ convert --version
