Getting hot is not a good sign. You could have a short-circuit somewhere, which could cause for example two output pins driving against each other. If you have a separate 3.3V regulator for the SD card, then running VS1005 with 1.8V IO voltage would also cause current to be sinked through the protec...

You are using disk D:
Playing >> name of my track
but then doesn't play anything and immediately displays
Goodbye!

What's the audio format of the file you are trying to play?

The audio formats have varying audio block sizes and natural size of number of samples they output at once. It might also depend on the individual file (samplerate, bitrate). The more samples are sent to the audio output at once, the less overhead. So, decoders want to send as many samples as conven...

Unfortunately vs1053b doesn't have the same "patch hooks" in the AAC decoder, so supporting DASH files is pretty much out of the question unless you switch to vs1053a. You'll have to test if flac is possible. It's all about the SPI transfer rates and the latency of the storage you have. If you use S...

Thanks for the report. Due to holidays it will take at least 3 weeks before Henrik is back and can take a look. You could check if the same issue exists in the older version: http://www.vlsi.fi/fileadmin/software/VS10XX/vs1053-vs1063-pcm-recorder-130.zip At least the profiles have different CRC's in...

Those files seem to be MP4-AAC files in a DASH container. You should see 'M4' in HDAT1. The DASH container is the reason why the playback stops after 10 seconds. We have added code in the vs1063a patches package so that vs1063a will play the DASH files, but I haven't (yet) checked if the same is pos...

Could you send me one of the failing files to our support at vlsi.fi address?

The files probably do not have an ID3v2 tag. Does your player make use of the ID3 tags in any way?

1. Which audio format(s) are the files?
2. Does the playback always stop on the same files? Are other files playing more than 10 seconds?
3. Does the playback continue normally from the next file?
4. Is it exactly 10 seconds, or approximately?

The best possible mute is implemented using a relay, which keeps the amplifier input at zero under software control. When turning on, the mute needs to be active until the vs1053b has biased its output on the other side of the DC block. When turning off, the mute is first engaged, then the vs1053 is...

How can I load the plugin and the .img file. Hope you can help? The plugin files contain both the data and the C source code to upload the data. You have to provide the SCI register write function in your own source code. Also, the vsx053 Ogg Vorbis encoder application documentation tells how it is...
