Hello,

Just for your information, it can work on STM32F103ZE on the STM3210E-Eval board. I have now realtime read mp3 from SD card and decode to PCM data and used the codec to play the music. I think this, in my integration now uses arround 90-95% of the CPU time. I think the most time is used in the irq on SPI to the codec. Kasper

Kasper,

Check the forum for Ogg Vorbis http://www.st.com/mcu/forums-cat-7647-23.html And the links to LPC2148 based projects http://www.circuitcellar.com/library/print/0906/Szymanski194/index.htm http://www.standardics.nxp.com/support/documents/microcontrollers/pdf/an10583.pdf Good luck Jan

Hello all,

While using Helix MP3 Library, I am receving errors like invalid frame. The frame acrording to me seem to be ok, with all the frames having exactly same frame headers. Any help would be highly appreciated. Thanks Regards, Ankita
