preenFM is going to Eurorack

klangFM:
Nice to read this.
I is more concret to open the gates for CV in?
It would be nice to open 2 input for 2CV and Gate/Trigger signals to use it in "Matrix".
I don´t know how a Gate could to be implemented. At first it make sense for me.
To scale voltes down to 3,3V I can try it to do.

I'm away from my computer still for 8 days.
Have a look at this post :

klangFM:
Thanks,
who can compile me this github stuff: acdcIN?
I'am analog.
Question: AD controll range is 0-3.3V. For a scaling opamp one use an inverting desing and output is 3,3V to V.
Therefore it is better to invert input range in acdcIn firmware.
Possible?
As far I get a compiled version I test it and draw a little schematic with board.

lokki:
i can compile the firmware for you if no one else does :-)

lokki:
xavier i get this when i try to compile the adc branch:
