Re: VS1005 4-channel HiRes Recorder

Short answer: No.

Long Answer:
USB requires 60 MHz clock which is too slow for hiresrec. Hiresrec is big program and there isn't memory available.

And if it was technically possible, someone (probably me) would have to write the USB CDC driver for VS1005.

Disable SPI1 video out in boot

Dear VS1010 user, I designed something silly and made a mistake. I had P and N FETs connected to XCS1 and MOSI1. Those two pins are used in SPI video output. To prevent self destruction I had to find a way to prevent driving those transistors on at the same time. This meant that I had to disable the...

Re: Changing player.volume question

A lot of things are possible with the player. If you are playing MP3, there will be some silent part because how MP3 just works. I assume, you are still using ROM PayerCallback(). If you give + or - through UART, it adjusts the volume. Have a look at: http://www.vsdsp-forum.com/phpbb/viewtopic.php?t...

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...
