Re: VS1005 4-channel HiRes Recorder v1.00

Dear Forum Members, for quite some time there has existed a need to overhaul the HiRes Recorder.

Re: Patch to fix SPI flash writing in VS1010D

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 ...

Re: VS1010 RecPlayExample v0.30

Hello! Here is a new and updated version of the VS1010 Recorder / Player. There was a significant bug in the old version, namely that it could only be run from the SD card. This new version can also be run from SPI Flash. Note that if running any software from SPI Flash, it is highly recommended you...

If AICTRL = 1x (1024) then autogain is disabled and value of AICTRL2 is not important. Am i correct? Yes, set SCI_AICTRL1 = 1024, and yo...
