LCD - java.lang.NullPointerException

Post by cmpts_cmp » 28 Aug 2019 11:07

Hi all,


Complete newbie but I'm using the Z-Uno connected to my Windows 10 PC.

I can program the ZUNO no issue, but when I use the LiquidCrystal library (#include <LiquidCrystal.h>) I get the following error when compiling, not even uploaded yet.

I've done the Burn Bootloader, and general "getting started" tasks, and all went well, but all seems to point to thie LCD library:

--- USING a list of libraries from:

      C:\Users\<USER>\AppData\Local\Arduino15\packages\Z-Uno\hardware\zw8051\2.1.5\libraries

      C:\Users\<USER>\Documents\Arduino\libraries

I fear this library might require quite some adoption.

Thanks. I think you're right. I'll see if it's possible to "swap" what's used in the sketch and use the ZUNO specific library.
