<div class="markdown_content"><p>Hello <a class="user-mention" href="/u/macieksz/">@macieksz</a>, did you find a solution to your requirement? I'd also like to get a CAN-FD operational on Raspberry Pi with CODESYS. Do you have any suggestions? Thanks.</p></div>

<div class="markdown_content"><p>If it is raspberry pi why not just modify<br/> /opt/codesys/scripts<br/> so it sets up with<br/> ip link set DEVICE type can fd on<br/> maybe CODESYS will work with that? I don't know but give it a try</p></div>

<div class="markdown_content"><p>We have Raspberry PI with the MCP2518FD chip to connect with CAN-FD devices.<br/> We already know that CodeSys doesn't support CAN-FD natively.</p> <p>Linux System support this chip in kernel, CAN linux interface is visible.<br/> We can operate with CAN-FD devices using cansend and canread commands.<br/> We can also create own application using socketcan linux library, and averything works fine.</p> <p>We need to pass CAN-FD frames TO and FROM CodeSys with about 1kHz frequency and low latency.<br/> What is the best option to make this project as good as possible?</p> <p>a) Try to read CAN-FD frames in external CPP application using socketcan and pass it to CodeSys using udp/serial/shared memory? <br/> b) Somehow read frames directly in the CodeSys by creating own module?<br/> c) use C extension module to get communication with CanFD using socketcan?<br/> d) write MCP2518FD driver directly in CodeSys using SPI?<br/> e) other?</p></div>
