- Motor run and hold current per axis, sent on every connection because the controller forgets them at power-off
- Direction reverse per axis
- Platform position readout in degrees
- USB serial, or TCP on port 2323 for a board on WiFi (firmware 1.3.0 or newer)
- Safety: moves are refused until the platform is calibrated; a move that stalls, times out or stops short of its target is stopped and reported as an error

## Requirements

- INDI 2.2.0 or newer
- OAPA firmware **1.2.1 or newer** (1.2.2 recommended). Older firmware connects, but speed and Abort are ignored and the driver logs a warning.
- OAPA firmware **1.2.1 or newer** (current release 1.3.5). Older firmware connects, but speed and Abort are ignored and the driver logs a warning.
- For automatic correction: KStars 3.8.2 or newer. The feature is marked preliminary in KStars.

## Installation

The driver is part of INDI core and needs no extra dependencies. Connect the controller by USB; it appears as `/dev/ttyUSB0` or `/dev/ttyACM0`.
The driver is part of INDI core and needs no extra dependencies. Connect the controller by USB; it appears as `/dev/ttyUSB0` or `/dev/ttyACM0`. A board on WiFi running firmware 1.3.0 or newer is reached over TCP instead, on port 2323.

## Configuration

1. In the Ekos profile editor, select **OAPA** under Auxiliary.
2. In the INDI Control Panel, choose the port on the **Connection** tab and click **Connect**. The board resets when the port opens; the driver waits for it.
2. In the INDI Control Panel, choose the port on the **Connection** tab and click **Connect**. The board resets when the port opens; the driver waits for it. For a board on WiFi, set the connection mode to **TCP** and enter its address and port 2323; the firmware serves one client at a time, so close its other clients first.
3. Set **Calibration** (steps per arcminute) for both axes. Until you do, every correction is refused. See [Calibration](#calibration) below.
4. Check the directions once, as described in [Direction check](#direction-check).
