<div class="markdown_content"><p>I really appreciate your changes on the library regarding the polarity of inputs. Additionally I tweaked it a little bit to controll this for each port with a variable.</p> <p>What do think?</p></div>

<div class="markdown_content"><p>Good morning,<br/> I made a small change to the library i2c - MCP23017. </p> <p>Now when the pins are set as inputs, the signal arriving at the PLC reflects the opposite logical state with respect to the input signal.<br/> In practice, when the pin is set to 0V, the high signal arrives on the PLC. </p> <p>I think it's easier to manage inputs this way.</p> <p>I provide both the normal library and the compiled library.</p> <p>What do you think?</p> <p>Massimo</p> <p><a class="" href="https://forum.codesys.com//download/file.php?id=4313" rel="nofollow">I2C_MCP23017_Confa.compiled library <span><span>[160.9 KiB]</span></span></a></p> <p><a class="" href="https://forum.codesys.com//download/file.php?id=4312" rel="nofollow">I2C_MCP23017_Confa.library <span><span>[304.06 KiB]</span></span></a></p></div>
