SHUTTLE(1)

NAME
shuttle - control HAL pins with the ShuttleXpress, ShuttlePRO, and ShuttlePRO2 device made by Contour Design

SYNOPSIS
loadusr shuttle [DEVICE ...]

DESCRIPTION
shuttle is a non-realtime HAL component that interfaces Contour Design's ShuttleXpress, ShuttlePRO, and ShuttlePRO2 devices with LinuxCNC's HAL.

If the driver is started without command-line arguments, it will probe all /dev/hidraw* device files for Shuttle devices, and use all devices found. If it is started with command-line arguments, it will only probe the devices specified.

The ShuttleXpress has five momentary buttons, a 10 counts/revolution jog wheel with detents, and a 15-position spring-loaded outer wheel that returns to center when released.

The ShuttlePRO has 13 momentary buttons, a 10 counts/revolution jog wheel with detents, and a 15-position spring-loaded outer wheel that returns to center when released.

The ShuttlePRO2 has 15 momentary buttons, a 10 counts/revolution jog wheel with detents, and a 15-position spring-loaded outer wheel that returns to center when released.

UDEV
The shuttle driver needs read permission to the Shuttle devices' /dev/hidraw* device files. This can be accomplished by adding a file /etc/udev/rules.d/99-shuttle.rules, with the following contents: SUBSYSTEM=="hidraw", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0020", MODE="0444" SUBSYSTEM=="hidraw", ATTRS{idVendor}=="05f3", ATTRS{idProduct}=="0240", MODE="0444" SUBSYSTEM=="hidraw", ATTRS{idVendor}=="0b33", ATTRS{idProduct}=="0030", MODE="0444" The LinuxCNC Debian package installs an appropriate udev file automatically, but if you are building LinuxCNC from source and are not using the Debian packaging, you'll need to install this file by hand. If you install the file by hand you'll need to tell udev to reload its rules files by running `udevadm control --reload-rules`.

A warning about the Jog Wheel
The Shuttle devices have an internal 8-bit counter for the current jog-wheel position. The shuttle driver can not know this value until the Shuttle device sends its first event. When the first event comes into the driver, the driver uses the device's reported jog-wheel position to initialize counts to 0. This means that if the first event is generated by a jog-wheel move, that first move will be lost. Any user interaction with the Shuttle device will generate an event, informing the driver of the jog-wheel position. So if you (for example) push one of the buttons at startup, the jog-wheel will work fine and notice the first click.

Pins
All HAL pin names are prefixed with `shuttle` followed by the index of the device (the order in which the driver found them), for example "shuttle.0" or "shuttle.2".

(bit out) (prefix).button-(number)

(bit out) (prefix).button-(number)-not
        The momentary buttons. "(number)" identifies which button corresponds
        to the HAL pin. The "button-(number)" pins are True when the button
        is pushed, the "button-(number)-not" pins are True when the button
        is not pushed.

(s32 out) (prefix).counts
        Accumulated counts from the jog wheel (the inner wheel).

(s32 out) (prefix).spring-wheel-s32
        The current deflection of the spring-wheel (the outer wheel).
        It's 0 at rest, and ranges from -7 at the counter-clockwise
        extreme to +7 at the clockwise extreme.

(float out) (prefix).spring-wheel-f
        The current deflection of the spring-wheel (the outer wheel).
        It's 0.0 at rest, -1.0 at the counter-clockwise extreme, and +1.0 at
        the clockwise extreme. (The Shuttle devices report the spring-wheel
        position as an integer from -7 to +7, so this pin reports only 15
        discrete values in its range.)
