Hi,

 

ich have build the AOUT_NG for my Seq4, but no CV on any Pin goes out.

In CV menu AOUT_NG is selected.

Gate is ok.

Soldering is ok, no bridges or disconnections.

I measured directy on JP1 the DAC output, but no voltage are here.

 

The connection between  J1 on AOUT_NG and J19 on LPC17 now is ok (Pin3 on RC1), for the first time I have connect Pin3 to SO, Pin4 to SC and Pin5 to RC1 :-(.

Is my DAC damaged now?

 

Have anybody a idea?

Hi Markus

 

How long is your cable between the LPC17 and the AOUT_NG? I had some trouble in the beginning, when I had a cable which was longer than 10-20cm.

 

I don't see any reason, why you should have damaged the chip with the wrong connection you mentioned. As long as you don't connect these pins to +/-12V, you should be save.

 

cheers

Andy
