Need SigmaStudio 4.5 (32-bit) for USBi Serial usage

Category: Software
Product Number: Adau1707

I am working with an ADAU1701 SigmaDSP in a product that uses USBi over a serial (UART) bridge implemented by an external MCU (USBiSerialConvAddress). Unfortunately, the 64-bit versions of SigmaStudio do not support USBiSerialConvAddress, which prevents communication with the DSP.

This is a known limitation, and the recommended solution is to use the 32-bit (x86) version of SigmaStudio 4.x, which fully supports USBi-serial.

Does anyone have a download link for one of the following installers? -

SigmaStudio 4.6 (32-bit / x86) - or SigmaStudio 4.5 / 4.3 (32-bit / x86)

This will be used on Windows 10/11 x64 with an ADAU1701 and serial USBi bridge. Thank you very much for your help.

  • Hi,

    I'm using "adi_sigmastudio-rel4.6-x64.exe" on Windows 7, and the USBi programmer works.
    However, installing this version of Sigmastudio was a bit of a hassle because I had to download a few utilities first, without which the program wouldn't install. But I managed to do it.
    I have these files on another computer. I can share them if you'd like.
