NuttX provides a POSIX like API for application development. In this article we will see, how to develop simple NuttX applications. This is the third article in the NuttX series, for the previous articles please see:

This article is a follow-up of the NuttX, Getting Started article. In the previous article we demonstrated NuttX, using the NuttShell application. In this article we will see how to build NuttX and NuttX applications from source.
