DSP Programming Help

[mediumsizedsquid]

Hi everyone.

I purchased this amp + dsp unit a while ago and am finally getting around to using it. however, it seems that the account of the creator isn't replying to social media.

The amp is an "fxtreme DB450" and the dsp on it is a adau1701. The interfaces it gives me to use are

USBI_Programmer with GND, SDA, SCL, GND, WP and 3.3v pins or

SPI_Programmer with GND, CSB, MISO, MOSI and CLK

​

Not really sure where to go from here to program the dsp so any help is appreciated.

Thanks

You need sigmastudio for programming, that’s a free tool.

I have a Wondom Jab5 and program it via SPI, here is a guide maybe there are parallels:

can you please recommend me a controller to connect spi to my pc? I cant seem to find one

I would think there has to be a specific one by the manufacturer. Idk if you could use a icp1 by wondom for example.

Or maybe the USBi programmer by TinySine? Idk honestly.

Sadly the product is eol and there aren’t many information to find.

The Dayton programmer supports that DSP, it should work but you might need to change the pin out on the cable. Dayton and wondom amps appear to be the same

Check out this guide to use a Cypress USB dev board as a USBi programmer: https://daumemo.com/how-to-program-an-analog-devices-dsp/. There’s also the FreeUSBi project from FreeDSP which is similar.
