Hallo!
As I understand it, the V_ADP-pins of the 22pin-connector of the ?DA are for +5V to power the device. What shall I do with the USB_VDD-pin when creating my own cable? Has it to be connected to +5V, or just in case IŽd like the ?DA to switch on when connecting?
In addition to that, Do I have to connect all three pins (20, 21, 22) to +5V or is it enough to just connect one of them?
And: What I did not get clear until now, is GND for power and audio the same, are they internally connected? Or should I use different grounds for audio and power?
Many thanks in advance,
