<div class="markdown_content"><p>So I've managed to get CAN running through Codesys but I seem to be having some speed issues. I have the code setup to transmit a message every 1ms. The processor is running at about 90us. I put a CAN sniffer on the network and I can only get about 17 packets per second max out of the pi. Any idea where I might be getting the delay from?</p> <p><img alt="IMG: Capture.JPG" rel="nofollow" src="https://forum.codesys.com//download/file.php?id=1806"/></p></div>
