12:6 Audio Mixer - Testing

Continued from Part1

So.. i spent a day mounting all of the boards/connectors in a 1U case to make it a little easier to test.
An arduino nano has been mounted in the box for now, this will be used to interface to my pc for testing purposes, normally the raspberry pi will connect directly to the mixer.

Inside



A small sketch was written for the arduino to pass on the config bits to the FPGA from the pc via usb.
A GUI was written in C# (my fav way to create gui these days!) to send the control to the mixer via the arduino.

Here is what you get and so far all seems to work as expected :-)

Control Test GUI



The list next to the output sliders is used to select what channels are mixed to that output, blue are active.
The input levels do not effect the squelch threshold.

Maybe next i should look at actual gain levels in dB etc.. tbc
