Parallel port dongle: ACK pin isn't connected

Post by IanO »

I'm confused. In SpokePOV.py, you check the Acknowledge pin (Pin 10) to test for a connection. But this pin is not connected on the dongle! Pin 4 is connected to #RESET, and this is set high when initializing (setData(0xFF)). But neither this nor any of the other data pins are readable.

You would need to enhance the dongle to reliably check for a connection. In the meantime, the connected() method should not be used. This bug was masked by the previous bug (using "~" instead of "not").
