[incubator-nuttx-apps] branch master updated (71f5af4 -> 21e0ff1)

This is an automated email from the ASF dual-hosted git repository.

xiaoxiang pushed a change to branch master
in repository https://gitbox.apache.org/repos/asf/incubator-nuttx-apps.git.


    from 71f5af4  GPIO example application: Add support for changing pintypes
     new 128996f  timer_gpout example: use /dev/gpioN instead of /dev/gpoutN
     new 21e0ff1  timer_gpout example: rename to timer_gpio

The 2 revisions listed above as "new" are entirely new to this
repository and will be described in separate emails.  The revisions
listed as "add" were already present in the repository and have only
been added to this reference.
