A viewer recently asked about connecting a digital arcade joystick (ex. a Sanwa with the 5 pin Dupont type connector) to the X1 or X2 jacks on the XBOX Adaptive Controller.
What he was seeing was odd values — the XBOX AC would show “full left” and “full down” (or visa versa). This is because the X1 and X2 jacks require Analog input — in other words, potentiometers. (Or an equivalent.)
I provided him some technical details on why this is, and why it can’t be (easily) done with discrete resistors. I’m working on possible solutions. In the meantime, here’s the info. I hope it helps others.
