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_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

|
version.

NOTE: This task isn't enabled by default, see the commented out line in user_init.
