<div class="markdown_content"><p>Hello everyone!</p> <p>I am using this port expander <a href="https://www.abelectronics.co.uk/p/54/io-pi-plus" rel="nofollow">https://www.abelectronics.co.uk/p/54/io-pi-plus</a> with 2 MCP23017 and I have a problem with outputs.</p> <p>If I startup my RPI and this IO board at the same time I can not operate with outputs. There is 5V and every pin on this board. But If I startup Raspberry PI first and this IO board in about 10s, I can operate with outputs normal. I can not understand why is this and how to fix it, so that this will work normal at startup of both (RPI and IO board).</p> <p>I am using this library <a href="https://forge.codesys.com/forge/talk/Runtime/thread/a2dd4dd45f/">https://forge.codesys.com/forge/talk/Runtime/thread/a2dd4dd45f/</a></p> <p>Best regards</p></div>
