New LiquidCrystal Library question

Hey all, sorry if this is the wrong topic for this post, wasn't really sure where this fit. I'm trying to set up my arduino stuff on a new machine (mac) and am wanting to install the New LiquidCrystal library, but I can't for the life of me find the original LiquidCrystal library that comes with the IDE in order to remove/rename it as per all of the instructions and posts I've read say I need to do... The library manager tells me LiquidCrystal is installed, but there is nothing in my library folder... can anyone tell me where on a mac I can find the preinstalled libraries?


why would you want to remove that one? where did you read this? and which one do you want to put instead?

On your mac the built in libraries are hidden inside the IDE application package


you can go and see that content by navigating in the finder into your Apps and right clicking (or ctrl-click) on the app icon and select "Show Package Content".

that will open a new finder window where you can navigate to the right folder

Thanks JML, pretty much everything I've read said you need to do this to install the new liquid crystal library...

From the bitbucket site....!downloading-and-installation

I am trying to do this because it was how i got my lcd working in the sketch on my old lap top, which is with my wife right now for a week and i want to do some editing, so I'm trying to set it up on this machine the same as it was on the other :slight_smile:


OK - it's not good practice from them to have called the library exactly the same way... but yes, in that case just go to the folder, move the old one somewhere and install the new one there

I suppose you want the "almost 5 times faster" :slight_smile:

don't actually care about the speed, just I'm really really really new at this and once i can get something to work, I really don't want to tinker with it again :slight_smile:

Are you using an I2C backpack with the LCD?
If so, you could use use my lcd library as it is easier to install, and will auto detect the backpack i2c address and self configure the pin mapping for you.
It is called hd44780 and is available in the library manager and can be installed in just a few seconds.

Thanks Bill! I will check that out for sure :slight_smile:
