Record+play fast 1bit sound on a PIC!
BTc “Binary Time constant” algorithm. A system to record and/or play sound in a bitstream format using just one digital output pin. This is a sound playback system for a PIC or any other microcontroller. It uses a clever encoding system to mathematically model the actual performance of the RC filter when the signal is

SD/SDHC CARD SOUND RECORDER
Updated on 30.6.2015 The PIC16F876A’s ADC digitizes the sound and store it in the SD or SDHC card. The firmware works for SD or SDHC cards only, for old SD (before 2009) use ver1 firmware. Do not use SDXC cards with this project because some of them work on 1.8V drive. The code detects whether

USB Audio Streamer A Microchip PIC based USB sound card
INTRODUCTION The idea for creating a USB sound card based on a PIC came from discussions of other people creating one on the Microchip USB forum. The hardware of the card is based on all Microchip products. The software uses a modified version of the Microchip USB framework which is interrupt driven instead of the
