Adding End of Line handling and support for 20x4 displays #43
Conversation
I was using this code with a RPi and the MCP230xx without the plate and found a need to update it with support for 20x4 (or any size that runs the HD44780 really) This also helps with some of the odd carriage return things. with more than 2 lines. See my test script for demos

FYI, this was written in such a way that it won't affect any current scripts using this library. You would have to add a new var to the "message" function call to get the new features End of Line features. The 4 line support is automatic. |

Would it be possible to just spin off this library to a new one that just supports different size displays when used with the MCP230xx chips. Then we can remove the button stuff. and then also make the RGB things optional? Not sure how to make a whole new sub folder request. (new to github) |

There was a problem hiding this comment.
This defaults the begin statement to the 16x2 display

Thanks for submitting the pull and apologies it wasn't reviewed sooner. I made a few small tweaks to simplify the logic and add some constants for the message truncation parameter values. Just merged in the change, thanks again for submitting! |
