How To Use PIC Microcontroller For Voice Input And Output- (Part 23/25)

Microcontrollers are purely digital devices which work on logic0 and logic1 voltages; still they are widely used for analog signal processing. There are specialized signal processors chips available which are custom made for particular applications; however a general purpose microcontroller is more than enough for small kind of signal processing applications like audio signal input and output. The microcont ...

DAC MCP4921 Interfacing with PIC Microcontroller PIC16F877A

Digital and Analog is an integral part of Electronics. Most of the devices have both ADC as well as DAC and they are used when there is a need of converting signals either from analog to digital or digital to analog. Also the real world signals like sound and light are analog in the nature, so whenever these real world signals have to be used, the digital signals have to be converted to analog, for example ...

Wave player using PIC18F4550 microcontroller

Making an audio player (.wav files) using PIC microcontroller is not complicated especially when the MCU has a PWM module. This topic shows how to build an audio player using PIC18F4550 microcontroller where the the file is stored in an SD card with FAT16 or FAT32 file system. In this project I used a wave file with sample rate of 16000 Hz and 2 channels (stereo). The file I used originally it was an MP3 fi ...
