Post by thread:serial memory (24LC256) - how to "fill"

G'Day, Can some one please tell me how to "fill" a memory chip? I am working my way through some of the audio playback notes on http://www.piclist.com in an effort to overcome the failings of the APR voice chip I have been using. I've got my messages saved on my PC as .wav files, and can play with editing the bit rate etc to suit my PIC coding, but I'm wondering how to get the data into the memory chip for the PIC to play them back. I cannot pretend to fully understand how all the speech works, but I understand it at a "block level" and need to start drilling down so I can implement it. What I want to accomplish... a series of short messages (words and sounds) the PIC (I have F84, and F628) will play the messages based on user input, and program flow. I see similar things on the website owned by Roman Black, so it must be being accomplished somehow.... Many thanks in advance, Des Bromilow Brisbane OZ -- http://www.piclist.com hint: The PICList is archived three different ways. See http://www.piclist.com/#archives for details.

Theres a similar project here that uses a 24LC256 http://www.bubblesoftonline.com/demo/WavePlay.zip Des Bromilow wrote: {Quote hidden}> > G'Day, > > Can some one please tell me how to "fill" a memory chip? > > I am working my way through some of the audio playback notes on http://www.piclist.com in an effort to overcome the failings of the APR voice chip I have been using. > I've got my messages saved on my PC as .wav files, and can play with editing the bit rate etc to suit my PIC coding, but I'm wondering how to get the data into the memory chip for the PIC to play them back. > > I cannot pretend to fully understand how all the speech works, but I understand it at a "block level" and need to start drilling down so I can implement it. > > What I want to accomplish... > a series of short messages (words and sounds) > the PIC (I have F84, and F628) will play the messages based on user input, and program flow. > > I see similar things on the website owned by Roman Black, so it must be being accomplished somehow.... > > Many thanks in advance, > Des Bromilow > Brisbane > OZ > > -- > http://www.piclist.com hint: The PICList is archived three different > ways.

Thanks Tony, I'll have to wait until I'm home before I can install the app and read it. Do you know if it covers downloading the .wav into the serial memory chip? (I want all the chips to sound the same) I'm absolutley loving learning about the chips etc, but the learning curve is a little steep sometimes (compared to the time I have spare, and the size of my ambitions!!)

The draw back maybe that it creates a byte wide data stream, not a single bit stream for the audio. -- Best regards Tony mICros http://www.bubblesoftonline.com .....salesKILLspam.....bubblesoftonline.com -- http://www.piclist.com hint: The PICList is archived three different ways.

(I want all the chips to sound the same) You can use my Picsound BTc encoder to convert the windows wave files to the 1bit or 1.5bit formats.

Just dive in Des, sometimes you sink but it doesn't matter. ;o) -Roman -- http://www.piclist.com#nomail Going offline?
