No, I didn’t do that as I didn’t need them or really want them. Depending on the hardware, it shouldn’t be difficult but it could depend on what’s hooked up where. The i2c controller I used as part of the LCD I believe has a couple extra pins you can trigger things on but I didn’t want to spend the effort to wire it all up and further reverse engineer the software to make them work.
The LCD I used was from Amazon: Link
But DONT just hook it up! it does require some modifications for a i2c 3v3 vs LCD powered at 5v.
