For educational purposes, our professors have DB25 ports on our laboratory rooms, and of course we can only simulate our assembly codes in there
Our professor said that it might not be possible to control 8 LEDs (terminal
D0-D7) using a USB to Parallel Port(DB25) Converter,
We're simulating, for example, We're sending binary information to the port that would do this:
D0 On D1 On D2 Off D3 On D4 On D5 Off D6 Off D7 On
It would be
mov al, 11011001b, as I've said we've done this on PC's that have available DB25 port
Is it possible to send an 8-bit data through a USB to Parallel Port(DB25) Converter?
