Hi, so I like the concept of xod, and I like the idea that this will let me iterate quickly. However, I don’t yet understand how I can take something like the w5500 libraries and create a custom node. I’ve already written some of the code I want in normal C++, but am completely confused how to translate this to a patch based system. I guess more specifically… Is there a way to Auto generate node types from class architecture in the normal C++ libraries? If I have to manually write it myself… Not great, but doable. ---

update: I found the w5500 node. and have figured out that auto generation can’t be a thing… yet. Looks like I’ll be creating a bunch of new nodes for myself then. Is there somewhere I can see a tutorial on how to use Github, or some other thing to share my sensor nodes? Never going to become popular if I keep my code to myself… 😉 ---

You can use File \> Publish Library to make a project available for everyone to use. Generally, libraries do not have a main node, but just a collection of nodes to re-use. One or more test nodes can also be included to demonstrate how the other nodes can be used. ---

> [@mlconti](#): > > Any Help on why I am getting this error - just installed XOD - love the concept… 1. You should start your own thread instead of adding new topics to old threads. 2. The reason compile failed is “ESP8266WiFi.h: No such file or directory”. The reason XOD could not find that is not so obvious. You can search for that filename under C:\Users\Michael C. If it exists, a likely problem is that your username has a space in it & that is breaking XOD’s search for it. ---

Can you tell why it is looking for an ESP… related file when i am using a MEGA? I will see if that exist but I am not sure what it has to do with a device that is not present in the project. ---

Did you select MEGA device when doing download? If so, do you have any nodes in your patch trying to use the wifi?
