Overview
Description
The Hear-it! Solution Kit demonstrates the application of the DSP signal filtering capabilities of the RX231 MCU to an audio source, which is then made available from the on-board headphone or speaker connections. A total of 4 pre-set filters are available, applicable to either channel, and the chosen characteristic is displayed on the Pmod™ display. A second configuration of the sample code demonstrates the streaming of audio from a mass-storage device connected to the USB host interface, where a simple GUI and input controls allow the selection of the .wav file to be played. The board includes an embedded E2 Lite programmer/debugger and would be an ideal platform to be used as a basis for further development.
An excellent choice for your next audio project using the DSP capabilities of the RX231 MCU:
- Sample input from the audio jack via the codec and Serial Sound Interface (SSI)
- Stream audio from USB mass storage
- Headphone and/or speaker output from codec via SSI
- Using the DSP capabilities of the RX231 for signal filtering
Part number: Y-HEAR-IT-RX231
