Hi Attila,
I am attaching the connection diagram showing my system. Those solid blue components (AD2 and PS) are purchased from Digilent. As I understand, the default setting is that when the aux power supply is detected, power would not be drawing from the USB. So, I do not understand what is causing the overcurrent when attempting to start up
the waveforms. According to the reference manual, it is not recommended to disable the current limit. Why would I still need to disable the current limitation in my current system.
If possible, can you mark up my drawing (or provide a proper connection diagram) if there is a problem with my current setup.
Thanks.
