Complex Projects
|
||
================
|
||
|
||
In past chapters of the tutorial series you’ve used bare minimum of nodes to
|
||
build simple projects. But what if you need to create something more complex?
|
||
|
||
The principle of programming will stay the same although you would create
|
||
more patches and use more nodes.
|
||
|
||
Search for nodes
|
||
----------------
|
||
|
||
Before implementing your own nodes check if there is a ready to use node
|
||
that will solve your problem. Visit [library index](/libs/) to browse for
|
||
existing nodes.
|
||
|
||
Interfacing with hardware
|
||
-------------------------
|
||
|
||
If you want to use a sensor or an electronic module that you haven’t find
|
||
support for it’s quite possible that all you need for it is few standard
|
||
nodes like `analog-input` or `digital-output`.
|
||
|
||
Refer to the item documentation to understand how you can talk with the
|
||
hardware.
|
||
|
||
Write a native wrapper
|
||
----------------------
|
||
|
||
You can implement a new node not only with XOD, but with C++ as well.
|
||
In this case you can even wrap an existing native library to make it
|
||
available in XOD.
|
||
|
||
See implementation of `analog-input`, `digital-output`, `text-lcd-16x2`
|
||
as an example of how to do this.
|
||
|
||
Tell us what you need
|
||
---------------------
|
||
|
||
XOD ecosystem is poor since the project is very-very young. If you need
|
||
a node for something, [ask for it on our forum](//forum.xod.io). That
|
||
would help us to better prioritize our work.
|
||
|
||
Dive into details
|
||
-----------------
|
||
|
||
Read [User’s guide](/docs/#users-guide) to understand XOD better.
