Actually yes we can say so.
Micro-controller code is completed. That includes all SPI peripherals management, LCD, IR sensor, USB communication etc.
DSP code is nearly done.
Most of the remaining work is on the control application. It's of course already communicating with the board and I have big chunks in place under Windows and Linux.

I must say. Isn't this a vast programming task? A couple of platforms and a gui as I understand. Are You doing all by Yourself? (I'm in the programming business myself, database oriented applications.) I'm impressed even if You wouldn't succeed.
Best wishes.

would it possible to order a board without the rca connectors? i don't need them and desoldering is alway a risk to damage the board. i only need the digital inputs and the usb connector.

Do the digital inputs and outputs have transformer isolation?

Yes that's a lot of work. There are other things coming on top such as schematics, PCB design and filters design. It's going to be fine

So I'm right now looking at quotes from the PCBA manufacturer. Lead time is 40 days and I'm requesting first 1 board to make sure there's no issue with assembly (there's over 400 components on each board). I'll post pictures of the first board.

That should be doable, to be confirmed.

All outputs are isolated (5 transformers). Input is not isolated - I made here the assumption that the line is isolated on the source side, which is usually the case in my experience.

I'm doing as fast as I can. If there's no problem with component sourcing then the batch will follow shortly after the first unit has been received.
