    I need to use 3 of these devices, 1 for a 4x3 keypad and 2 others for 14 buttons. I understand the addressing of the chips but in the arduino example I dont see where I access the 0x5a to change it to 0x5b, etc. also now I have 3 interrupts to handle and of course I’m using a 328p which I believe only has 2 interrupt pins? any ideas on that? I was thinking about putting the 2 into an OR gate and just reading both chips when the irq is triggered. thanks.

No public wish lists :(
