The step that sets the iomux register can't be automatically
updated from the 'gpio' constant variable, so you need to change
- the line that sets IOMUX_GPIO14 if you change 'gpio'.
+ the line that sets IOMUX_GPIO2 if you change 'gpio'.
There is no significant performance benefit to this way over the
blinkenTask version, so it's probably better to use the blinkenTask
