Thanks for this info and the schems! It looks like it's still working - whew - even after I stupidly tried to measure a +28v signal :o The voltage I'm seeing (0.5v now on my meter) appears to be some kind of floating / hi-Z state. Or possibly some tiny reverse leakage from the high-side diodes. It appears to go away once I set and arm the GPIO as a logic input and click "run" Moral of the story: do all of the above steps before connecting sensitive gear. The FPGA sets the GPIO apparently only after the "run" command is selected in Digilent software (on my black legacy AnalogDiscovery)

Hey all, First time poster, long time recommender of the excellent AnalogDiscovery and Digilent software :) I got the AnalogDiscovery Legacy (black one) and almost blew up an important project today because the logic analyzer was outputting a voltage on it's pins....anyone know why this is / if it is broken? I measured around 0.9V on DIO 0, 1, etc. Thanks so much! P.S. thanks so much for supporting old Windows OS!
