What i need to save a sound in the PIC microcontroller,and how?


I want to save my sound like "right" word.

thanks
 

play sounds with pic microcontrollers and sd card

Hi

You will need a PIC with A/D, lot of memory (flash) and D/A converter (you can also use PWM)

You will also need to use some compress and decompress algorithm like A-low or u-low etc in order to save space on the flash memory

there are lots of program to save analog audio over flash memory on a microcontroller -serach microchip site for demo

You will also need to use the 16 bir PIC like the PIC24 or PIC30 family - for better performance

All the best

store for all sound to a microcontroller

thank u Bobi

I Asked if can u help me,to programming EEPROM (Read,write), with the PIC microcontroller .
 

pic30 sd card

Hi!
You need a PIC microcontroller with an ADC and a little bit of analog circuitry (Mic+amplifier) to sample and digitize the sound. For storing the sound i would recommend you to use the SD card instead of an EEPROM. The SD card is very fast and has a lot of capacity at a comparatively low cost. e.g in Pakistan the cost for a 1GB card is only Rs.350. At a sampling rate of 4KHz a 1GB card will store up to 69 hours of sound. Isn't it great.
In order to playback the sound you will need a D/A converter (PWM can also be used) and a simple amplifier to regenerate the sound.
If this does not solve your problem feel free to ask.
Regards.
 

sound microcontroller

thank u waseem;

Can u draw to me the circuite diagram?

My project is a process of converting a remote control for a machine (car,..etc) to sound commands.

I have PIC16f877A, amplifier,SD card, and I can get to any other components.

Thanks
 

pic microcontroller sd card sound

Hi!
Yes, I will try my best. How much time you have got for the project? I will try to design the schematic. Initially you can start simulating your program in proteus software.
Are you from Pakistan?.
Regards.
 

sound from pic

thanks

Ok, i have 1 week to do this project.

and i am jordanian .
 

microcontroller sound store and compare pic

Hi

I am Asking How can I controlling the ADC's time in PIC16F877A?
 

how to save audio to pic24

Assalam-o-alikum!
U mean how to control the conversions per secound i.e the sampling frequency?
Allah hafiz.
 

sound interface with pic microcontroller

There is a complete sample in the Proteus Samples directory (with a PIC24) using ADPCM encoding and a sallon-key filter for output. Could be useful to get you going...
