Hi! I’m working with a Hydra, and despite the many sockets, I’ve run into some problems where some of the GPIO pins are giving me some trouble:
Sockets 10 thru 12 :
I don’t know what to call these pins since they’re listed as LCD pins on the schematic and not GPIO’s. I was also having some trouble using these sockets for the load module even though they’re marked as Y sockets.
Socket 4 :
Pins 7,8, & 9 can all be assigned in the program with no problems as well as read them in the program if they’re not connected to anything (just floating wires). But when I connect any of them to either a +5V or a 0V to drive them, the program crashes with an exception or something.
Pin 5 works fine, but when I’m driving it high and try reading analog values from pins 3 and 4 in the same socket, those two voltages jump up when a +5V’s being delivered to pin 5. I’m guessing this is due to weak isolation in the analog reading mux? (pin 5’s also an analog input).
Any thoughts or ideas? They’re all used for digital reading, so something like the MaxO isn’t a viable solution.
