Multi-IO Expander

[XORadmin]

Thanks for providing this project.

Loaded the project. No sound from the distingEx. Looking into it it basically does what I had tried myself (so not only a stupid user error ).

How would I do the loopback test?
Connect I2C A with I2C B is the easy part. Which settings on the NerdSEQ?

Kind regards,
Michael

Indeed, connect the 3 lines to each other.

Use only 1 pullup to 3.3V (doesn't matter which one...you can try also to swap to the other one on a 2nd test).

Load the project and play the pattern. Both LED should flash and in the mapping screen you see the 'loopback' reception in the first line 000 466 6AA B99.

If that works, try the other way around (set the I2C Port A to 16n->NS and port B to out. Change in the track setup to B-SC.CV)
