Multi-IO Expander

[mgd]

Hi Nerds,

I'm still trying to figure out how to play my distingEx via I2C. Preferably Poly Wavetable but SD Multisample, Macro Oscillator 2 or Poly FM would do as well. Has anybody of you guys got this to work and would be willing to share a simple project showing how to do it? And if there are special settings on the side of the distingEx provide these too?

Kind regards,
Michael

Hi Michael, 
I thought someone would have answered you by now;
Have you been able to connect any i2c device and communicate with it successfully?
I haven't done much with yet but I have been able to change values on Macro Oscillator. 
PM me if you like and I will walk you through my setup : D

Thanks for that offer - I just read this together with Thomas's answer. I'm trying Thomas's project first and hopefully will continue from there.

Kind regards,
Michael

I just unpacked a new distingEX, updated to the latest firmware. Checked the I2C Address which was 0x31 by default.
I2C Cable connected and using the 3.3V Pullup of the Multi-IO, pullup in the disting disabled.
NerdSEQ set up to I2C PortA -> Out
Pattern I2C/Multi. Columns 1-3 set to A-EX.VPL  31   1-3

Just works, PolyFM.
Project attached.


If that doesn't work with you Michael, then lets try a loopback test to see if the ports are working.

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
