That is doubtful, but a "C" library is likely to be near compatible for PICs, from that you can dissasemble and harvest what you need, maybe. Did you request they send it to you ?
You are going to want to see what is in these 2 files:
#include <Wire.h>
#include <LiquidCrystal_I2C.h>
So as to understand what information gets sent to the MCU on the "shield" or Backpack. Essentially all data in an MCU is just numbers, so if you can get that data then you can see what it is doing. I bought some I2C / SPI displays a while back and setup a pic to send numerical data, just counting upward and watched and counted to see what the resulting display was.
