2. Introduction
The Hear-it! Solution Kit is designed to demonstrate the capability of the Renesas RX231 microcontroller in low
cost audio processing applications. Digital filtering can be applied to an audio input source (3.5mm line-in or
optionally a Mic input) and the result output to 3.5mm speaker or line-out connection. A demonstration of audio
playback from a USB mass storage device connected to the USB Host connector is also provided. The single-
board PCB also incorporates an integrated E2-Lite debugger/programmer, a PMOD
TM
interface for connection
of a display (supplied) and provides a flexible hardware and software platform to be used as a basis for further
developments.
This user manual has been written to help the user understand the sample code provided with the Hear-it! Kit.
It is intended to be read by those using the Hear-it! as a guide or starting point for their own applications.
Renesas Firmware Integration Technology (FIT) is used to initialise and drive hardware modules that are needed
for this sample. Using FIT ensures the portability of this sample between different microcontrollers in the RX
family.
