node-red-contrib-xkeys_ledrate v0.1.0

node-red-contrib-xkeys_ledrate

This is another in a collection of Node-RED nodes which enable access to X-keys physical devices.

It is planned to have a dedicated Node-RED node for each X-key event of interest (button, jog, joystick, etc.). These will communicate, using MQTT, with a lightweight X-keys server, whose sole purpose is to mediate access to any physically attached X-keys devices.

This xkeys_ledrate node configures the LED flashing rate of any _xkeys_led nodes.

Installation

This node requires xkeys-server version 0.0.4 to be running. Please follow the instructions at the xkeys-server development repository to install it or, to upgrade an existing installation, see the xkeys-server upgrade instructions.

The node-red-contrib-xkeys_ledrate node itself is best installed from Node-RED's Palette manager. Go to the Palette manager's Install tab and search for node-red-contrib-xkeys_ledrate; then Install it once found. If not found, press the Refresh module list button (two semicircular arrows) and search again.

When installed, a new LED rate node will be found in the palette tab in the dedicated Xkeys category.

Usage

The node's configuration editor can be used to set the frequency of LED flashing for any xkeys_led node. A setting of 1 produces the fastest flashing while a setting of 255 produces the slowest.

Authors and acknowledgment

Many thanks to P.I. Engineering for the donation of several X-keys devices for development and testing.
