Any one have a working FACES calculator example?

[rickkalman]

I'm having a very hard time locating a working FACES calculator code example. The one officially provided does not compile. I can get FACES keyboard to work, but not calculator. Hoping someone can steer me in the right direction.

Thanks

I have a program for those three FACES keyboard frome the FACES Kit document.

After downloading this code, the screen on M5Core displays the corresponding value or letter once you pressed a key.

Thank you. Yes I have this one; the FACES keyboard I am able to get to working with this code. I have however not been able to found any code examples for the FACES calculator face that will compile without error for Arduino IDE. Anyone??
