That's the PX3544 whitepaper, it's not the full datasheet with full pin-out and functional diagram.

I used two variable resistors from each of the two black points I circled and set them both close to 15 ohms. I went to a variable resistor and then straight to a ground
I think this is the problem. Only 1 (the one on far right) of the 4 original resistors ground in a real GND. If we just had the PX3544 datasheet...
