<p class="MsoNormal" style="margin-bottom:12.0pt">Hi,<u></u><u></u></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">I want to read USB data from a Gamepad in Erlang to play a game.<u></u><u></u></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Programs like JoyToKey and Enjoyable convert Gamepad inputs to keyboard input, but they only send 1 character so using io:read would require an additional "return" press to send the input.<u></u><u></u></p>
</div>
<p class="MsoNormal" style="margin-bottom:12.0pt">Where do I start looking to learn how to read gamepads? I've heard that Erlang ports can be used to interact with the world outside the Erlang shell but I have no idea where to look. I found erlang-serial on
Github but had trouble installing it <a href="https://github.com/tonyg/erlang-serial/issues/14" target="_blank">
