Thanks for the detailed explanations. Seems like since I have the row and column scanning routines already, the remaining thing to do is set up the interrupt. Will this work like a switch? So if I connect INTA to say B13 on espruino, do I simply setwatch B13 and anytime button is pressed on the matrix an event will fire? Or do I need to set up something between the expander GPIO and the INTA?
Much appreciated!
