I am totally new to XOD. I was wondering how hard it would be to extend the text-lcd-16x2-i2c Node to have 4 lines of text? I have a display that uses the same PCF8574 as the 2 line display. ---

There are several examples in libraries, including gweimer/lcd-i2c-init to use variadic for number of lines. ---

Hey thanks for the help for the newbie (me). This looks like it will work well. ---

The next release (0.31.0) will include the nodes for 20×4 displays out of the box, in the new upcoming `xod-dev/text-lcd` library. Until that, there are other options, like @gweimer said. ---

Hi chuber. I had a similar need awhile back and had to modify the code for the 4x20 display here is the code from the 2x16. It works fine for both LCD screens. The issue I have is I can’t figure out how to save it as a different node. I am not a good coder but thanks to these people I can enjoy tinkering again. Then add the input terminals ![image](https://canada1.discourse-cdn.com/flex027/uploads/xod/original/2X/3/30f2b414193949168eae5a9c386b5a52948c79ce.png) ---

> [@g-p](#): > > The issue I have is I can’t figure out how to save it as a different node Hi, to clone a node, and then modify it follow these steps. 1- Open the node, select all and copy. 2- Create a new node, paste the copied. 3- Save as “Multifile XOD packet” … example: `my-lib-mod` in desktop. 4- In the library there must be a file “`project.xod`” (green icon) and node folders with “patch.xod” and “patch.cpp if applicable”. 5- You can move another node folder to my-lib-xod, but there only has to be one `project.xod` file 6- You can open the `project.xod` file, edit, add other nodes and save. 7- Go to `xod/ __lib__ / "user-name" /` copy the library from the desktop (you can not always edit the library from here, without a conflict, it is better on the desktop and move or copy here). 8- To avoid losses, you can publish the library, leave it visible or hide it from the browser.
