Create, Build and Run Project
1. Refer to the MPLAB X IDE User's Guide or online help
for instructions to install language tools, create or
open a project, and congure project properties.
2. Check that the conguration bits in your code match
the Recommended Settings below.
3. To execute your code in Debug mode, perform a
debug run. To execute your code in Non-Debug
(release) mode, perform a run. To hold a device in
Reset after programming, use the Hold in Reset icon
in the toolbar.
