LEFT, RIGHT, and GBUF are self-biasing, so if you don't use the analog output, you can leave them unconnected.

For debugging purposes (to monitor the recording), they could have the resistor+capacitor to ground circuit.

2 - there is no non-volatile storage (other than ROM) in vs10xx chips, so you need to load these patches, plugins, or applications after each reset. Your SCI register dumps look correct. Depending on the code you upload, you may need to start it separately by writing the specified start address to S...

1 - You also need at least xCS of vs1053b connected, preferably also xDCS. Being able to see the state of DREQ is also pretty important, although with care you can get away with having access to it. 2 - The patch / plugin is something you need to load every time after reset. The upload is performed ...

My MIDI message sequences typically are 2 and 3 byte values. Where does the 0x00 go in those sequences? Before every and each one of the bytes you send. 3-byte commands become 6-byte transmissions. In addition to sending the proper bytes through SDI, is there any additional configuration of the VS1...

1. coff2allboot is newer, and it supports more boot image formats (and also overlay linking for vs1000). 2. .coff is an object/executable format. You can convert it to SPI boot image using coff2allboot. 3. If the project is based on the VS1000 Audio Module, the solution consists of 4 separate progra...

I think you would need to adjust all of the sample positions in all of the Ogg frames accordingly.

Quick and short (or not) answers: - Yes, line in and line out can be used at the same time. The default encoding function uses the analog output for record monitoring. In vs1063a Codec modes provide both at the same time. - There's a VSIDE template for audio in/out (for both vs1053b and vs1063a). Th...

(HE-)AAC should not be any different than mp3. It does decode directly from the stream buffer though, so DREQ probably goes up more often. Check that you don't send more than 32 bytes after checking that DREQ is high. Are you using the vs1053b-patches package? Also note that mp3 resynchronizes easil...

If you're playing HE-AAC regularly, I would think you're not looking at the lowest possible power consumption, and thus I would suggest always using 5.0x clock instead of 3.5x+1.0x. That would also allow to use higher SPI clock (up to 15MHz instead of 10.5MHz). You could change CLOCKF and your SPI s...

Hi, I can play your file without issues with vs1053b with and without the vs1053b-patches loaded. - SCI_STATUS changes to 0xC and than 0x48 (was 0x40) It sounds like vs1053b gets reset from somewhere. It could be an erraneous write to SCI (software reset), or something external. The most probable is...
