The CAP1188 Touch is an I²C device in the LabWired part catalog. Its catalog type is cap1188. It connects to the MCU over I²C at the default address 0x29. The catalog gives a supply range of 3–5.5 V. It has 4 pins. A registered peripheral model runs in the engine: the firmware talks to it over the real bus and gets device-accurate responses.
From the catalog: Declarative I²C kit — core/configs/devices/cap1188.yaml. Latched status bits and MAIN_CONTROL.INT behave as on silicon (a still-held pad re-asserts INT after the write-0). NOT modelled: the ALERT pad (nothing drives a pin), the noise detector, multiple-touch blocking, the guard channel, the LED drivers, recalibration and standby. Touch strength is a fixed 50%-of-full-scale threshold, not the analogue calibration loop.

Simulated device model
Built from the datasheet. Implemented from the part’s register documentation and exercised by automated tests. Nothing physical was ever placed next to it.

These catalog parts use the same default address. Two parts at one address cannot share one bus segment. A bus switch such as the TCA9548A puts them on separate segments.
