Alright, we’ve all heard that the triggers on official DC pads lags. Some people say they do, some people say they don’t, and some say there are two different points that can be used, and one of them doesn’t lag.
I hate indeterminate fuzzy bullshit, so I want to set the record straight once and for all, and I’m willing to scrap a couple of DC pads if needed; after moving and organizing my toys, I realize I have plenty.
What I propose: Take an official DC control pad. Run one wire from a button (‘A’), a direction (‘Down’), a trigger (‘L’), and ground. Take the three button wires, solder them together and run a single wire from that. Connect the single wire to one leg of a switch (I dont care what kind, and it shouldn’t matter) and run the ground line to the other leg. Now, with a single button press, the digital button, direction, and trigger can be activated at the exact same time.
Load up CvS2, go to training mode, and turn on key display. Press and release the button multiple times. The reporting on CvS2 is by frame; if there is no lag and all three activate and release on the same frame, we’ll see one row of all three inputs, and nothing when released. If there is even a frame of lag on input, we’ll see the digital inputs (Down and A) on one row, followed by all three once the trigger lag is done. If there is even a frame of lag on release, we’ll see a row with only the trigger, followed by nothing.
Another option would be to use a normal cherry microswitch. Wire ground to the COM pin, a trigger to the NO pin, and a digital input to the NC pin. Repeatedly press and release the switch. If there is no lag on the trigger, we’ll see only a single input on each line. If there is any lag difference between the two, we’ll have a few lines showing inputs from both.
So, I need two things before I start hacking.
#1. Any flaws in this plan? Any better ideas to test this?
#2. What are all of the different points to connect to the HAL effect sensor used on the board? I know there are at least two, but I dont know where they are. Please point out all that you know of.
Hoping others will find this usefull…
