RAMMP HMI / joystick (RJM)

In use

Touch HMI and 3D hall joystick (X, Y, twist), haptics over a DRV2605. It follows RAMMP UI spec V2: locked, drive, seat, settings, diagnostics, log and bench screens.

The PRD listed "PACE Stick" as a future candidate. This node already exists.

Questions for SPACE

  • The joystick is the highest-consequence input on the chair. It needs a point-to-point link plus the hardwired e-stop under ADR-0003 and ADR-0006, not a multidrop slot.
  • It is an ESP32-P4 with a W5500, so it could use the P4's RMII MAC instead. That is evidence for ADR-0010.
