title: Raspberry pi 4 controle GPIO with java
body: <p>I want to controle a 16*2 lcd display on my raspberry pi4 with java. The problem is that Pi4J - the solution to modify the gpios with java is not updated to pi4. Is there another solution? This error occures when I start the programm:</p>
  <pre><code>pi@raspberrypi:~/desktop/gpio $ sudo ./start.sh
  </code></pre>
  <p>&lt;--Pi4J--&gt; GPIO Control Example ... started. Maista
  Unable to determine hardware version. I see: Hardware   : BCM2711
  ,</p>
  <ul>
  <li>expecting BCM2708 or BCM2709.
  If this is a genuine Raspberry Pi then please report this
  to projects@drogon.net. If this is not a Raspberry Pi then you
  are on your own as wiringPi is designed to support the
  Raspberry Pi ONLY.</li>
  </ul>
