This code replaces the hat switches with a mini-joystick as POV controller. The new axis are reported as Rx and Ry. The mini-stick X axis is read on pin F4, the Y axis on F5. The mini-sticks I used in my mod and mockup are discontinued, but this one should work (and, more importantly, fit into the 3DPro.)
Turns out you will need to run only two signals from the mini-stick to the controller and the 3DPro's cable can hold them. The X2 and Y1 signals are not used by the adapter and can be repurposed. You still need to run 4 wires through the handle -- one for GND, one for +5V, one for Rx, and one for Ry.
Inside the 3DPro the cable breaks out into 11 seperate wires and connects to the sticks main PCB. The key to the colors is:
Code: Select all
1 Orange X2 Axis 6
2 Grey X1 Axis 3
3 Brown Y1 Axis 11
4 White Y2 Axis 13
5 Black GND 4
6 Purple Button 1 2
7 Blue Button 2 7
8 Shield Shield
9 Red +5V 1
10 Green Button 3 10
11 Yellow Button 4 14

. Seems there is some great progress being made on that front in recent months. Thanks too for all your work designing a circuit board to support both projects. Since I only own the 3DP, I think I'll stick with 3DP-Vert and build it myself. More compact, less parts, less cost and most importantly, more fun
