<p>Unfortunately I am not able to force output even IO variable is set to "16#00"</p>
<p>(I am using RPi v3)</p>
<hr/>
<p>Update:<br/>
There is a problem with IO configuration -> its fixed FF (all inputs)<br/>
Maybe I cannot call init procedure properly....</p>
<p>I change it in library to 16#F0 to have half port as in and half as out and it works..</p>
<p>Can someone change it during operation??</p></div>I2C libraries MCP23017_16_IO2020-02-27T16:43:43.937000Z2020-02-27T16:43:43.937000Zciorry86https://forge.codesys.com/u/ciorry86/https://forge.codesys.com03e8379081c3d9188aa7150eabc57b07afe7df35<div class="markdown_content"><p>Good afternoon,<br/>
