Hello friends, I hope you all are doing great. Today, I am going to share the new TTP229 Touch Keypad Library for Proteus V1.0 . The red TTP229 16-key capacitive touch keypad is the easiest way to give an Arduino project a modern, button-free front panel: sixteen round pads under a thin cover, no moving parts, nothing to wear out. It talks to the Arduino over two wires, SCL and SDO, and for a hobby board it hides a surprising number of traps: it comes with only 8 of its 16 keys switched on, it reports one key at a time unless you bridge two pads, and its serial interface is not I2C at all. Behind the parts sits our own model , written from the TTP229-BSF datasheet. You click the pads on the board while the simulation runs, and the chip answers the way the real one does: it calibrates at po ...
