Play AUDIO Using PIC24............? | Microchip
https://www.microchip.com/forums/m551538.aspx
I currently play uncompressed PCM wav files using a PIC24F. The wav files are stored on an SD card. I use PWM to playback the wav files. I simply send a PWM signal through a low pass filter then send it through a volume controller and amplifier. It is pretty simple you just need to read the wav settings out of the file header, set up your PWM ...
Singular Engineer » dsPIC/PIC24 PWM (using XC16 and MPLAB X)
https://singularengineer.com/dspicpic24-pwm-using-xc16-and-mplab-x/
dsPIC/PIC24 PWM (using XC16 and MPLAB X) Pulse Width Modulation (PWM) in dsPIC/PIC24 works from output compare section (OC). OC is simply a comparator. One input is from a timer and another from OC register where we set the value. The timer is used to set the frequency of the PWM and OC register for setting the duty cycle.
How to Generate Sound using PWM with PIC …

This feature of the PWM wave is making use in so many digital systems like DC motor control, audio devices, simple decoration light controls etc. The PIC18F4550 has an inbuilt PWM module which can generate continuous PWM waves. This project explores the PWM module of the PIC18F4550 and tries generating a sine wave with frequency in the audible ...

Re: Pic24 pwm. Without a main loop the PC will just increase until it overflows and starts over at 0x0000, this is the best scenario assuming that an erased flash will contain what will be executed as nops, worst case, it will be random junk …

The audio is generated using PWM technique, basically the PIC18F4550 has two PWM modules and their output are RC2 and RC1 for PWM1 and PWM2 respectively. An audio amplifier is needed to amplify the audio. In my circuit I used PC speaker as an amplifier. If the audio is stereo (2 channels) connect the same amplification circuit and use PWM2 ...
Audio Application based on FreeRTOS Operating System
https://upcommons.upc.edu/bitstream/handle/2117/101745/TFG_Pau_Mendieta.pdf
to a Microchip PIC24 microcontroller. The original Real Time Operating System has also been migrated from OSA RTOS to FreeRTOS. The RTOS modification will allow future upgrades without the need to change the RTOS. The Quartet software is an audio synthesizer which uses a low-pass filtered PWM output to create a mono audio signal.
