<![CDATA[I2C_Keyboard_Interrupt sample is not working.]]>I have tried the example provided by the M5Stack namely "I2C_Keyboard_Interrupt.ino" and it does not work. I tried the non-interrupt version "I2C_Keyboard.ino" and it works well. The hardware I use is FACES core and Game Boy Keyboard.

Does any other member also experience this issue?

According to several forum, Wire library require interrupt itself while any further interrupt is disabled during ISR call , so this example cannot work .
Only way to make working should be moving outside wire.read() function inside a proper function registered on Wire.onReceive call ( that i'm pretty sure get called from a proper interrupt ).
will make some test

Hopefully, you will find the solution. Honestly, I have no time to dig further. Good luck.

Same issue for me, tried to debug in some way, it seem at same point M5Stack ignore any interrupt from keyboard. Same behaviour on all faces

I think without using an interrupt we have to live with a blocking code and it would be inefficient code.
