==== Identifying key names ====


Open a terminal and type the following command:

<code>evtest</code>

Then select your intended controller and press the button on your controller. The detected input will then be displayed like so:

<code>Event: time 1614795871.549381, type 1 (EV_KEY), code 99 (KEY_SYSRQ), value 0</code>

Look for the key name in parenthesis and its value when depressed after the “code” number. In this example, the key name would be KEY_SYSRQ and its value would be 0.

=== Anlog Joystick on this cheap USB-encoder ===


Quelle((https://www.instructables.com/Zero-Delay-USB-Encoder-True-Analog-Joystick-Modifi/))



When I discovered these cheap CY-822A / USB Joystick X1 - Game Control Board USB Joystick Encoders on Ebay and Amazon I was puzzled by their description and construction.

A lot of people like to make their own input devices and controllers and these are a cheap way to get started - but just switches are not always what you want.

Despite the Analogue description its a very Digital device.

Bessere Möglichkeit mit dem gleichen CY-822A: Brücken, damit das Ding direkt in den Analogmodus bootet:
