Title: how can I use this MSM5205 with a PIC Post by: gianmagna on February 21, 2014, 10:55:08 22:55 I have several integrated MSM5205 ADPCM of OKY and would like to use them with the pic 18f2520 or another
Is there anyone who knows how to use this chip to play audio files. I thank anyone give me some help. http://www.datasheetarchive.com/MSM5205-datasheet.html Title: Re: how can I use this MSM5205 with a PIC Post by: Wilksey on February 22, 2014, 02:20:35 14:20 The chip accepts a 4-bit ADPCM input, and you can use this:
