This is not quite correct. This sketch is a hack that would work but the TTP229 is a true i2c device. See the following use case that deploys the wire library:
This is an easy add to the uBITx for somebody wanting a keypad ... but why not use a Nextion display with KD8CEC firmware? It already has firmware built to provide touchpad frequency entry in the UI!
It is a bit the same as building an analogue S-meter when KD8CEC firmware and Nextion already feature a classy digital S-meter that can be calibrated easily...
There are always different ways of doing things, but some ways are easier than others!
