Dear Forum Members, for quite some time there has existed a need to overhaul the HiRes Recorder. The existing HiRes Recorder has a few issues: 1) It is large, barely fitting in VS1005's memory, so there is no room for expansion. 2) Updating the LCD is time-critical: update too much at a time, and re...

Dear Forum Members, attached to this message is VSOS Kernel v3.61 for External and Internal SPI Flash. This version is a minor modification, designed to fix one specific missing feature. The earlier versions would work with FAT file systems (on SD cards or USB sticks) which had a cluster size of a m...

Here's a patch that fixes inconsistencies we discovered with a Linux PC writing to the SPI flash of VS1010D using USB mass storage in runlevel 4. The problem may occur in other operating systems also, so this patch should be applied to all VS1010D boards that have an SPI flash installed. One thing ...

Hello! Attached to this message is a new VS1005 audio player, PlayDirP.dl3. PlayDirP is an audio player capable of playing audio files a directory at the time. It is much like PlayDir, except that it allows for two separate volume controls, e.g. one volume control for the analog outputs, and another...

Hi! I am adding a bit to what Hannu wrote. I would like to clear some moments. If AICTRL1 = 0 that autogain is enabled and AICTRL2 value is used as a maximum gain.
