Complex Projects
|
||
================
|
||
|
||
In the tutorial's past chapters, you’ve used a bare minimum of nodes to build
|
||
simple projects. But what if you need to create something more complex?
|
||
|
||
The programming principles stay the same even if you 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 found
|
||
support for, it’s quite possible that all you need is a few standard nodes
|
||
like `analog-input` or `digital-output`.
|
||
|
||
Refer to the item's documentation to understand how you can talk with the
|
||
hardware.
|
||
|
||
Write a native wrapper
|
||
----------------------
|
||
|
||
You can implement new nodes not only in XOD, but also with C++.
|
||
You can even wrap an existing native library to make it available in XOD.
|
||
|
||
See the implementation of `analog-input`, `digital-output`, and `text-lcd-16x2`
|
||
for examples of how to do this.
|
||
|
||
Tell us what you need
|
||
---------------------
|
||
|
||
The XOD ecosystem is barebones since the project is very-very young. If you
|
||
need a node for something, [ask for it on our forum](//forum.xod.io). That will
|
||
help us better prioritize our work.
|
||
|
||
Dive into details
|
||
-----------------
|
||
|
||
Read the [User’s guide](/docs/#users-guide) to understand XOD better.
