Re: VS1053b - reducing general midi latency?

Right click solution (not project) in solution browser and select properties. In debugging tab there is autodetect. Can it find the chip? On OS X you can try to use the serial port. After all it is kind of BSD. If you are comfortable on command line, you could try something like: #set speed to 9600 ...

Re: Use the VS1005 bob

I assume you are using Rec because hiresrec writes wav files. The documentation found from https://www.vlsi.fi/fileadmin/software/VS1005/VSOS_Shell.pdf has a Rec control commands chapter. Basically you give string ~0209 and it would report level. I don't know if it works during pause but I don't see...

Re: VS1005 4-channel HiRes Recorder

This ended up rather long with many small bits of information. First the hiresrec has it's own player too. It is documented in the hiresrec document which can be found at least from VSOS_366_RootAndLibrariesSourceCode/docs/HiResRec_Bob2_v071.pdf which is the program distribution set from VSOS thread...

Re: Experimental high speed USB mass storage

Which board? Is it youur own design? Schematics?

What kind of content?

And what kind of clicking? Can you record a sample?

If you run umshs, What is the condition that you get correct playback?
Apparently reboot # isn't enough. Is external reset enough or do you need a power cycle?

Re: I want to convert from SPDIF to IIS output, can I use SRC function

Yes.

I don't have exact recipe in my mind, but if I2S is master, it is possible 48 -> 48 and 48 -> 96 Then both have same clock. Maybe even slave is possible if using auxsyncs. If I remember correctly, there are even reasonable drivers for this.

Re: Pitch / Speed Shifter for VS1010d

Now that you are playing, instead warning it would sound horrible, I'll tell how to bend the rules. There is a ratio: case IOCTL_AUDIO_SET_SPEED: currentSpeed = (u_int16)argp * (1.0/16384.0); { double speedPerShift = currentSpeed/currentPitch; if (speedPerShift < 0.68) { currentSpeed = 0.68*currentP...

More feature rich SPI NAND flash driver

Dear VS1010 users, I'm working on failure resistant and access restricted content system for VS1010 and while doing that I'm creating a security framework for such features. One step was the Chacha20 decryptor, and now is driver which tries to protect non-authenticated images to be flashed to SPI NA...

Re: Esp32 and VS1053 Audio Player

Hello and welcome to the forum, First of all I'm not familiar with Arduino ecosystem. The Baldram's VS1053 library seems to be targeting Platformio. Is it compatible with Arduino? Does the build have warnings? The library has player.isChipConnected() method which could tell if you have wrong SPI con...

Re: VS1010 USB I2S ADC

Two things has to happen:
1) I need to have time for that
2) There has to be a real use case and technical demand for such driver.

Or I need to have a feeling that writing USB audio device would be enjoyable somehow.
