Addressing
The setup needs one base address.
13 inputs and 3 outputs are reserved.
I/O
| Purpose | Offset | Length | I/O | Remark |
|---|---|---|---|---|
| Track position | 0 | 6 | I | 0…63 |
| Rotation direction | 6 | 1 | I | 1 = CCW, 0 = CW |
| New position | 7 | 1 | I | 1 = read new track position (puls 500ms) |
| At position | 8 | 1 | O | 1 = position reached (reset at new position flag set) |
| Sensor 1 | 9 | 1 | O | bridge loco sensor |
| Sensor 2 | 10 | 1 | O | bridge loco sensor |
