The Rapid IOT Software Development Kit (SDK) is based on the MCUXpresso Software Development
Kit (MCUXpresso SDK) and builds on it by providing the firmware for interfacing with the hardware built
around the K64F and the KW41Z microcontrollers in the Rapid IOT. In this document you will find the A -
PI function calls to the various sensors, touch controller, secure authenticator, port interrupts, UI manager,
display, lights, buzzer and battery sensor. Please refer to the MCUXpresso SDK for the underlying drivers
and middleware on which the Rapid IOT SDK is based.
