MSP430FR5994: BOOSTXL-AUDIO Sample Project

Annie Rizvi

Part Number: MSP430FR5994
Other Parts Discussed in Thread: BOOSTXL-AUDIO,

I am attempting to use the sample project, BOOSTXL-AUDIO_RecordPlayback_MSP430FR5994, provided in Code Composer Studio to create a program that can create a harmony in real time using the MSP430 and the BOOSTXL-AUDIO pack. However, when I attempt to run the initial project without any changes the code does not work as expected.

I press S1 as stated in the instructions for recording for 3 seconds and the red LED lights up. When I press S2 the green LED lights up indicating playback but I only hear static instead of the audio I just generated.

I’d appreciate help on what I’m doing wrong. The project code remains untouched and both the MSP430 and BOOSTXL-AUDIO pack were bought brand new.

Hi Annie,

Let me dig into this for you.

Hi Annie,

I apologize for the delay. I'm tracking down a BOOSTXL-AUDIO PCB and unfortunately it is taking some time.

Hi Annie - I finally received a BOOSTXL-AUDIO boosterpack. I will look into your issue first thing in the morning.

Hi John,

Yes, I have same problem as reported by Annie. This demo HW/SW has been out for several years now so I'm perplexed as to why it is not working. I promise to update you later in the day.

Hi Dennis, any update on the sample project and what the potential issue is? Thanks.

Hi Annie,

I'm seeing the microphone and amplifier are working during the record, but not seeing any DAC output from FR5994 during playback. I'm presently tracing through the code to see if the audio is actually being recorded or if the problem has to do with the playback. I'll know something shortly.

Hi Annie,

You need to disable the MPU settings by un-checking the box shown here. You will need to right-mouse click on the name of the project, then select Properties at the bottom of the drop-down menu. When the dialog box appears, click on CCS General and un-check the Enable Memory Protection Unit (MPU).

Thank you so much. This resolved the issue. I'm able to hear the audio that is generated from the microphone.
