BOOSTXL-AUDIO

Audio Signal Processing BoosterPack Plug-In Module

BOOSTXL-AUDIO

Overview

When plugged into a LaunchPad™ Development Kit, the BOOSTXL-AUDIO Audio BoosterPack™ Plug-in Module can capture audio input from a microphone and output audio through an on-board speaker. Headphone input and output is also supported. This audio input/output stream lets developers experiment with the digital signal processing (DSP) and filtering capabilities of the microcontroller (MCU) found on the attached LaunchPad Development Kit.

There are various options – selectable by a jumper on the BoosterPack – for connecting the speaker to the Launchpad’s MCU: (1) output audio data over SPI to the SPI DAC provided on the Audio BoosterPack; (2) directly connecting to the DAC on the LaunchPad’s MCU (if available); or (3) use the LaunchPad's PWM output together with a basic R/C filter on the BoosterPack, to create a simple, low-cost analog audio signal.

Get started

Step 1: Buy the BOOSTXL-AUDIO BoosterPack and the MSP-EXP430FR5994 LaunchPad
Step 2: Select the software examples and import them to CCS Cloud IDE
Step 3: Complete the demos
Step 4: Take the Advanced Signal Processing trainings

  • High quality audio playback with onboard 14-bit DAC (can be bypassed if target MCU has an integrated DAC)
  • Automatic switching from onboard speakers and microphone to a headset with microphone
  • Onboard microphone supports sampling rates of up to 20kHz
