PIC32MX for audio processing (using PWM output) Hello everyone, I recently purchased a Microstick II Board with the included PIC32MX250F128B and I would like to play with it. I already started to do some basics things using MPLABX and XC32 compiler under linux.

PIC32MX LED PWM Introductory project for Microstick II with PIC32MX. It does two things: control on-board LED D6 (on OC1, PIN2) brightness from 0% to 100% (and again starting from 0%) using PWM (OCMP1 peripheral) blinks external LED (on PIN3, RA1) with 200ms period - it works as primitive "watchdog" that everything is running.

So our first order of business will be to convert that 16-bit sign data into the 11-bit unsigned data our PWM channels expect. We can do it as follows: output_data = ( (input_data + 32,768) >> 5) <TL;DR> Signed 16-bit audio data is represented as a …
PIC32 Stereo Audio Player with microSD card | Hackaday.io
https://hackaday.io/project/3815-pic32-stereo-audio-player-with-microsd-card
Using the PIC32MX250F128B, I decided to make a simple audio player. I wanted to play back good quality audio from a large memory space - a microSD card. So, I made this WAV player that can play back 16-bit 44.1kHz WAV files with 12-bit stereo audio output. Of course that's not all it can play back. It is programmed for automatic period configuration so that the period is set on …

PIC32 Output Compare Overview - Developer Help
https://www.microchipdeveloper.com/32bit:oc-overview
PIC32 Output Compare Overview. The Output Compare (OC) module is one of the peripherals in the PIC32 MCUs. Its operation requires a timer and one or two compare values. Users have an option to select either a 32-bit timer or a 16-bit timer. The timer can be programmed to count at a desired frequency and count up to a desired period value.
