LPT Switch
Lilwolf:
Ok everyone... This will be fine for a one player setup...
but take a look at the diagram... and tell me what happens when this happens...
Assume player 1 is buttons 1-10, player 2 is 11 - 20..
Hoagie_one:
thats a good questions....and I can only say, I'll tell ya when its built, lol
Trimoor:
I'm guessing it repeatedly scans every switch in the matrix, avoiding this problem.
Besides, button 11 is on pin 4 while button 1 and 2 are on pin 3. What's the problem?
In any case, we'll find out soon.
Hoagie_one:
Just ordered all the diodes i need for this, just gotta get a few more terminal blocks.
Question. Whats teh best way to test for ghosting or interference? Should i just rig all 60 buttons combinations to one button press and see what teh results are?
Projekt Produkt:
The driver being used sees the first 30 positions as joy1 and the second 30 positions as joy2. So the driver might at least reduce some ghosting, if any exists, by guaranteeing that two players will have dedicated lines at the port.
What would be a good way of testing for ghosting. If someone could say what condition might show some let us know and I'll hook those up and give em a push.
