I have a question as to how to implement the Parallel Port of Hydra. Since it was possible to Pande 2.
What are you planing to use it for?
ParallelPort class is part of the GHI premium library, which is available for the Panda, but not for the Hydra which uses the OSH Library.
You will have to implement the equivalent functionality yourself.
Which, TBQH, wouldn’t be that difficult. See here for an overview of the process:
It would be very convenient to control the eight outputs by sending back an array of bytes
