Hi
When measuring the voltage levels from the analog outs from the cape with a multimeter I get the following levels when doing in AnalogOut.ar( DC.ar( n ), DC.ar(1) ) in supercollider with n from 0 to 7. The board is being powered via usb connected directly to a port of my laptop.
(V)
0 4.86
1 4.86 - 4.89
2 4.85 - 4.89
3 4.86 - 4.89
4 4.86 - 4.89
5 4.86 - 4.89
6 4.86 - 4.89
7 4.86 - 4.89
5v - 4.86 4.89
Is this normal ?
edit: The voltages are constantly jumping between the two values. I can't get a constant value.
edit2: Connecting to a powered USB dock I get oscillations between 4.94 and 4.95. Connecting to samsung USB phone charger I get oscillations between 4.89 and 4.90. It's not possible to get a constant voltage from the bbb ?
Thank you,
