Hi Amin,

I understand from Ashlesha that you've agreed to help, many thanks!

I never closed this case; I just didn't get an answer to my last post.

The open issue is mixing inputs and outputs on a single GPIO header of a DE10-Nano. Simple example: GPIO_1[1] = Input; GPIO_1[2] = Output; (and perhaps GPIO_1[3] = BiDir). My original post gives more detail including things I tried unsuccessfully.

Seems this should be easy, but I haven't figured it out, and, so far, no one has furnished the explanation.

Thanks again,

Bill
