Ribbon cable that services the limit switches on the arm
« on: February 13, 2018, 10:11:36 PM »
There's a single ribbon cable that runs from the gripper end all the way to the logic board. It has 13 wires. One edge is painted black - that's the index for wire 1.

There are 9 limit switches along the length of the run. These are divided into 3 groups. Each group shares a common ground signal.

Here's the wire definition for the 13 signals on the ribbon cable, grouped.

1 Ground
2 Cube touch DIO-0
3 Wrist down reverse
4 Wrist up forward
5 Gripper closed reverse
6 Gripper open forward
7 Climber DIO-4

8 Ground
9 extension limit far reverse
10 extension limit near forward

11 Ground
12 arm rotation limit up reverse
13 arm rotation limit down forward

Do not use this cable as-is.

We need something new.

I messed up while attaching the cable to the limit switches.
The table above has been changed to reflect my error.
