Note that the vs1003 recorder needs a pre-existing file which it overwrites.

The package is still available if you guess the filename correctly. http://www.vlsi.fi/fileadmin/evaluation ... one118.zip

You can write to the GPIO registers directly using WRAM/WRAMADDR. Write 0xc017 (GPIO_DDR) to WRAMADDR, then 0x0002 to WRAM to set GPIO1 to output. Write 0xc019 (GPIO_ODATA) to WRAMADDR, then 0x0002 to WRAM to get GPIO1 to high. Write 0xc019 (GPIO_ODATA) to WRAMADDR, then 0x0000 to WRAM to get GPIO1 ...

Hi, Do you mean hardware reset using the xRESET pin? Because the SPI boot pins are partially shared with uSD/SD, resetting vs1163 during an SD access may be preventing boot from the SPI EEPROM, because the uSD/SD card is still providing data. (A workaround would be have a separate regulator for SD, ...

Where are you saving or sending the encoded data? If you are saving to SD card, then you may be experiencing large latency between some of the writes. Some cards behave better than some others in this respect. If it suddenly takes 200-500ms to write a sector, then the FIFO in vs1063a will overflow a...

Can you send or attach the file so I can take a look and Panu has something to test with when he comes back from holiday?

Does the playing of the file end immediately without playing anything?

Does the mp3 file have an ID3v2 tag?

Have you tried SCI_VOL = 0xc0c0 ?

It will lower the volume to 'zero' but keeps the analog power on so the ADC keeps working.

You're welcome. We have come to know the most probable issues and detect them from the small clues.

I can format the sd card at FAT12 or fat16? The comment only applied to the internal SPI FLASH. SD cards are pretty much always large enough to be FAT32. There may be some interactions if there are other USB devices on the same USB bus. Some machines may have internal card readers that appear in th...

Does the disk appear more quickly if uSD card is inserted?

Have you formatted the SPI FLASH disk on the PC? The default disk image on the SPI FLASH is not quite a valid FAT image. (It should be FAT12 for a disk of that size, but it isn't.)
