Part Number: MSP430F5529
I am working on a personal project where I get an audio signal and lights up a 32x32 LED matrix. So far, I have put together code that is utilizing the ADC of my MSP430F5529 Launchpad. I am planning on sending the audio signal through a FFT and then to the LED matrix. I was wondering if anyone could point me towards some example codes that show how to use the FFT coming from the ADC, and/or code that will send the LED Matrix a signal to light up from the FFT output. I have been using Code Composer Studios
I appreciate any help or ideas.
I know you're working on the MSP430F5529 but have you considered using the MSP430FR5994? The MSP430FR5994 has a Low Energy Accelerator (LEA) that can perform functions like FFT at low power. There is also a TI reference design called Filtering and Signal Processing with Low Energy Accelerator (LEA) on MSP FRAM Microcontroller that shows how to use the module with audio and an LCD display. Let me know your thoughts.

In reply to Hayden Oeser:
There are no analog output pins. To get a copy of an input signal, use a wire.
In reply to Clemens Ladisch:
PWM or another sort of DAC would require external components to convert the digital signal back to analog.
If you have an external component anyway, better route the original signal through an analog multiplexer (e.g., SN74LV4051A/CD4051B or SN74LV4052A/CD4052B).
